[3] Raised in the small Mexican village called 'El Chilar', Miguel Barragan grew up in a loving and supportive community, and found acceptance as an openly gay teenager.

When Miguel manifested the metahuman ability to create psionic energy constructs, he sought out Red Robin in an attempt to become a full-fledged superhero.

Miguel – who adopts the code-name "Bunker" – then becomes a target of N.O.W.H.E.R.E., a mysterious organization abducting super-powered youths for their purposes.

Red Robin makes contact with Bunker, and soon organizes a group of targeted teenagers into a resistance force known as the 'Teen Titans'.

He has full control over their density, being able to make them soft to cushion impacts or falls, or hard as rock to inflict damage.
