Sentinel Necronoid

Desperate to win, Necronoid and Sentinel combined into a single monstrous Bakugan. With each member hating the other and wanting to be stronger, both keep giving more energy than the other, making this fusion stronger every second. The downside to this is that at some point the energy will overload, meaning this fusion cannot be used for too long or its head will explode. (And that's the LEAST damaging thing that it could cause)
