"Unknown guy is out! Peace!" — Unknown guy[source]
Unknown guy is a character who appears in "Unfair Science Fair Redux (Another Story)". He is seen walking towards Candace, Stacy and Jeremy. He strangely walks away after saying he is Unknown guy and he actually has been avoiding Candace. Candace and her friends just look in confusion. His quote, "Unknown Guy is out, peace!" becomes a running gag after this. Because he doesn't appear in later episodes, it could actually be assumed that he's avoiding Candace and her antics. He thinks his plan of avoiding Candace appears to be working. He also appears in the Mix and Mingle Machine. He appeared dancing in the background in "Carpe Diem".
