The Beast (inFamous)

John White also known as The Beast is an antagonistic entity of the inFAMOUS seires. He has the power to awaken conduits and cure them of the plague but at the cost of killing all of the humans in the nearby area.

inFAMOUS
John White appears assisting Cole in the last few missions of the game, after the Ray Sphere is destroyed John is sucked into it and dissapears. The alternate future version of The Beat is shown in Kessler's future vision of how he wrecked the world. This is the very reason he travels back in time to fix this.

inFAMOUS 2
The Beast is the main antagonist of inFamous 2. His true identity is revealed to be John White, whom Cole helped out in the first game trying to destroy the Ray Sphere. It turns out that the energy in the Ray Sphere took over John's body after he is sucked into a vortex of it. In the end, The Beast is defeated when Cole uses the Ray Field Inhibitor, killing the Beast, himself and every other Conduit.

Evil Ending
Cole joins The Beast and Kuo and works to awaken the conduits thus curing them of the plague. The Beast gets tired after Cole kills Nix and Zeke so The Beast gives Cole his powers and lets him complete the mission to awaken the conduits and cure them of the plague, while destroying all the life that does not have the conduit gene.

Possible discrepancy - A Second Beast?
Kessler's use of time-travel raises the question of whether John White was also the Beast of his original timeline. John White in the first game was transformed by events whose frame was shaped by Kessler's meddling in the new timeline. While it is possible the John White of the original timeline (if there was one, since Kessler had a century to alter known history) was the man who became the Beast through existing Ray Sphere experiments, the possibilities exist that the Beast of the original timeline was never (or has yet to be) transformed, or even that the original Beast could one day duplicate Kessler's one-way time door. These questions cannot be answered unless a third game emerges, if in fact any of these questions are part of its premise.
