Tamers12345

Tamers12345 is the sole creator of the newest episodes of Sonic Underground. He appears alongside the original cast, and is a close associate of Bartleby. He is, in fact, the biggest Sonic Underground fan and has effectively revived the series through his labor. He has overwhelming power, destroying a meteor before it crashed into the Earth (Fall of The Sun, Our Darkest Moment) while proclaiming the others' fear of the collision as "silly".

Appearance
Tamers12345 wears a Bartleby costume that he received from his friends during his Birthday Bash, replacing his older Sonic outfit. The costume, according to his Q&A Videos, consists of a set of boxes that he received from his local Target.
