Shelter was separated from his family during the invasion, then processed into a resettlement camp. When he started showing signs of psionic aptitude, he was shipped off to an ADVENT research facility for human-born psions. ADVENT forced him to use his abilities to harm others, and he ultimately fled their control.

Now part of XCOM’s Chimera Squad, Shelter prefers to use his psionic powers defensively. He buffs his allies, relocates both friend and foe, and can even create a psionic clone with those same abilities.
