Illustrious: You can have two characters that are bonded to a legendary Pokemon, and any ammount of other characters.
Hadesiro: Nya, the Lavender Lab is run by the Olympus company, since Team Rocket has been disbanded in the games. They just recieved their information on cloning technology and Mewtwo from former members of Team Rocket. Other than that, I'll accept your explaination, you can have the two characters connected to Reshiram and Zerkrom as long as you can come up with a way for the Olympus company to get Kyurem's DNA without having Kyurem directly under their control. Also, a reason why doing that would've benefited the Olympus company would be nice.
... hm... if we're going by Kyurem being a reanimated corpse, I might have to mark it as an unavailable legendary.
JakkuEbansu: Accepted. :3 Sorry for switching on you, I forgot about the signature thing myself until I read through my rules agein.
