I actually remember this as a kid (as it debut the same year as Darkwing Duck, another superhero cartoon I like). Hammerman is another in a long line of cartoons based around real life famous folk. The celebrity this one focuses on is MC Hammer, who everyone knows for hits like "Can't Touch This".
Basically, this cartoon tries to turn MC Hammer into a superhero. The origin story we get is in the theme song, as youth center owner Stanley Burnell is visited by Grampa, an elderly man who back in the 60's and 70's, fought crime as Soulman, wearing a pair of magic talking shoes to transform. Stanley is given the shoes, and when he puts them on, he becomes Hammerman, and with the power he inherits, protects the city of Oaktown from wacky supervillains themed after various crimes.
Yeah, we can already tell this is going to be a train wreck, as the series only lasted thirteen episodes before being yanked off the air. Basically, the series is another one of those preachy shows meant to educate kids on stuff (the pilot episode "Defeated Graffiti" teaches about how bad graffiti is, Rapoleon is supposed to teach about not picking on those smaller than yourself, etc). Sadly, they fall through. Each episode has a live action wraparound introducing the lesson the episode teaches, and at the end, it has MC Hammer himself lecture to the kids about what they learned. But when it gets to the animated segment (you know, what the kids want to watch), that is where it falls apart. The villains used are basically based on actual crimes (Defacely Marmeister, who debuts in Defeated Grafitti, is based on vandalism via graffiti, and has the power to turn graffiti into monsters, and Rapoleon is a Napoleon clone who wants to shrink Oaktown because, get this, people picked on him for his small size). Seriously, these villains sound like bad guys who would be either B-listers or C-listers. Also, the episodes do a horrible job teaching the moral, and the animation is a bit iffy (Defeated Graffiti is the worst, as it has static animation, making it look more like a pilot pitch than an episode for air). This is one stinker to avoid.
