–Master Mogul to the army of alternate versions of Tails., StH #151
Master Mogul was a super transformation of Mammoth Mogul. Unlike other super transformations, this form was not brought on by collecting Chaos Emeralds or Power Rings. Rather, Master Mogul has come about through Mammoth Mogul stealing the powers of other Chaos beings. In his first appearance, it was the powers of Enerjak stolen through the use of the Sword of Acorns. Despite his incredible power, Master Mogul was subsequently defeated by the combined might of Super Sonic, Hyper Knuckles and Turbo Tails, with side-line assistance from Athair and the Brotherhood of Guardians. Mogul was trapped inside the new Master Emerald after his defeat. (StH: #56, KtE: #9)
Master Mogul reemerged roughly a year later, after stealing the powers of Chaos Knuckles. When Knuckles returned from the afterlife, it allowed Mogul to tap into this power completely, thus restoring his Master Mogul form. Master Mogul then became bent on destroying the multiverses, going from reality to reality and destroying them, including Mobius-Seventeen. However, after Zonic brought together all the various versions of Miles "Tails" Prower, the Prime version of Tails, using his power as the "Chosen One", fused with all his alternate selves to form Titan Tails, and defeated Master Mogul once and for all. The Chosen One then undid everything Master Mogul had done and returned the multiverses to normal. (StH: #149, #150)
Unlike most Super Transformations, Master Mogul did not undergo a change in coloring in his first appearance. Instead, his attire transformed into a gold set of armor with a flowing red cape and matching kilt. He also wielded a large wooden staff with a green stone atop it. In his second appearance Mogul's fur was tinged green, and his attire was also green-colored. The second version was also many times larger than the first, which remained roughly Mogul's natural size, and had glowing green eyes.
