Okay, so in the S2 forums, the devs said that if there was going to be a S3, which is now confirmed, 1 of the characters was going to be a sibling of 1 of the S2 characters. Hmmm…
Any ideas?
I just wanted to remind you guys of this little tidbit for the fun of guessing. 
I’m pretty sure that they stated the sibling is NOT related to TJ, Maya, or Riptor. Maybe Cinder, too. I forget.
My guess goes to a relative of Hisako’s. She seems pretty popular, so I’m sure a family member of hers would also be well-received. Hisako is a bit chaotic and revenge driven, so maybe a counter-part that’s calmer and more orderly than her trying to awaken her spirit so they can fight together. What weapon would they use, though?
If not that, then maybe Kan-Ra’s brother/sister, also trying to stop his reign of terror…or, possibly, protecting him from Gargos, since he did kinda open the portal. Gargos must be pretty excited to give Kan-Ra a handshake (read: horrible pummeling).
We def need a Samurai character. Probably the best way to achieve it. I sort of wished it was Omen who would inhabit a Samurai armor and bring it to life if they made him a “real boy.”
Maybe Eagle (Thunder’s brother)?
Season 2 characters. Plus, we need to work out the Fulgore situation first…
I really like the idea of the character being Cinders sibling.
@Sciencejoe, I think you might be on to something actually. What if Kim Wu is the descendant of Hisako? Now, there’s a great thing to go on. 
Just for the record, Adam said he had an idea for a character like this. It wasn’t actually confirmed they would be included, so they may or may not make it in the game.
Either Hisako, Cinder, or Kan-Ra for that particular case
