Unlike his future self, Weisz is a selfish and stubborn person who only cared for himself, acted as if he didn't truly care about the others around him.

As Arsenal, Weisz tends to act heroic and bombastic with flashy speeches, insisting to his crewmates that he is being in-character of his superhero persona.
