Iko

Iko is one of the most fearful and dangerous antagonists in the series. He makes his debut in SpongeGod and Triton as the main enemy. He is also the leader of all volcano sea serpents.

Looks
He looks similar to Jeron, but he is way taller and bigger than him. He can constrict anybody to death, has hands that can crush anybody in seconds, and if you want to know how sharp his claws are, they're strong enough to cut even the hardest rocks in half!

Trivia

 * One of Iko's most horrible crimes was trying to kidnap Triton when he was only an infant.
 * Iko is actually immortal (although he isn't immune to getting hurt).
 * Iko's angry roars are enough to break windows and scare even the bravest mortal ever known!
