Welcome to the RBY Ubers Viability Ranking Thread! If you're not familiar with the concept, we place Pokémon in ranks, based on how necessary they are on highly competitive teams. It will hopefully give you a good impression of the tier, to help with teambuilding. Pokémon are sorted alphabetically within each rank.
If you feel that a Pokémon is misplaced, feel free to make a post about it – that's what this thread is for.
Tier Format:

OP-
Mew – Physical sweeper, mixed wall, paralysis spreader, transformer and boomer – best fellow Mew check; scariest threat for standard ubers teams.
S Rank
These Pokemon excel at their roles in the RBY Ubers tier to such a point that you find numerous of them on serious teams.
