I think Karai is probably the fan-favorite secondary character in the TMNT franchise. In the toy world, her figures are always in high demand and fetch a high price in the collector circuits. I don't really know much about her beyond that fact that she is often labelled as the daughter of Shredder and usually has a vampiric look to her. Of course, she is tweaked and changed in every incarnation of TMNT so I never know what to expect. In the current Teenage Mutant Ninja Turtles cartoon on Nickelodeon, Karai is a young girl who was indeed raised by Shredder (via kidnapping), but is actually the biological daughter of Hamato Yoshi, a wise sensei who is mutated into the rat Splinter. When her true origins are revealed to her, she has to reconcile her life of lies and evil with her newfound family. She reminds me a lot of Cass Cain in the Batman Universe. Last year we received a figure of Karai in her serpent incarnation which was cool and unexpected, but this is the one we've been waiting for. Let's check her out!
Karai comes with a small face mask that is held in place with her hair.
Her sword is also removable from its scabbard.
Karai's articulation is decent, but clearly intended for kids and not collectors. She has no elbow, wrist, or ankle articulation. And her neck joint could easily be a ball joint, but instead it's just a side-to-side swivel.
Time for some Comparison Pics!
Here she is with last year's Serpent Karai figure.
