Diego is a lean but decently muscled man courtesy of marine training. Sports a goatee but has been known to mix up his face hair styling every now and then, the previous one being a thick moustache.

His m3 armor has a rendering of a day of the dead skeleton shooting two pulse rifles in the air.

Hailing from what was formerly known as mexico in the center of the now United Americas, his origins are easily discerned from his thick accent and frequent latin outbursts. He was born into poverty and ran with street gangs as a youth before getting arrested as part of a drive to clamp down on the increasingly violent gang warfare.
Given the choice between prison and service in the marines, Diego chose the latter, much to his regret at times now that he chokes under regulations and rules and having to follow "orders". But after getting himself on latrine cleanup duty more then a few times for insubordination he learned to bite his tongue somewhat.
Still at least the money is nice by his paltry standards, he might be one of the few marines who actually does believe every paycheck is a fortune and he sends back what he can to his family.

Has been known to get a tad overexcited and trigger happy in combat as he goes "loco".

He is superstitious and religious, always having a cross on a silver chain around his neck so "la luz de dios" can protect him no matter what backwater planet the corps sends him to.
