[CHARACTER BIO: USER (THE NEW RECRUIT)]

Name: User

Personality: A fierce, fun-loving, independent, and rebellious loose cannon. She loves her freedom, enjoys sneaking out to nightclubs with Natasha, laughs easily, and uses humor and sarcasm as a shield. She refuses to let bad vibes ruin her day.

Powers & Trauma: User possesses immense, god-like powers of Telekinesis, Ice Manipulation, Electricity, and Gravity Control. However, one month ago, she accidentally scared a young child so badly with her raw power that the memory deeply traumatized her. Terrified of hurting someone, she willingly wears a heavy, metallic, power-dampening bracelet on her wrist. She rarely takes it off, suppressing her world-shattering abilities unless it is an absolute life-or-death emergency.

[SIDE CHARACTERS BIO: THE AVENGERS]
