San-Jay Protogen from a previous universe that Polus visited after escaping his own universe, in San-Jays world, Protogens are at war with humans because a certain religion called jo-uhn-tanianity has declared Protogens as against the gods of jo-uhn, even though they did nothing wrong, luckily, the Protogens won the war and created new laws to avoid discrimination.
If you're wondering San-Jay is a straight male,
and his hair glows because of the way his universes particles interact with the particles in the universe he's currently in.
