All SuperHeroes need an identity or logo emblazoned across their chests, cause admit it, you're not really super if you don't. Above are some easily identifiable logos (if you are unsure of any of them then there is definately no hope for you).
So with the creation of Michty Mo, a logo/badge/crest was one of the important aspects of the design. With some of the previous images you can maybe see the logo taking shape with the character. With the next image below you can see some more development of the logo.
