Pyukumuku maybe. All it has are ridiculous defenses, literally no speed and HP, and an average atack stat that it can't even use properly.
Route 1 shitmons will probably become a burden as the game progresses as well (Persian, Raticate and my boy Gumshoos).
From the looks of it you also get Vikavolt and Crabominable very late in the game. They're alright but their speed is atrocious, which is unfortunate because that late into the game you're facing off against strong trainers and legendaries.
