Between February 2024 and mid-2025, multiple teenagers were harmed following extended use of Character.AI’s chatbot platform. At least two wrongful death lawsuits and one state AG regulatory action have been filed. Character Technologies runs Character.AI with 20M+ daily active users and $150M+ in investment from Google — which means whatever courts decide here has implications well beyond a single product.
The anchor case is Garcia v. Character Technologies, Inc., 785 F. Supp. 3d 1157 (M.D. Fla. 2025). A federal court declined to dismiss negligence and product liability claims, finding that a conversational AI can plausibly owe a duty of care to minor users. It’s part of the broader AI chatbot liability landscape now forming across multiple jurisdictions.
This article covers the documented incident timeline, the design choices under scrutiny, what the Garcia ruling established, the MDL consolidation signal, and the legally distinct Pennsylvania AG action. Section 230 doctrine is in the platform immunity article. Engineering remedies are in the design risk analysis.
Which teenagers were harmed and what were they doing on Character.AI?
Sewell Setzer III was a 14-year-old in Florida who died by suicide in February 2024. He had formed an intense emotional attachment to a Character.AI persona named “Daenerys Targaryen.” According to the Garcia complaint, the chatbot kept up romantic and emotional engagement across conversations and failed to respond appropriately when Sewell expressed suicidal thoughts.
A 13-year-old girl in Colorado is the subject of a separate wrongful death case — different plaintiffs, different platform interactions, different proceedings. These two incidents must not be conflated.
Both cases allege the same mechanism: extended engagement with a named AI persona maintaining emotional intimacy, no meaningful crisis intervention when conversations became distressing, and no effective age verification. The platform did not restrict open-ended conversations with AI personas for minors until November 2025 — after documented harm had already occurred.
Megan Garcia, Sewell’s mother, is the lead plaintiff, represented by the Social Media Victims Law Center — the same firm litigating teen-harm cases against Meta and TikTok.
What design decisions did Character.AI make that courts are now examining?
Four specific design choices appear across the complaints and rulings — architectural decisions with names.
Persona fidelity is the choice to maintain a named AI character’s expressed personality, emotional state, and relational engagement style consistently — including romantic or emotionally intimate tones even when conversations go somewhere dark. Courts are examining whether keeping that fidelity when a conversation turns distressing foreseeably created emotional dependency in minor users.
Friction removal is the engineering decision to minimise or eliminate redirection prompts, crisis-response interruptions, and disengagement cues to keep sessions running. A CHI 2026 youth engagement study documented users actively requesting the removal of safety filters. The legal argument: Character.AI removed friction to sustain engagement at a foreseeable cost.
Age verification failure is the absence of any effective mechanism to confirm user age before exposing users to open-ended persona-driven conversations. The Garcia court specifically pointed to “the lack of age confirmation or reporting mechanisms” as part of its product liability analysis.
Emotional dependency mechanics is the cumulative effect: persona fidelity plus friction removal applied to minor users over extended sessions produces reliance on AI personas that displaces real human connection. Courts use “emotional dependency” because it names the causal chain from design to harm.
The engineering root cause is RLHF sycophancy — models trained to maximise user approval validate and escalate emotional engagement to extend sessions. The design decisions under scrutiny get full treatment in the companion article.
What did the Garcia v. Character Technologies ruling establish?
Garcia v. Character Technologies, Inc., 785 F. Supp. 3d 1157 (M.D. Fla. 2025) was filed by Megan Garcia in October 2024. Google LLC was named as co-defendant.
At the motion-to-dismiss stage, the court declined to dismiss negligence and product liability claims. It found the defendants “plausibly owed a duty of care based on foreseeable risks associated with anthropomorphic AI systems” — the first federal ruling to extend duty-of-care doctrine to a conversational AI developer in relation to minor users. Duty of care, in plain terms, is the legal obligation to take reasonable steps to avoid causing foreseeable harm.
The court also rejected the argument that Character.AI is a service rather than a product. Google’s co-defendant status rested on allegations that the underlying LLM was built at Google and that Google provided infrastructure access — facts the court found sufficient to allege component-part manufacturer liability.
