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

[Richard and Blaziken]

So after thinking about it a lot, there are a few Pokemon I'd like Mega Evolutions for, but I'd also like to know what you think! Post which Pokemon you'd like to see Mega Evos for, their possible designs, abilities, type, stat buffs, new moves for the Pokemon, and reason why you think they deserve one! Here's my list:

Mega Vileplume
Ability: Regenerator
New stats: 130 / 70 / 90 / 110 / 90 / 50
New Moves: Leech Seed, Toxic Spikes

Vileplume has always been among my favorite Grass and Poison types, but it suffers from a severe case of being outclassed. With 130/90/90 defenses, this would make for an interesting defensive Pokemon, with Regenerator and Leech Seed setting it apart from Roserade in the role of Toxic Spiker. If you don't need T-Spikes, this would have a decent Sp. Attack stat to utilize, but retains the shallow offensive movepool of Giga Drain, Sludge Bomb / Sludge Wave and HP Fire/Ice. In terms of design, I'd say have the Rafflesia flower even bigger, possibly having the leaves drooping so far down that it uses them as appendages.

Mega Machamp
Ability: No Guard
New stats: 125 / 130 / 80 / 40 / 85 / 80
New Moves: Drain Punch

Machamp has been severely outclassed in most things by Conkeldurr, and this form of Mega Machamp would help bring things back for Machamp. DynamicPunch would still be the main sell here, coming off the unchanged base 130 Attack. Drain Punch would allow for healing, which is surprisingly a move that Machamp currently doesn't have. As for the design, I'd like to see a much bigger championship belt, maybe some extra arms, I don't even know.

Mega Gengar
Ability: Levitate
New type: Ghost / Dark
New stats: 60 / 65 / 60 / 135 / 65 / 110
New moves: Can't think of any that it needs that make sense

Basically just changing Gengar into Ghost/Dark really turns it into an entirely new Pokemon. It wouldn't really utilize the Dark STAB, but lack of any weaknesses (unless Fairy hits this Super Effectively, which I'm hoping for) really aids Gengar, especially vs. Psychic types. Not much else to say about it, aside from lowering Sp. Defense to ensure that neutral STAB attacks really hurt, so it can't really wall forever. As for the design, I'd really just like to see a return to the days of Gengar being black instead of purple. Look how awesome this is:

So what do you all hope for?

Mega Meganium

Ability: Serene Grace
Stats: 100/80/100/85/100/80
Retype: Grass/Dragon (Dragon is more of a Dinosaur type anyway...)
New moves: Dragon Pulse, Dragon Breath, Outrage

Serene Grace Meganium would be Epic, to put it simply. Body Slam & Dragon breath would be staples on Physical & Special sets respectively, and then possibilities such as Dual screens, or a cheesy Ancientpower hax set. I'd just live to see my Dino get more use

[Wolstenholme]

Mega Hydreigon...

- I wouldn't be able to think of abilities or anything but I have a fantastic idea about how it should look! (I might try spriting it tomorrow.)

[NTN]

MegaShuckle. And an evolution with higher defenses and kick-ass HP.

[Richard and Blaziken]

Mega Hydreigon...

If they made one, I could only see it having Levitate, as they typically don't give things with Levitate multiple abilities, Bronzong being the only exception. Still, Mega Hydreigon would be interesting.

[Liam]

Mega Quagsire even though he's the best Pokemon already.

[Alpha Fenrir]

Yes, Mega Hydreigon please! Just make sure we don't have to face it in-game... Ouch.

There are a number of pokemon which I feel that, even if they don't get outright evolutions (or wouldn't really suit true evolutions), they should at least have mega evolutions. I'll just list a couple here...

Mega Mightyena
Ability: Moxie/?
New Stats: 80/115/80/30/70/95
Type: Dark
New Moves: Agility
Mightyena has always been considerably outclassed. It's attack and speed have never really represented the design, and whilst Intimidate was useful that was where it's advantages ended. Mightyena isn't, to the best of my knowledge (I'm not a wizz on competitive play, so forgive me if I have got this wrong), particularly useful even in lower tiers, which is a shame because it has a decent movepool and a great design.
The increase in attack and speed is essential for a boost in usefulness. Agility could be added to it's movepool to allow it to see some action, and the slight increase in it's defensive stats should reflect upon the extra bulk it's new design should show (bigger wolf/hyena. I'm no good at designs so I wouldn't know what else to do). It's ability should either be Moxie, allowing for  sweeps in certain situations, or a new one which boosts the power of biting moves by 1.5x to 2x (or does that already exist?). Crunch with a base power of 160 or 240 anyone?

Other ones which spring to mind are Seviper and Zangoose, but I'm not entirely certain what the boosts would be for them... And the Fossil pokemon.

[Wolstenholme]

Are we ignoring the possibility of Mega Gardevoir?

[Richard and Blaziken]

Are we ignoring the possibility of Mega Gardevoir?

Mega Gardevoir would be nice. Gardevoir has such low stats in nearly everything, it definitely needs a boost.

[MonsterMon64]

I said it in an earlier thread, but Mega Hariyama would be nice. I think the biggest change it needs is an increase in both defensive stats, since it has a decent Attack to work with and plenty of HP. I wouldn't know what else to give it, though.

Not getting my hopes up for it, but it'd be nice if Raichu could Mega-evolve, too. Mainly I'm sick of everyone using Pikachu over Raichu because of that dang-blasted Light Ball.

[Angelic Lapras King]

MegaLapras.

You know me. ;P But also;

MegaTyranitar (Something badass and scary looking)
MegaYanmega (For all sorts of Mega things, like MegaYanmega used Megahorn, etc.)
MegaPachirisu (Speed demon)
MegaMantine (Thought they were pretty cool in GSC)
MegaHo-oh and MegaLugia

[Spriter]

MegaCorsola
Ability: Magic Guard
Stats: 104 / 76 / 110 / 96 / 114 / 50
Moves: Aromatherapy / Heal Bell, Iron Head
Corsola sucked, the typing and stats were horrendous for walling, but these stats inject life into it. The moves aren't special apart from the former move, but they suit the typing.

[SirBlaziken]

MegaEmpoleon
Technician
(You people can get stats)
Same reason as Technician Scizor, plus, Metal claw would be an option.

[Turner]

Mega Yanmega would be awesome.

I just had a thought though...do Mega evolutions mean Pokemon that receive them now benefit from Eviolite?

Mega Beedrill

Ability: Speed Boost
90/120/70/45/80/110

[SirBlaziken]

About the evolite, wait, that's a good question. I have no idea.
