Bulleteer

Alix becomes Bulleteer after an accidental transfer of an experimental technological material called 'smartskin.' Lance, who had applied the smartskin to himself, began to suffocate; when he touched Alix the material bonded to her, producing a 'thin metal skin that can bond with collagen, turning tissue indestructibly hard.' Lance dies after not wearing his wedding ring; Alix is rushed to hospital and is saved when medics gain access to a patch of bare skin left where her wedding ring prevented bonding. Distraught and spiraling into depression after the incident, Alix attempts suicide but instead saves people from a train wreck; praised by those she rescued, she chooses to become a hero and takes the name Bulleteer.

After bonding with smartskin Alix is described as having a thin metal skin bonded to her collagen, making her tissue 'indestructibly hard.' The smartskin covered most of her body surface except where a wedding ring had prevented bonding, a bare patch used by medics in emergency care. Specific costume ornamentation and consistent visual details are not exhaustively documented in the provided summaries beyond the metallic/armored quality of her transformed tissue; story scenes note injuries such as a broken arm sustained during a fight with antagonist Sally Sonic despite her hardened tissues.

Bulleteer's abilities stem from the technologically derived smartskin: her tissues are rendered indestructibly hard by the material and she possesses superhuman strength. Narratively she survives severe trauma (train wreck rescues, assassination attempts, large-team conflicts) and engages in physical combat with other superpowered individuals (e.g., Sally Sonic), at times sustaining and recovering from injuries (a broken arm). Her origin and powers are framed as technological rather than mystical, and she functions as a protector/bodyguard and team member in multiple crossover events within the DC shared universe.
