He had several important appearances in season 2, most notably in "Blaster Blues", when Spike and Carly brought Blaster to a concert because he loved music. Blaster decided to share his music by transmitting the show to the other Autobots but drove everyone but Cosmos and Jazz, who liked his taste in music, crazy also because the music was so loud they were unable to respond to a Decepticon attack as they got away with stealing a powerful decoder. Blaster and Cosmos went looking for the Decepticon in space then as luck would have it they found something on the moon which turned out to be a Decepticon hideout. Blaster and Cosmos listen in on their plans to conquer the Earth but they ended up getting captured by Astrotrain when they got discovered by Megatron. After they got captured, Megatron decided to use Blaster as a transcrambler with Cosmos being used as a power booster for their device which could foul up Earth commutation systems. Blaster, who wanted to stop Megatron's plan and to redeem himself from before, tipped the other Autobots the Decepticons location by transmitting his music when Megatron ransomed the humans into giving all their energy reverses. Blaster ejected some feedback to overload the Decpeticons machine with Cosmos offering a power boost to destroy it, after Megatron and Astrotrain left base to confront Omega Supreme, Powerglide, Optimus Prime, Spike and Carly when they arrived to stop them and to rescue them, which stop their plans.
