That´s true Dormammu need some aliases to be a good battle. Dormammu & Shuma Gorath & Mephisto & Satannish vs Mr. Mxy "
If this is magical Mxy then putting Shuma against him is an overkill and giga curbstomp for Shuma. Cause that mxy is just a big snack for our magic-eater Shuma. "
mr mxy isn't really magic but rather science from the 5th dimension but to us it may as well be magic and even if shuma got some back up with the individuals mentioned above it makes no difference to the outcome
