Jellyfish, also known as Cecil Balkey, is a supervillain created by Justin Wolfe and a minor antagonist in Bio-Man 2. In Vengeance: Dawn of Oblivion, Jellyfish is a Technical character.


Once a Cortech Industries scientist experimenting with animal DNA in an attempt to create permanent venom antidotes, Dr. Cecil Balkey accidentally injected himself with DNA extract from a jellyfish. Transformed into a glowing poison-themed villain, he built himself a pair of venom-barbed whips, a gun that fires venom-filled syringes, and poisonous smoke bombs.


Jellyfish is a mostly close-quartered fighter as his attacks involve his venom-barbed whips to deal damage. His strong attack, ranged attack, and first ability deal poison damage that slowly drains the health of his opponents.
