Like many other Cybertronians exposed to Terran forms of music, Treblecharger is wild about it. Constantly playing a wide variety of music types from every corner of the Earth, usually too loud for his companions. He'd rather be out at a human beach party than anything else. He is loud and boisterous, much like Noisemaker, and also like Noisemaker, quite hard to keep quiet at times. Treblecharger seems to live off of music, and is known to play music during combat, usually hard rock. He will often play music that reflects his mood, however he is rarely anything but happy. He has an annoying tendency to play the same song dozens of times over before switching to another track.

Treblecharger can receive, transmit, decode, and encode almost any kind of radio transmission, from a very large range. His specialty is interception, capable of jamming, rerouting, or simply listening in on any transmission he can detect. He is more of a mobile communications relay station that anything else. In robot mode, he carries a sonic blaster, capable of causing serious damage on a high setting, even small earthquakes. In vehicle mode, he can reach a top speed of up to 170 kph.
