Trivia

 * Similar to Wakando his backstory was not made yet until after his debut episode
 * Seeing as how Doc Ock warns Grevious of how dangerous it is and how they act to get it back it seems they realize it’s an expierment gone wrong and make sure it doesn’t do any harm.
 * Its name was revealed in “Mega Man Fully Charged”
 * It can control anybody wether they are robotic or not as how it can control Chompy an organic being and Robosaur a robotic being. As it attaches itself to them.
 * It is unknown what has become of it after “Mega Man Fully Charged”
 * His name was originally meant to be Overmind as a reference to the also sentient A.I. Chip from TMNT 2012 Series but this name was already given to the mutant character Overmind, Master Mind was chosen Instead and was a much better name due to the meaning of his name.
