What Pokémon do you think is the least hated? Do keep in mind that even Pokémon with overwhelming amount of positivity attached to them within the fandom also attract a fair amount of contrarians or special cases who have experienced the aforementioned Pokémon in a bad light as a result; That doesn't necessarily discredit any of these hypothetical Pokémon, but I thought i'd mention it.
