I am sure TTM is not very fast, which is why I said he would work best attacking from a distance (he has insane throwing power) and only as a distraction.

Been a while since I read through the manga, but I didn't get the feeling that Pig God is fast enough to stand up to Vaccine Man. He did get rek'd by Gums after all, and I would certainly consider Gums a weaker dragon than Vaccine Man.

TTM can at least attack from a distance and act as support, but Pig God has to get up close, and if he was beaten by Gums, he would be beaten by Vaccine Man.

This is my analysis anyway, maybe someone can change my mind with feats and/or logic I may have overlooked.
