Mr. D

Mr. D is the image of Death incarnate—most likely the darkest and most terrible villain Frogger has ever faced. He is in every way perilous and cold-blooded, seeking to wreak havoc in Firefly Swamp, by stealing the four sacred elements which keep the swamp alive. When he first attempted this ("Frogger's Adventures: Temple of the Frog"), he was eventually confronted by Frogger, who used the elements' various powers against Mr. D, causing him to evaporate. For several years afterward, he was never heard from again.
