Oh, Raph is still male. But "vamp" can apply to male characters as well as female characters. It's sort of like calling another gay guy a "bitch." I actually frequently call Raph a bitch (and we love him for it). Perhaps "vamp" wasn't the best use of the word in this case, but I improvised. If I gave it more thought, I'd call him...okay, a vamp&mdash;a destructively manipulative person whose actions can't easily be excused. XD

IDW mutagen is actually a very rare substance. It was originally the lifeblood of the Utrom homeworld Utrominon, but that planet has since been destroyed under the reckless leadership of General Krang's father. Krang took the surviving members of his species to Burnow Island on Earth, intending to use it as a base to plan for the complete terraformation of the planet into a new Utrominon where Utroms could live (but other life would die). (Where did you think Nickelodeon got this idea for the Kraang's Earth plans? XD The IDW plot was written first under Nick's license before Nick started making their own TV show.) Krang brought a supply of mutagen, and the other Utroms are in stasis in mutagen vats. I can't remember how Stockgen got its supply of mutagen that was used to mutate Splinter, the turtles, Old Hob and Slash. Karai also infiltrated Burnow and drained one of the Utrom stasis tanks of its mutagen, killing one Utrom in the process, and sneaking the supply back with her to the Foot Clan, which is how they've been able to make their newer mutants, and also outsourced some of their mutagen to the Null Corporation to make experimental mutants, which were later freed and joined the Mutanimals. At least three other characters in poor physical shape have been revitalized back to health with mutagen without mutating into new different animals.

Such a timeline explanation is...too much of a cop-out to excuse what is essentially bad writing. XD See Voodoo Shark.
