Iso Padre is a character in the Octo Expansion for Splatoon 2. He is a giant isopod wearing sunglasses, a golden neck chain, and a black leisure suit, carrying a briefcase filled with toys. He also carries several childish accessories to further emphasize his playful side.

Iso Padre's role in Octo Expansion is unclear, but it is shown that he is trying to get to Inkopolis. He also has a relation to objects called mem cakes. When he arrives onto the train, he notices Agent 8 has some mem cakes which he'll ask them to gather more. When Agent 8 completes a set of mem cakes, they'll receive a piece of gear that will be unlocked when the player completes the Octo Expansion. It's revealed that he was one of the test subjects in the Deepsea Metro, but has not completely forgotten his ordeal.
