Octobot is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a blue octopus Badnik with eight drill-like tentacles. He is one of Dr. Robotnik's underbosses.
Far beneath the surface of the Great Mobian Ocean rests an underwater bot base—home of the malicious Octobot, a giant blue mech squid that serves as one of Robotnik's underbosses. In fact, Octobot's existence under the seas would have remained unknown to the Freedom Fighters had Tails not encountered him during the maiden voyage of the Sea Fox. Discovering the underwater roboticization factory once maintained by Jaws (one of the Badniks from Sonic the Hedgehog (1991)), Tails destroyed the submerged base and left Octobot a complete laughing stock among the bot community.
However, what Tails didn't know was that Octobot wanted revenge—and while on a mission to prove himself in Downunda, Octobot scuttled the Sea Fox by puncturing it with his drill tentacles and dragged Tails beneath the ocean in an attempt to drown him. Tails was rescued by the Forty Fathom Freedom Fighters, a group of underwater Freedom Fighters, and later saved, while Octobot was crushed beneath the massive weight of their largest member, Fluke the Blue Whale. Octobot survived the incident, though was somewhat flattened. He later reappeared, fleeing the only undersea villain more fearsome than himself: Eel Capone, the undersea gangster.
Octobot hates Tails with a passion almost as strong as Crocbot and would also gladly kill him for virtually ruining his many plans. Like many of Robotnik's sentient creations, he is highly volatile. Octobot's assignment has naturally affected his behavior, from sailor jargon to mentions of Davy Jones' locker.
