According to Dan Fleming in Powerplay: toys as popular culture, Blaster and his cassettes represents a guardian of more primitive heroes, as well as the hidden power of technology.
Rewind first appeared as one of Blaster's warriors in The Transformers the Movie, where he defended Blaster's communications tower from the Decepticon cassettes.
His most prominent role came in the episode, "Forever is A Long Time Coming". In this episode, Rewind, Blaster, Ramhorn, Blurr and Wreck-Gar are transported to Cybertron's past via a Quintesson time window. Rewind's information allows the Autobots to identify where they were in the timeline. He aided the prehistoric Autobots in defeating the Guardian Robots, thus keeping the original timeline intact. In this episode Rewind shows a love for exact timetables, when Blaster remarks that the asteroid they were going to investigate had been there for millions of years Rewind comes up with a date to last year, month,day, hour, and minute.
In episode 78, "Madman's Paradise", Spike and Carly hosted a banquet for a visiting ambassador. Daniel got bored and wandered off. Grimlock followed him, and they fell into a lost chamber where Quintessons banished their criminals to other dimensions. They slipped through to the sorcerous other-dimensional realm of Menonia, and were tricked into fighting on the Red Wizard's side, only to find out that he was the Quintesson criminal, who overthrew the Golden One. Ultra Magnus, Blaster, Eject, Rewind, Ramhorn, and Steeljaw followed, thanks to Rewind deciphering the ancient writing on the walls, and using Blaster's amplification, they help the Golden One defeat the Red Wizard. With the help of Perceptor, the Autobots and Daniel are returned to Cybertron.
