The Loud Mutants: Lisa Loud

Shredder: You insolent brat! I created you, therefore you shall obey my commands, for I am your master!
Lisa: Actually, you were merely the provider of the mutagenetic substance which has altered the DNA of myself and my siblings, and I was already in existence before my exposure to the mutagen, Ergo, you are not my creator. And even if I had been a product of your creation, it would be a poor career choice to serve a clearly megalomaniacal and sociopathic individual such as yourself.
Shredder: AAAAAAGGGHH!!!!

Lisa was engaging in studying their pet hamster Geo, when she was mutated by the ooze in the water! However, she is unfazed with her transformation, having already dabbled into such basic chemistry in her previous studies. She's sure she can whip up an anti-mutagen to reverse the effect. That is, if she can get past those Foot Soldiers first...
