G4 Underground premiered last night on -- you guessed it -- G4. The show is a news magazine covering odd, extreme, illegal, and underground topics. Last night's premiere focused on real-life super heroes (and amateur porn). The super hero segment looked at two gents who dress up in masks and tights in real-life, including one -- Dark Guardian -- who patrols the streets of New York City. Really.

If you missed it, G4 Underground reairs tonight at 9 PM EST.
