HEY my name is Jobby and I make comedic, fast-paced toy reviews. I usually review Masterpiece / Third Party Transformers, Japanese import action figures (Bandai, Takara Tomy, Good Smile Company, etc), and figures from anime.
I dont know why its a debate, but allow me to clarify, as you asked for us to. Frenzy is the red one, Rumble is the blue one. It was stated in the G1 show/movie. Because Soundwave commands his Minicons to eject by saying their names and telling them to, so anytime he'd say "Rumble, eject", its the blue one that pops out.
The only reason why I don’t really like this Megatron figure is because it transforms into a gun and I’m pretty sure many fans wanted to transform into a tank
