Teddy Harmony, aka Tiberius Fredricks, is a human bartender, residing in Shortwave City, though was originally from Cucina City. One of his fathers, Enzo Cobretti, is a Trivial member running Cucina City. However, Enzo utilized Teddy's accident that caused him to lose a leg as a means to get more money. He despised his father for that, moving to Shockwave City where he fell in love with Sterling and befriended Dot and Quill. While in Shockwave City, he started owning his own bar called Strawberry Street.

As a character, Teddy is flirtatiously charming, typically catching people off their guard with any quick quips. Yet he's sort of a gentle giant, in a way, having a more calmed down, caring side to him past the flirtatious facade. However, he has a great disdain to those who are overly greedy or just downright creepy. And he is more than willing to stand in front of those who are afraid to stand up for themselves.

In the band, he is the guitarist but would occasionally sing for a bit in a song himself. Again, having a singing demo is preferred, yet not mandatory. He is going to sing less than Dot and Sterling, but there will be moments where he'll sing. He has a baritone vocal range.
