>>22136333All the starters will eventually.
Gen 1, I would love megas for Machamp, Golem, Raichu and Dragonite.
Add another 2 in gen 2. Granbull and Crobat are my top picks for it. Ursaring, Octillary and Kingdra would be awesome as well.
Gen 3 has plenty, but I'm a flygonfag so obligatory.
Gen 4 could use a handful more. Weavile,Toxicroak and Drapion would be great.
Gen five obviously needs a lot. Darmanitan, Gigalith, Eelektross, Beartic, Druddigon, Golurk, Hydeigon and Volcarona would all make me happy.
Six needs a few, but the low number of options limits it a bit. The fossil pokemon would make great megas. Hawlucha and Noivern are my bros, so that would be nice. Maybe Pangoro, Heliolisk and Pyroar.
