Calling it now, Gobbles is going to become the strongest member of the team.
His gameplay is based around learning, right? But there's nothing saying that how to read is the only learning he can do. He even admits to learning courage from Kit.
So what happens when he gets his hand on some Farcade technical manuals? Or strategy guides? Perhaps gets a mentor in combat or politics?
"Learning" has the potential to be a completely broken ability if he thinks about it the right way. Gobbles could go from Magikarp to Mewtwo.
