I actually got the impression that Daycan might be more emotional, a little foolish sometimes and perhaps a little more hot-headed, as compared to Deathclaw. A bit of a dynamic. He does seem like a character that could conquer the world by himself with his brains at this iteration. (Deathclaw can't do that. She's a little bit unhinged from the transformation messing with her head, despite being mostly sane.)
