Breakdown is a character from the Transformers franchise (c. Hasbro), first released to the public in 1985 after the license to Scramble City, a toy series of combining robots, was given to them by Takara Tomy. His first appearance in any cartoon media was in the episode'The Key to Vector Sigma, Part 1' aired on the 25th of November, 1985 in America, the 2nd of May in 1986 for Japan (yes, despite the fact that the characters were greated and designed in Japan), with unknown air dates for other localizations.
The first line Breakdown ever says is "I'm... I'm Breakdown. I'll obey too." voiced by Jack Angel, who is known for playing the role of Zarkon in the original Voltron series. For english releases, every line Breakdown says after this is said by Alan Oppenheimer, best known for playing Skeletor in He-Man.
