Bad: I must agree Drifblim could use the boost. Mainly because it's one of my favorite Ghost-types. Good: Torterra. Torterra counts, right? It's like the best Grass-type I've ever seen. Legend: Raikou. Giant badass lightning sabretooth tiger please.

Not really sure what constitutes "good" or "bad," as it seems a bit vague here. What I will say is that Flygon is in desperate need of a Mega. It needs something to separate itself from the mightier dragons, like a substantial speed boost. It did always look fast.
As for a legendary, Darkrai could be really cool with a Mega Evolution.

Not sure don't care if I think they are bad Pretty much all the pokemon that got the mega evos I was super psyched for and wanted; but uhh Zoroark and all the mainstream dragon pokemon evolution chains in each generation.
Then definitely Giratina and maybe Lugia. But as my theory all pokemon will get mega evos the only ones I could see not getting it is the Eevee's but now I think it would be weird to leave out eevee's so now I am thinking crap maybe it is only a select few that get mega evos.
