Bambi has everything prepared for the final battle and strikes into the final door. Once he got in, he though he was in a red world, but then he realized, he actually is. He saw lots of flames in the platform. He saw him and tried punching him but it results on Lunatic Dave blocking his punch and throws him in the ground, they get already into a fight by arguing. However, Lunatic Dave says this line "You're a reason WHY in the world would you try killing me two times in a row and everything else!" but Bambi OUTSMARTS him by saying "And YOU'RE the reason why you damaged an 17 year old guy very badly after listening to an ANOTHER FUCKING SEQUEL OF YOUR MARATHON!" but then, Lunatic Dave snaps and begins transforming. He is not transforming to any phase. He begins to grow fire in the wheelchair, and basically starts to get an sword. Which that is known that his new form is the empowered form. And the battle beggined just in time.
