I grew up on Galvatron as a kid. My first taste of transformers were the 86 cast. Always thought they were cooler. I didn't really get into Megatron until I got season 2 dvd set in full and saw all the episodes I missed as a kid. He grew on me, but nothing beats nutty Galvatron.
He Killed Magnus for sure. The Junkions brought him back to life. Galavtron "First Prime, then Magnus now you, too bad you autobots die so easily" or something like that. We were left with the impression that he Killed Magnus in the movie. Even though he came back I count that as 1 for Galvy.
