Ever noticed something about the FW characters that have been brought back recently?

Most of them were not frequent. Aside from Bebop, Rocksteady, Krang, Irma, Vernon and Thompson (and really, Irma's comeback was an elaborate joke and Thompson was more for Whoopi Goldberg to be squeezed into a cameo).

Chrome Dome, Mutagen Man, Joe Eyeball and Muckman were only in one episode each. Mondo Gecko and Metalhead only got two (and their second appearences are rather minor). Slash got three and the Neutrinos got five. Technically speaking, characters people want to forget about like Zach were more frequent.

Wonder why? Maybe there's more nostalgia for the toys of the characters rather than the characters themselves?
