Biiionic Bionic Six (oo oo oooo oo oo)
I grew up with the 80's DIC/Marvel Comics Care Bears where most of them were androgynous and just used masculine pronouns as a default. Might change that to "they/them" the description if it causes too much confusion.
This card is numbered 17 but the first card was 0, so this is the 18th card.
That’s a pretty good, but I think in the continuity of TMNT, Splinter had no idea how the Turtles personalities would’ve developed when he named them. Unless he named them later in life? Who knows? Great observation nonetheless.
