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 existance under the seas would have remained unknown to the Freedom Fighters had Tails not encountered him during the maiden voyage of the Sea Fox. Octobot hates Tails with a passion almost as strong as Crocbot and would also gladly kill him for virtually ruining his many plans. Discovering the underwater roboticisation factory once mainted by Jaws ( One of the badniks from Sonic 1), 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 drug Tails beneath the ocean in an attempt to drown him. Tails was rescued by The Forty Fathom Freedom Fighters - a group of underwater FF's and later saved, but Octobot's fate during the rescue? Crushed beneath the massive weight of thier largest member - Fluke The Blue Whale. Octobot survived the incident - though somewhat flat - and hasn't been seen since: most likely stewing in his own juices over revenge. But it is known that he is not completely destroyed and still continues to hold a HUGE grudge against the guy that started it all - Tails The Fox.

You think that Sonic's world is populated by all animals with Snively and Robotnik being the exceptions? Think again...Overlanders are in quite large abundance on the planet, but are only concentrated in small areas. Not making much interaction with the "mutated animals" of the planet, Overlanders are perceived as warlike, quite willing to kill whenever necessary, and often VERY dangerous. In fact this is the species that Doctor Robotnik and his nephew Snively hail from. Usually in Flashback sequences, The Kintobor family (Robotnik) seems to hold high position in Overlander society. In fact just like society today, their society operates like ours - only more contained and futuristic. there are judges, police, scientists, large armies, black people, white people, etc...the list goes on and on. For now the first person in Sonic's world that has disproven the "sterotype" that all Overlander's are bad is Nate Morgan. The Great War against the Overlanders and The Kingdom Of Acorn before Robotnik's near planetary takeover, the Overlanders being responsible for the coma of Queen Alicia and death of Geoffrey St. John's father - even Robotnik's presence alone is enough to give them all a bad name. Anti-Overlander sentiment (racism) often runs rampant among the furries, but not all the Overlanders are villians, but not all of them are exactly friendly. Their origins on the Planet Mobius, however, still remain a mystery...
