Octodad is an orange octopus who disguises himself as a human. He works as a stay-at-home father married to a human woman named Scarlet, who he met after stowing away on the fishing boat of a deranged chef named Chef Fujimoto, and they have two children named Tommy and Stacy. Despite his animalistic appearance, clumsy movements, and lack of human speech, he is able to live normally among humans without his true identity being suspected, even by his own family. The only person who does seem to know his identity is Chef Fujimoto, who has a bitter grudge on Octodad and frequently stalks him in an attempt to expose or even murder him.
Being an octopus, Octodad has a strong grip that allows him to latch onto things easily. He also has long reach with each of his tentacles, but his lack of bones makes them difficult to move naturally. His movements can be erratic and reckless, frequently causing him to knock things over.
Octodad appears as a playable character in Fraymakers and is among the six characters initially revealed for the game. His design is based on his appearance in Octodad: Dadliest Catch. His moveset utilizes his long-reaching, flexible tentacles in the Octodad games, giving him a long reach and unique attacking angles at the cost of leaving him vulnerable.
