Nice work [@Biscuits], I like where you're going with the character. I somehow imagine (a younger) Paul Sorvino filling that role.

So is Brook able to shapeshift into any animal, or animals that are closer to his size/weight?

Is this an at-will power, something that happens as a defense mechanism, or randomly? I know for my character (Vincent), his has been almost exclusively defensive, but as the story progresses, he may or may not learn how to freely trigger it. But that remains to be seen.

So are both you and [@Stitches] character travelling together?

In any case, [@AcerRo] will let you know his thoughts since he is the final say.
