Why are you assuming that every instance of Existence Erasure One does is completely different when it's been made clear that it's the same ability under the basis that things are being erased?
Because each instance had a different setup and ending. For the cage and alien, they had a targeting/telekinesis (idk what to call the blue thing on the cage) with One looking straight at them, changed color (flash of white and hue shift) with an accompanying sound as they fade away. While for the contestants, a tornado swirled around One as she charged up with an anticlimactic nothing as the contestants just disappear, theres no telekinesis, no sound, no color shift, just, gone. Thats why I believed the two to be different types of EE rather than the same, but I’ll concede. She still has EE and is more likely to use it than Dimentio and any of his base hax.
The thing is, she has Two's powers which have the ability to absorb the powers of those user kills, which has been something One has observed before. Thus, by killing Dimentio, she would already gain his power anyway without having to stare at him, so it would still be within the lines of her character and goal. Given how her Existence Erasure is history-based while Super Dimentio's resistance to EE is only the regular kind, he would still be affected by it anyways. As for Luigi, he pretty much broke out of being brainwashed after Dimentio died, and also One can just erase him due to his lack of resistance to EE which would in turn cause the Chaos Heart to disappear.
I thought it only absorbed TPoT? If Dimentio is erased from all of history, wouldn’t his powers also just get erased? Also would that Power Absorb be enough to take the Chaos Hearts infinite power?
Pretty sure the Chaos Heart would disappear right after it gets spit out of the body, as the body was the only thing keeping Luigi and the Chaos Heart connected, as seen with the fact that Luigi doesn’t disappear after the Chaos Heart is banished.
As for Luigi, he pretty much broke out of being brainwashed after Dimentio died, and also One can just erase him due to his lack of resistance to EE which would in turn cause the Chaos Heart to disappear.
Yes but I was wondering if Luigi would still be brainwashed since Dimentio brainwashed him, and since Dimentio would be erased from history, would he be Mr. L or would he be Luigi? Also why would it only be Dimentio and not Super Dimentio?
Would One EE before the Void destroys everything? Going off of your list, she’d laser first, but would she keep shooting lasers or swap to EE? Or would she time BFR first (she used it for Pencil, rather than a test of her power)? If she keeps shooting lasers, Dimentio boasts about his power and L-Power the Void, causing it to quickly destroy all of existence. If she swaps to EE, then Dimentio is gone with the Void possibly having destroyed all of existence already (Dimentio helped the heroes revive the Sammer’s Kingdom’s Pure Heart, without it Count Bleck would have destroyed everything). If she time BFR’s first then Dimentio uses Dimension D to get back/have the Void attack One.
Also would Super Dimentio’s platforms do anything here?
They spawn when Super Dimentio is formed, and
disappear when Count Bleck is defeated and the Chaos Heart leaves him. But as James_Plays_4_Games said, this might be something specific to Castle Bleck, as it is located in the Void, which means these platforms, and by extension the castle itself, might conform to the Chaos Heart and it’s host.
