2k3 Karai meets 2k12 Karai
 

It would be kind of interesting on how they would interact, their personalities are almost opposites, I kind of see a Raph and Mikey relationship

Karai is far more skilled than her teenage counterpart.

I think 2k3 Karai is better in skill and mentally.. And probably they would be enemies cause Shredder must conquer all the multiverse hahahaha

I don't think 2012 Karai would like Loyal 2003 Karai very much XD

she'd probably think she's a stick in the mud :D

Oh they would not get along well, teen Karai would want out once she got to knew 2003 Karai :P

However, I'd love to hear what they think of Leo of both worlds :D

2K12 Karai loves doing things her way (she likes being evil). I don't think she'd bond with her 2K3 counterpart very well.
