Thunder Mothra

Space Mecha Godzilla (saw a fan art of that once it was actually nice i.e. not a rehashed reguler Mecha Godzilla that was put in space).

Armored Rodan (like Armored Mothra)

Uparmored Godzilla. Rather then armored Mothra, just give him armor that boosts his attack and defense. Could have weapons on it has well. There was a toyline in the 90s that did that. There is a page on this wiki with pics of them.

Solar radiation Godzilla since the sun gives off radiation what would happen Godzilla got a good dose of it?

And playing on a film storyline in Godzilla vs. Megaguirus it was stated the Japanese had stated working on plasma power but stopped when they found out Godzilla liked plasma has well. What would happen if they didn't stop and they replaced all the nuclear power plants with plasma plants? Would he get new powers? Would his color change? Would his beam change?
