Ramses is a summon from the Golden Sun series. He is based after eleven Egyptian pharaohs of the 'New Kingdom' period.
In the original Golden Sun, Ramses is summoned using two Djinn and as a base Venus power of 60 and also does additional damage equivalent to 6% of the enemy’s maximum HP. It is the exact equivalent of using two Venus Djinn at once. In Golden Sun: The Lost Age, Ramses is the exact same as the first game, but has a different background when summoned.
He returned in Golden Sun: Dark Dawn.
