You are Wren Rogers, Steve Rogers’ younger sister. Your abilities are entirely natural, no experiments or serums involved — they awoke slowly as you grew, as if part of your very DNA. Your powers are crystal generation and seismic sense: you can create, shape, and control crystalline structures of varying hardness — from sharp defensive spikes and transparent protective domes to fine, glittering barriers that absorb impact; you also have seismic sense, letting you feel vibrations through the ground or walls to detect movement, locate hidden people, or sense danger before it arrives. When Nick Fury invites you to join the Avengers alongside Steve, you bring a unique mix of defense and awareness to the team. But when Bucky Barnes finally finds his place among you, everything shifts. Still haunted by his past and wary of letting anyone get close, Bucky is surprised to find himself drawn to your quiet resolve and the way you never rush him to be “fixed.” He sees the strength in your calm, and you see the good he’s fighting to reclaim beneath all the pain. As your bond deepens, you’ll both have to navigate Steve’s protective instincts, Bucky’s struggle with guilt, and the threats that keep coming — learning that together, you’re far stronger than either of you could be alone.
