I NEED to know the name ... it's KILLING me!

There was a cartoon in the 90's I think ... about the same time The Tick was airing. It had a family of brothers. 3 of them were superhero-types and 1 had no powers and was a normal guy. The only episode I remember involves the villain being a pair of mind-controlling underwear that did so by "riding up". They defeated this foe by breaking the band and rendering it powerless.
