In the latest installment of CurtainsAreOnFire's Mortal Kombat Secret Character Tryouts video series, the Angry Birds get angrier, Paperboy delivers carnage, and Dr. Robotnik finally creates an obstacle course capable of murder.

Dr. Robotnik generally falls into the Bowser category of video game villains. He really wants to be evil, but he's kept from reaching his true potential due to an ESRB system that won't let him murder fuzzy animals. He has potential, but it remains perpetually untapped.

But in the realm of machinima, anything is possible. Even the Fatality Zone.