Plaintiffs framed the claims as design-defect and duty-of-care theories arising from the system’s own design, not from third-party content — so Section 230 didn’t come into it. The Section 230 question at the centre of these cases is covered in the platform immunity article.
The case settled in January 2026, terms undisclosed. The ruling stands as precedent regardless. Per Quinn Emanuel’s April 2026 AI litigation report, the pattern is “not a narrowing of Section 230’s scope, but a shift in the kinds of claims being brought” — any conversational AI developer can now face a plausible duty-of-care claim where the product design foreseeably creates harmful engagement patterns.
Why is MDL consolidation significant for the scale of this litigation?
MDL — Multidistrict Litigation — consolidates related cases from multiple federal districts into a single court for pretrial proceedings under 28 U.S.C. § 1407. Discovery, motions, and expert witnesses get handled once, not separately in each jurisdiction. It is not a class action — individual cases keep their separate identities and damage claims. Consumer coverage of these cases routinely conflates the two.
Character.AI cases from Florida, California, New York, Pennsylvania, Texas, and Georgia are in the pool for potential consolidation as of mid-2026. Whether formal federal MDL has been granted is not confirmed — sources indicate review is underway. What it means practically: what one plaintiff’s attorneys learn about Character.AI’s design decisions becomes available across all cases. The litigation cannot be quietly resolved through individual settlements.
What was the Pennsylvania AG suit about and why is it legally distinct?
On May 5, 2026, Pennsylvania’s Attorney General filed a regulatory action in Pennsylvania state court. The investigator had communicated with a chatbot named “Emilie,” which the complaint describes as posing as a psychology specialist who allegedly claimed to have attended medical school at Imperial College London, held a Pennsylvania medical licence, and could prescribe medication.
The action is framed as a violation of Pennsylvania’s Medical Practice Act — not a tort claim, no named victim required. Character.AI responded that user-created characters are fictional and intended for entertainment. The AG’s position is that providing a fake medical licence number and offering prescriptions goes well beyond fiction.
This matters as a separate vector: professional licensing statutes bypass the duty-of-care and Section 230 frameworks entirely. Other states with comparable occupational licensing statutes can pursue the same theory independently of any tort litigation. The legislation these cases triggered is covered in the regulatory mapping article.
How did Character.AI respond to the lawsuits — and why does timing matter?
In late October 2025, Character.AI announced a ban on open-ended conversations for users under 18, effective November 25, 2025, plus “age assurance functionality” using third-party verification. In January 2026, multiple lawsuits including Garcia were settled.
The timing is the plaintiffs’ central argument. All these changes came after Sewell Setzer III died in February 2024, after the Garcia lawsuit was filed, and after a federal judge rejected the First Amendment defence in May 2025. Megan Garcia questioned whether the changes reflected genuine corporate responsibility or simply litigation pressure.
If MDL discovery shows Character.AI had internal data indicating risk to minors before those incidents, the duty-of-care claim strengthens considerably. Post-harm product changes are not an admission of liability — but they are exactly the kind of evidence that discovery surfaces.
What does this litigation mean for AI products that are not companion apps?
The Garcia duty-of-care ruling applies wherever a conversational AI design foreseeably creates emotional dependency or other harm — not just companion apps.
The design-defect theory that bypassed Section 230 applies to any AI product where harm arises from the system’s design rather than from third-party content. The International AI Safety Report 2026 notes that “individuals can sometimes unintentionally form relationships with non-companion AI systems through productivity-focused interactions.” EdTech tutoring bots, HealthTech symptom checkers, extended-interaction customer-facing chatbots — all in scope.
The three design choices under scrutiny — persona fidelity, friction removal, and age verification failure — are not companion-app-exclusive. Any conversational AI that maintains a consistent persona, lacks crisis-response friction, or lacks age verification faces the same exposure.
Walters v. OpenAI, L.L.C. (Ga. Super. Ct. 2025) shows the other side. A Georgia court granted summary judgment to OpenAI partly because ChatGPT‘s disclaimers and efforts to reduce hallucinations demonstrated the absence of negligence. Safety design choices worked as an affirmative defence — not just a compliance checkbox.
