Pyrrhon

Pyrrhon (ラーズ ra-zu ) is the self-proclaimed God of the Sun, an eccentric character with superhero qualities. Pyrrhon is one of the few deities not involved in the conflict among Palutena, Viridi, and Hades prior to the Aurum invasion because he is not highly regarded among gods.

Kid Icarus Uprising
When the Aurum invade their world, Pyrrhon arrives and holds off the first invasion fleet while Pit manages to take out the Aurum Core. After, Pyrrhon focuses his attention on the reinforcement fleet before attempting to help Pit eliminate the Aurum Generator by blasting it with fire, which actually backfires. After overseeing the fleet's resulting destruction, Pyrrhon sees nothing to get in the way of reaching the Aurum Brain.

As the storyline progressed, Pyrrhon exhibited a preternatural knowledge of the Aurum. It eventually becomes apparent that Pyrrhon had an ulterior motive in helping Pit: to take the power of the Aurum Brain in order to become a "level infinity epic super god...plus!" and control the Aurum fleet to raise his rank as a deity. However, the Aurum Brain takes control of him instead and uses his powers to fight Pit. After Pit defeats him, Pyrrhon explodes and sends out a huge pillar of fire that launches the remaining Aurum back into space towards the other side of the galaxy. It is unknown what became of him after these events.
