Shadow Ethan

"'It's the red, beady eyes that are a dead giveaway for the evil fellas.'                                                         -- Spongebob, Nicktoons: Attack of the Toybots"

Origin
Shadow Man was forged in the darkness that was Jerry the dummy's spit. Ethan1 was so curious to touch the puppet's mysterious black spit, even though he was advised not to. Stupidly, he did, and darkness formed around him. He was overtaken by the shadows, and formed into an evil figure with pitch black covering his formerly normal features, except for his glowing red eyes. After a few days, he came back, and he attacked, and nearly killed, Jimbo and Vis. The subspace abandoned him, and Ethan1 felt very guilty for attacking his friends. He later committed suicide because of his actions.

The Shadow Man's hosts
The Subspace Shadow, as it is also called, has had more hosts than Ethan1. These people include the following: Ethan2, a random wolf with rabies, and Serge. Also note that while Serge was possessed by the shadow, he battled with Jay, Storm, and others, and lost. The fiend died because of this. ''You could say he got clockworked up. ''Get out of here, Ethan2! Gah.

A Comeback
Ethan2's former archnemesis, The Shadow Man, was actually Ethan1 possessed by the subspace, to Ethan2 and Jay's surprise. He was defeated by Jay warping the subspace for his own.
