"How da—"
Before Fantasia's avatar could even complete her mockery of calling them all mortals and how they were beneath her, Fantasia's avatar dissipated into dust as her existence was erased by Alister's Unpredictable Chaos Authority.
Alister literally spawn-killed her and he didn't even hesitate to kill her as soon as she descended on the Magic Fantasy World. He already knew what Fantasia's avatar was going to say and he knew that it was all her trash-talking about how they were beneath her status as a goddess yet they dared to go against her.
Rather than having to put up with that bullshit like in the previous timelines, Alister didn't even need to let Fantasia's avatar do her thing since she was of no use to him.
In the previous timeline, Alister let Fantasia show off her power so that the powerhouses of the Magic Fantasy World would know that she wasn't fake and her power was the epitome of a Demigod who also had access to divinity.
