Squishball
Squishball the slime enters Rivals of Aether. He has a simple but effective gameplan using his great aerial movement, tied in with his gimmick. He can shoot a slime ball from his arm that, when it connects, will charge Squishball with slime energy to change his Slime Spikes attack into Slime Energy Finisher: a difficult to connect move that can KO very easily.
