Yes, Omen was quite different in his youth, he was made to be a living weapon and that is what he is....

But How does he go from the guy that Never smiled to the Joe trolls we know now?

( he looks funny with very short hair, he didn't start growing it out until later)

His guns we're part of his armor so he doesn't have them anymore, and it's a good thing because like his armor they were OP and the Spears above him we're nasty business to, you wouldn't like him back in the old days

The Vaseterm at one time was very advance in Magic and Technology but that changes after the fall
