They both have the same personality except that silly billy is a a bit duller in color, his hair is messier, and he has rips in his clothes, adding to his look.

•Appearance: Keith is a tall version of Boyfriend with a dark shade over his eyes, yellow teeth, and torn and ragged clothes. His prohibition sign is now a circle with an X and most of his colors are faded. His shoelaces are loose and he also wears a red shirt under the white t-shirt, as well as a completely red hat.

•Trivia: In Hit Single, Yourself is based off Divide's ideas. However, his design is based off Lookalike's. Herself's spirit is inside Yourself's microphone. It is unknown how this happened. Herself briefly appears in a flash during the lyrics part and she can also be heard singing with Yourself.

While unshrinking, Keith mimics Boyfriend's "Oh yeah, ah-ha!" that he did during Soul Robotnik's section of Triple Trouble from Vs. Sonic.Exe, the mod where Yourself was meant to debut in. The purple hue Keith summons during the lyrical portion of Silly Billy isn't just something for the cutscene, as the change also sticks around for the last part of the song.
