>Mega Exeggutor's heads split back into six and start orbiting the trunk psychically, the legs plant themselves in the ground and it gains a shitload of def/spdef

>Mega Machamp takes his belt off and bulks the fuck up so much that it has to lean forward and support itself with two of its longer arms, gets huge power
>Mega Slowbro's tail shell grows so big it covers his entire back, the teeth digging into its head and forcing it back into a bipedal stance like a turtle/hermit crab
>Mega Magnezone splits back into three Mega Magnemites, the two smaller eyes becoming orbiting spheres attached to the larger middle one with electric currents
>Mega Dodrio's three heads mega evolve into three different things (one red-feathered and angry, one blue-feathered and meditative and one yellow-feathered and prideful) and it gains wings, gets an ability that grants it the effects of three different abilities at once (Intimidate/Inner Focus/Guts?)
>Mega Gengar's shadow elongates and can be controlled independently, giving it an automatic Double Team boost and a clone of Mega Kangaskhan's ability
>Mega Omastar's shell splits down the middle revealing yellow-tipped blue fleshy spikes, it stops being slow and heavy and becomes a furious blue squid monster
>Mega Girafarig's back half becomes fully developed, gains shadowy-looking arms and a more defined tail-head that arcs over its body
>Mega Mantine turns into a manta ray jet fighter and gets two Mega Remoraids on its wings as missile launchers
