Zeru the Experiment

Was created in a lab and used for many experiments (genetic and otherwise)

2 years ago he was released due to a new law regarding experimentation on sapient beings

Was not properly socialized before being released, so he sometimes does unorthodox things

He is always watching and listening, weary of new people but also interested in them

He is very smart but tends to keep quiet

Sometimes goes for walks just to find someone to fight (something he's more familiar with than one would normally be)

He was never given a proper name so he goes by "Zeru" (short for "Zeru-Zeru-Won")
