Daisy and Freida are big Backstreet Boys fans.
Replikon's only appearance in the whole series.
Replikon is based on the Static comics character, Snakefingers, who is a hitman whose fingers turn into snakes, and bite it's prey. Snakefingers was also a shape-shifter. He was hired to kill Static, but Static realized that his name, Snakefingers, means that he's like a snake, so he pours freezing cold water on Snakefingers, because snakes are cold-blooded, so they must stay in high temperatures. Snakefingers also only appeared once in Static comics.
