You would have been so boss watching web world as a kid. I thought that he was becoming Megatron again.
If you set aside your love for Megatron, which is understandable (who doesn't love guns and robots?!), you may be able to see that Galvatron is really his own character and the only thing relating him to Megatron in any way is his origin, which doesn't change much, as he is practically completely different /unique in terms of mind.
I would treat Galvatron as a different character, if you wanted to appreciate him more.
