Khalifa: HP: 1728. ATK: 963. RCV: 378 Rank: 5.5/10 Special: All orbs into either STR or DEX. Random damage to all enemies. Her special really is only good for a DEX team and her stats aren't the greatest; however, since DEX Fighters are very limited, she can be alright.
Bellamy: HP: 1072. ATK: 986 RCV: 170 Rank: 7/10 Special: 1.5 Orb Boost for 1 turn. Bellamy is a decent Orb booster. He will be outclassed by the other fighter, Coby, but that doesn't mean Bellamy is bad. There's not too many great DEX fighters, so Bellamy might be your pick.
Chef Zeff: HP: 908. ATK: 698. RCV: 164 Rank: 4/10 Special: STR into DEX orbs. Outside of a captain, Zeff sucks. All he can do is convert orbs. Decent for a DEX team, crummy for a Fighter team.
Namule (Or Namur): HP: 2398. ATK: 1303 RCV: 262 Rank: 9/10 Special: 1.5 Fighter Boost and Damage to 1 enemy. Namur is pretty awesome. He provides a boost which is always loved. His stats are very solid as well.
Guard Point Chopper: HP: 1320. ATK: 408. RCV: 184 Rank: 5/10 Special: 50% damage reduction for 3 turns. His special can help save your life; however, that's all he can really do. His stats suck.
Log Sanji: HP: 2350. ATK: 1052 RCV: 208 Rank: 6.5/10 Special: Reduce enemy HP by 10% and QCK orbs into DEX. Sanji should be way better, but at least he's usable. Cutting HP is always nice and his stats aren't too bad.
