I kind of dislike Walrein—I find it to be a bit intimidating. It's got two gargantuan fangs, which are freakishly yellow. D: Its nose is pretty big, too. Also, the way that it's got all the hair wrapped around its head looks quite messy. If its fangs and nose were a bit smaller, and if its hair was a little… stylish, maybe, then it definitely would have looked better, in my opinion. In terms of competitive battling, Walrein is not very good either. It has an extremely low Speed, and its offensive and defensive stats are very, very poor. This Pokémon's got many weaknesses, including fire, electric, and electric, which are all very common in the metagame. If your team is not focused around hailstorm, then you'll be having a tough time utilizing this Pokémon. Last time I've ever used Walrein was about four years ago. Never touched it after that. And every time I went up against a Walrein, I was able to have it taken down in an instant—didn't need to break even a single sweat!
I'm also not a big fan of Sableye. It's a great Pokémon to use in battle, but when it comes to design, though, I just don't like it. Every time I look at it, it reminds me about one of those monsters that I used to imagine as a kid. ):
