Freedom Fighter group


N/A (after Robotnik's coup)

Resident location 

Mobian Sea


The Forty Fathom Freedom Fighters are a group of aquatic Freedom Fighters aiming to keep the Mobian Seas clean from the tyranny of Dr. Ivo Robotnik and later Dr. Eggman. The group was first discovered by Knothole Freedom Fighter agent Miles "Tails" Prower while he went on his mission to Downunda. The FFFF's have faced off against Octobot on numerous occasions and were later responsible for stopping the misfit Badniks from turning Pseudo-Sonic into an ultimate weapon. They receive assistance from the Plankton Intelligence Agency, a network of plankton that keeps them up to date on anything going on in the oceans.



When Tails was captured by Octobot, the robot nearly drowned him. However, the Forty Fathom Freedom Fighters managed to arrive just in time to save Tails' life and force Octobot to flee. From there, Big Fluke brought Tails to the continent of Downunda as his Sea Fox submarine was damaged by Octobot. Later, when Tails wished to return to Knothole, the Forty Fathom Freedom Fighters presented him with the repaired Sea Fox, enabling Tails to return home. (TMS: #1, #2, #3)

Some time later, the Forty Fathom Freedom Fighters found themselves facing off against aquatic gangster Eel Capone, who had ousted Octobot and taken over a large section of the sea. Bottlenose managed to overpower Eel Capone through his Finja training, succeeding where his teammates had been defeated, and freedom was restored to the seas. (SMM)

Stopping the Badniks[]

Years later, the Forty Fathom Freedom Fighters discovered the sunken Island of Misfit Badniks, where the various surviving Badnik robots were attempting to rebuild Pseudo-Sonic after his latest confrontation with Sonic the Hedgehog. The group managed to destroy most of the Badniks, with Fluke compacting them into a cube. (StH: #185)

Background Information[]

  • The Forty Fathom Freedom Fighters are amongst the few Mobians introduced in the old continuity who possess few anthropomorphic qualities other than the ability to speak. It is unknown whether they will return in the post Worlds Collide reality, as well as how their appearance might be addressed given the introduction of such undersea Mobians as the inhabitants of Meropis.
