What Pokemon would you like a Mega Evolution for in X/Y?

[SirBlaziken]

A

Mega Tyranitar
Ability: Sturdy or sand stream

[WeegeetheKid]

I wanna see a mega typhlosion.
type: fire/ground (because volcanoes)
ability: flash fire

[WeegeetheKid]

In fact, I'm thinking all the fully evolved starters should have megas.
in other words:
(kanto's are confirmed)
meganium
typhlosion
feraligatr
swampert
blaziken (confirmed)
sceptile
torterra
empoleon
infernape
emboar
serperior
samurott

I think these Pokemon would be cool to see:

Banette (Ghost/Dark)- Becomes significantly larger and more sinister looking looking more like a voodoo doll with a stitched mouth instead of a zipper
Cacturne- Grows larger and an extra set of larger lower arms that are extremely spiky clubs

Hydreigon: Grows another three heads on its body. The two heads on its hands are bigger and each head has pointy teeth

Golem (Rock/Steel): Grows even larger and bulkier with metal plates on its body

Omigosh, a mega swampert would just make the game for me!

[Red Snorlax]

Mega-Snorlax or we riot.

[Sir Trae]

I would like to see a Mega-Nidoking/Nidoqueen. The two have great movepools, but are severely handicapped by their somewhat low stats. I don't know what would be a good ability for them would be though. Perhaps an form of poison point that can inflict badly poisoned? This seems like it would be over powered. Anyone else have any ideas?

[Richard and Blaziken]

Sheer Force is much better for both of them on most sets.

[Ya-Yah]

Do you think there will be any mega legendaries? Or is mega-ness already suggested by the fact that they are legendary in the first place?

[Hitmonchu]

Victreebell, that pokemon is godawful.
