Failed experiments are usually disposed of in a correct manner, but sometimes Darwin's interns have been known to flush failures down the toilet, this practice has inadvertently led to the formation of a new mutant that has grown from the mixture of chemicals.
- Obviously a reference to Master Splinter, the bipedal rat and mentor of the Teenage Mutant Ninja Turtles franchise.
- The Bronze version seems to have Akuma's clothes from the Street Fighter video game.
- All elite versions have a reference to Illidan Stormrage, from Warcraft. Bronze has blindness, Silver has its 'tattoos' and gold is dark and the 'tattoos' are shining green, like the transformation of the elf.
