I saw a random ad while browsing Facebook, and was like wait, there's five turtles in that picture. Then I realized one was wearing a yellow mask.
I went and looked it up and apparently her name is Jennika, she wields claws like Vega from Street Fighter, and is a super serious outcast member of the team who used to be Shredder's second-in-command.
Reminds me a LOT of this guy from Mighty Morphin Power Rangers.
Has the "used to work for the villain" and "slightly different vibe" and "late member of the team" boxes all checked.
Seems cool to me, and I am normally very skeptical of added characters to established teams like this. Maybe she'll end up catching on?
What do you think?
