Dynamozx05: There is precedent in the TMNT multiverse, also involving Donatello. Donatello (Image) not only became a cyborg for all of volume 3, but the metal and electronics joined with his biology on a cellular level through mutation because of the mutagen in his own blood. This gave Donnie interesting new abilities such as the ability to shape-shift and split himself into two, with the other "him" being a remote-control clone. By the end of volume 3 though, his body finally started to reject the mutation because his mutant healing factor had been regenerating his broken body all that time, even completely regrowing his shell (which had been crushed and destroyed in the beginning of volume 3), and with Baxter Stockman's help he found a way to fully separate himself from the mutated metal to prevent the rejection from killing him. So yes, mutations just as weird or weirder have been written over the years. :)
