Always really liked Mona. I wish they would do her on the new show; I think it would be super cool to have her be semi-reoccurring instead of just a one shot. I tried to keep her as close to the style of the new show as I felt comfortable with; I feel like no way is nickelodeon comfortable with her being a naked teenage girl (lizard, whatever) so she is clothed.
I grew up with the eighties series and there was seriously a dearth of female characters, which made it somewhat less fun to be a girl and collect all the toys (even the ones with the plastic strips that make them speak in demon voices; yeah, I’m that old). I hope there’s little girls out there watching the new one every saturday morning, too, and it would be cool if they could have a girl mutant (who isn’t a ninja or a turtle, we know how that turned out) to put in their turtle print draw string bag with the blimp— I mean… um. Ahem.
I also think she would be great for Raphael, who in this series I am not super digging (even though Astin is doing a great job, FWIW) even though he is usually my second fave (DAAAAAAAAAAAMN). I feel like he needs a good foil to bring him up short / engage him in banter / etc. I know that’s supposed to be Leo, but I dunno, just not feeling like they have that going on. Whatever, YMMV.
Not to mention that she would be a super great shout out to old fans! She has been redesigned by fans so many times, and is well remembered by a lot of people, even though she only had one ep.
REGARDLESS, haha, tl:dr turtles always need moar mona.
