I decided to create a trio of antagonists consisting of three sea creatures you may not be too familiar with, so here's The Typhoon Trio!

Xaria is a thorny seahorse and the leader of the group. Not only is she scheming and manipulative, but she is also really intelligent. She can project her own spines to attack and they can grow back very quickly.

Itzel is a peacock mantis shrimp who is rough, tomboyish, and reckless. She can create pyrotechnic sparks from her claws and can release those sparks when she punches her opponent which can burn them and causes the water around her to boil. She also has excellent eyesight as well.

Exton is a porpoise (specifically a harbor porpoise) and the muscle of the group. He may not be the brightest one of the bunch, but he is really strong and can lift and carry heavy objects such as an anchor.
