Final Boom

The Final Boom is an event in which Kyle releases an explosion so large it consumes the entire universe with milliseconds. Kyle would only ever decide to use this if he is near death as using it will also kill him, It can kill most beings but some "godly" ones are able to survive although this can be stopped if used at point-blank range of said after mentioned "godly" beings.

Examples
Kyle used the final boom to kill Mrs Madine during the "Kyle kills the entire Clydeview universe" scenario. Him doing this also took himself along with the rest of the universe with him.

Kyle uses a "Contained Final Boom" when going up against "%^7685&556h%*^' in the last leg of The Final Battle.

Contained Final Boom
In the Final Battle Kyle uses a "Contained Final Boom" which did not consume the universe. It instead only spread a few miles before being stopped by Kyle himself willingly.