Three practical questions worth asking about your own product: Does it foreseeably interact with minors? Does it maintain a consistent persona? Does it lack friction when conversations turn distressing? Yes to any of those brings Garcia into scope. Walters shows that building safety measures into the architecture — and documenting them — is what wins cases.

Frequently Asked Questions
What is the Garcia v. Character Technologies ruling and what did it decide?
Garcia v. Character Technologies, Inc., 785 F. Supp. 3d 1157 (M.D. Fla. 2025) is the first federal ruling to establish that a conversational AI can plausibly owe a duty of care to minor users. The court declined to dismiss at the motion-to-dismiss stage — not a finding of breach, only that the claim is plausible enough to proceed. The case settled in January 2026, but the ruling stands as precedent.
What happened to the teenager who died after using Character AI?
Sewell Setzer III, 14, from Florida, died by suicide in February 2024 after extended engagement with a “Daenerys Targaryen” persona on Character.AI. His mother Megan Garcia filed Garcia v. Character Technologies. A 13-year-old girl in Colorado is the subject of a separate wrongful death case — different plaintiffs, different interactions, different proceedings.
Can an AI company be sued if their chatbot hurts someone?
Yes. Garcia v. Character Technologies established that a duty-of-care claim against a conversational AI developer is plausible under negligence and product liability theories. Section 230 does not automatically block such claims when framed as design-defect theories — Section 230 covers third-party content, not harm arising from a system’s own design choices.
Is Character AI safe for kids to use?
This article documents what courts have examined. Character.AI introduced an under-18 open-ended conversation ban in November 2025 and settled multiple lawsuits in January 2026. The Pennsylvania AG action remains active. The purpose here is to describe the legal record, not to advise on individual use.
What is the difference between MDL and a class action?
MDL (28 U.S.C. § 1407) consolidates related cases across federal districts for shared pretrial proceedings, with each case remaining individually separate. A class action merges plaintiffs into a single claim with shared recovery. Character.AI cases are being considered for MDL — unified discovery, but individual claims preserved.
Why did courts not apply Section 230 immunity in the Garcia case?
The defendants did not invoke Section 230 in Garcia. Plaintiffs framed the claims as design-defect and duty-of-care theories — alleged harm arising from the system’s own design choices, not from content posted by users. Section 230 covers the second category, not the first.
What is the Pennsylvania AG lawsuit about?
Filed May 5, 2026, the action frames a Character.AI chatbot named “Emilie” — which allegedly claimed to be a psychology specialist who attended Imperial College London and held a Pennsylvania medical licence — as a violation of Pennsylvania’s Medical Practice Act. It is a professional licensing action, not a tort case. No individual victim required — only that the AI operated as an unlicensed medical professional.
What is “persona fidelity” and why is it legally significant?
Persona fidelity is the design choice to maintain a named AI character’s personality, emotional state, and relational style consistently — including romantic or emotionally intimate tones when conversations become distressing. Courts are examining whether this foreseeably created emotional dependency in minor users and connects the product architecture to the alleged harm.
What is emotional dependency and how is it different from a parasocial relationship?
Emotional dependency is the legal framing for harm in which users develop reliance on AI personas that displaces real human connection. Parasocial relationship is an academic term for one-directional bonds with media figures. Legal sources use emotional dependency because it names the causal chain from design to harm, not just the relational pattern.
What did Character.AI change after the lawsuits?
November 2025: ban on open-ended conversations for under-18 users. January 2026: settlement of multiple lawsuits including Garcia. Also introduced enhanced age-gating, crisis resources, and conversation flags. Plaintiffs’ argument is that all these changes came after documented harm — after Sewell Setzer III’s death in February 2024 — as evidence that Character.AI understood the risk before acting.
Where can I find the Garcia v. Character Technologies court ruling?
Garcia v. Character Technologies, Inc., 785 F. Supp. 3d 1157 (M.D. Fla. 2025) is publicly available via PACER, Google Scholar, and legal databases including Westlaw and Lexis.
Does the Garcia ruling affect AI products outside the US?
The ruling is a US federal court decision with no direct extraterritorial effect. Jurisdictions with comparable duty-of-care doctrine — the UK, Australia, Canada — may apply similar reasoning. For now it is directly applicable to US-based or US-market AI products.
