Ime including the time it takes from the void to open, to the entity to reach the void portal, then I counted how long it took to destroy him, and by my calculation, M2 is not going to sit over a void portal or even allow himself to be moved onto it in the first place and if he did it for a laugh, he would fly away again to escape any damage.
He would just wipe Ganons mind of everything anyway, then use his TK to make Ganon dance like a whelp.
