Sparker (voiced by Scott Pincus) is an intergalactic warrior from a faraway universe. He’s led a tragic life, constantly losing his friends in battles throughout the cosmos. He claims to have saved the multiverse “five or six times” and and stubbornly believes that due to his successes in battle it is his responsibility to ensure the safety of every world. Sparker travels from universe to universe liberating planets from the tyrants that rule them, but once he comes into contact with Darkseed he is faced with an evil power that even he cannot defeat alone.

Sparker carries a staff that gives him the power over electricity. He often wears armor and a mask that covers his face. Upon seeing his true face, Alice develops a crush on Sparker.
