Ice King

Ice King’s Role in Adventure Time: Side Quests
Built around the lighter, early-series spirit of the original run, Side Quests drops Ice King back into his natural habitat: causing problems nobody asked for. He occupies that peculiar corner of Ooo where villainy and loneliness overlap, a walking contradiction who kidnaps princesses out of some misguided search for companionship rather than any real appetite for power. The series leans into standalone chaos, and few characters generate chaos quite as effortlessly. His Ice Kingdom, perpetually in disarray, serves as both a punchline and a reminder that somewhere under the crown, Simon Petrikov is still waiting to be found.
Who Voices Ice King in Adventure Time: Side Quests?
Tom Kenny reprises the role he has inhabited since the original series premiered in 2010, returning once more to that uniquely unhinged register he carved out for the character. Kenny is best known as the voice of SpongeBob SquarePants, a role he has held since 1999 and one that earned him two Daytime Emmy Awards, but it is his layered work as Ice King that won him an Annie Award and demonstrated just how far a comedy voice can stretch into something genuinely moving. His ability to pivot from bumbling menace to quiet tragedy in a single scene is what has kept Ice King among the most memorable figures in Cartoon Network history.
