Fighter Teams are one of the easiest teams to form because Chef Zeff is farmable...even though it may take a while. Also, Fighter units are found everywhere; however, Fighter teams aren't the most powerful and are mostly outclassed by other teams.
Captains
Namule (Namur): 7.5/10 Namule can give Fighters an edge in HP, but it's not enough HP to make him the greatest captain. Namule is a great fighter with good stats and a good special, but as a captain, he is still outclassed by the Chef.
Chef Zeff: 8/10 Compared to Jinbei, Zeff has crummy stats and his special isn't really suited for Fighter teams. Still a powerful captain.
Jinbei: 10/10 His stats are pretty powerful, he shares the same captain ability as Zeff, and he has a pretty helpful special with a really short cooldown.
