Hmm interesting so maybe the sun would force the hybrid to be an oozaru and the full moon forces it to be a normal saiyan. Since kryptonian gets their powers from the sun while saiyans become an oozaru get empowered by the full moon blutz wave. But a hybrid gets stuck and cant get stronger with each fight because they are always empowered in the sun unless they fight during a full moon otherwise zenkai boost is impossible. Maybe frequent exposure to kryptonite then getting beaten up is the only way to get stronger.... Interesting combo that for sure.
