Lapras: An evolution wouldn't work. A pre-evolution would be much better, though.
Dewgong: Maybe, But I couldn't see it happening. If anything, maybe a baby Pokemon would be cute. ^.^
Delibird: This Pokemon is pretty much a loner and one of the most under rated Pokemon [besides Dunsparce]. It NEEDS an evolution to spiff it up.
Jynx: I, personally, would find it interesting to see a Jynx evo, but I really can't see it happening. I think she's going to be stuck in the category 'has a baby Pokemon, but doesn't evolve' with Mr. Mime and Sudowoodo.
Abomnasnow: No. I think that's a rediculous idea. xD
I'd pick Delibird overall, though. ^.^
