- You know it!!!! Boo-yah ska-doo!!!!
- --Yellow Cyborg talking to Robin
While Robin was interrogating Cyborg in order to isolate his best personality from the rest, he shoots Cyborg with a Mysterious Prism loaded gun resulting in five different Cyborgs and Yellow Cyborg was amongst them. Robin asks him what's important in a battle between strength and strategy. Yellow Cyborg yells they're both great. Robin figures out he's Cyborg's enthusiasm and takes him out because of his loud voice.
Yellow Cyborg looks exactly like regular Cyborg except the transparent modules on his head and arms are yellow, and the cybernatic eye is orange.
Yellow Cyborg is very enthusiastic. He shows great energy in his actions and voice. He yells all the time, and is very cheerful in nature.
