Yeah I love Optimus Prime. He is probably one of the strongest 'fatherly' characters from those 1980's toons that helped shape me. Yeah, Thundercats had Jaga and the Turtles had Splinter... but these guys were more advisors/ elders than leaders. His toy was great and epic all at the same time, pretty simple transformation and great play value with a base, trailer, seperate car (roller) and repair bay.

The thing that ruined Prime was his botched death/ resurrection. He was succeeded by first Ultra Magnus, who was almost a coward on Starscreams scale and then Rodimus Prime, who was so unsure about himself it wasn't funny. OP had his faults... but next to those that came after him he just seemed too perfect.
