Trivia

 * The name is a reference to the planet Mobius, where the old Sonic comics took place. Since Mobius doesn't exist in the IDW comics, the character Mobius the Penguin was created solely to be used as a namesake for the PMC while avoiding reference to the old Sonic canon.
 * [MSF] was the clan tag PT used while playing Call of Duty 4 circa 2009-2010. He claims that that version of the Mobius Special Forces was created to combat the H1N1 clan.
