Finnivus

Finnivus is an evil tiger shark determined to rule the entire big blue. He is the leader of Indi shiver and likes to eat the head of the leader of the shiver he just defeated. He will also eat the head of any shark in his shiver that he doesn't trust or like. He is so ruthless that he is willing to let hundreds of pups die in battle just to be used as a decoy. Finnivus is killed in battle when Gray bites his tail off and watches him slowly sink into the maw ( a.k.a. the mariana trench).
