Who to use as 5th character for bad batch and which zetas?

I just been playing around with them in GW. GK and Cody are the two I’ve been using mostly just for the mass attacks.

I think ultimately if you are gonna use them for a GA/ TW/ TB team at some point you would want all the zetas. I think once we get Crosshair they are gonna be a good team, he will be their main source of damage.
