|First Appearance||Splatoon (2015)|
Octodivers look about the same as a regular Octotrooper: looking like a red-and-white tentacle with their hairstyle-like tip acting as a hand. The largest difference is that they also wear a pair of diver goggles and a snorkel in black and bright cyan. The device they ride is also largely the same except for one thing: certain parts are rimmed sky blue.
