#2 Tama Tonga
Tama Tonga is another guy who has been a foundation on which the Bullet Club has enjoyed continual success. The adopted son of Haku has proven to be both a special talent in tag matches and in single matches.
He's held the NJPW Heavyweight Tag Team titles four times and is the current champion with his adoptive brother, Tanga Loa.
Tonga is another guy who just oozes charisma. He's always singing and rapping when he's headed to the ring and he understands that facial expressions are just as important as your physical ability on the mat.
Tama seems like a smaller, quicker and (hard to believe) even more explosive version of Roman Reigns. His fluidity between the ropes is impressive.
If WWE were to sign him, they'd have to let him be himself. Let him be loud and brash. He can certainly back it up in the ring and doesn't seem like someone who would back down from anyone. Just don't put him in the dang Cruiserweight Division.
