>Dragonite's thing of being some fairytale-like creature is boosted by changing in a way that it unironically makes it look like a fairy type by regaining traits of its previous, more mystic looking stage. Overall a pretty megaevolution
>Victreebel's thing of being a giant pitcher plant that lures you with nectar to trap and digest you is boosted by producing so much digestive fluid it overflows with concrete-melting poison it can barely contain, so its sweet scent lures you just so it can puke acid into you. Overall a goofy megaevolution
>Hawlucha's thing of being a bird luchador is boosted by gaining a falconry hood that resembles a more elaborated luchador mask with both the mask and its plumage becoming more flamboyant and flashy like a real star. Overall a cool megaevolution
So far all new megas expand upon the original themes of the species, can be pretty, goofy or cool and none of them just gain spikier and edgier looks to sell you the idea of a power up.
Give me a good reason to still pretend to dislike megaevolution.
