Dave isn't the sort to let someone kick him and take his buds away. He'll be exploring and gathering info on everything he can and assisting whoever he runs across. His main objectives are as follows: A. Get his pokemon back.
B. Gather deets on whatever the place is.
C - a. Find anyone that needs help and do what he does best.
C - b. Get the hell out.

He'll use anything he can get his hands on and isn't afraid to go toe to toe with anything coming at people. He's very likely to protect weaker characters as well as go on solo mode if he needs to. This is that time that Dave is very little jokes and all about doing what needs done.
