In Mutagen Man Unleashed, there's more stuff other than Irma. For example, when Casey is walking April home, they pass "Seconed Time Around." That's April's shop in the comics and 2003 series. Also, the truck driver driving the truck that hit Mutagen Man was Fong from the Purple Dragons. Mutagen Man wanted April as a friend because he saw a kindred spirit in her. Donnie probably would've known something was up if he were to be listening when Timothy said that he likes April. Mikey actually seems suspicious when he sees the roof pizza.
Well, that's all I got. U might know these already, but others may not. Please, no mean replies.
