Since recently "pokémon" has changed to "pokemon", it has not been applied globally. So here's all the remaning tags (220) with é in order of count. Since a lot of these already have aliases in the wrong direction, it is not possible to create a BUR for most of these, I assume a moderator has to take care of that instead.

In addition, some of these have aliases containing "pokémon" but not "pokemon", such as leaf_(pokémon) having aliases leaf_(pokemon) and green_(pokémon) but not green_(pokemon).

Some of these should probably go away. Like pokémon_move, pokémon_rse (which is just the gen 3 games, Ruby, Sapphire, and Emerald), pokémon_gsc (the gen 2 games, Gold, Silver, and Crystal), and probably more.

baby_pokémon is aliased away already.

pokémon_tcg_(game) and pokémon_tcg seem to be the same thing.

Tags which have already been aliased and require recounts:

baby_pokémon
lass_(pokémon)
sailor_(pokémon)
daisy_(pokémon)
tuber_(pokémon)
regional_form_(pokémon)
legendary_pokémon
pokémon_go
pokémon_unite
milo_(pokémon)
raihan_(pokémon)
piers_(pokémon)
allister_(pokémon)
lenora_(pokémon)
chuck_(pokémon)
roark_(pokémon)
janine_(pokémon)
pokémon_trainer

Tags with 0 active posts:

pokémon-fan-2019 (artist whose 2 posts were deleted for crapness)
noodle_pokémon (this was somebody trying to be funny in the tags section, and wouldn't you know it, they have previous)

Tags which should be aliased:

monster_card_(pokémon) -> pokémon_card (100% post overlap)
pokémon_trainer_hat -> hat (there's no such thing, this could describe literally any hat and the pokémon_trainer tag is vague enough as it is)
hyper_potion_(pokémon) -> potion_(pokémon) (too similar, unlikely to be either tagged or depicted correctly, 100% post overlap at present, often confused with the unrelated hyper_potion tag which means something quite different. See also: max_potion, super_potion)

Pokémon species:

ditto_(pokémon)
hypno_(pokémon)

unown_(pokémon)

akua_(pokémon_gold_beta)

Pokémon species groups:

fossil_pokémon
beta_pokémon_(species)

Pokémon species forms (canon):

shadow_pokémon
alpha_pokémon
tera_pokémon

Pokémon game mechanics:

pokémon_move
pokémon_amie
pokémon_refresh
pokémon_camp
potion_(pokémon)
pokémon_egg
pokémon_cry
pokémon_center
pokémon_battle
lake_ball_(pokémon)

If anyone else was wondering, the Lake Ball appeared in one episode of the anime and nowhere else. One for the "hey, it's technically canon" pile along with the small mountain of grandfathered-in character-of-the-day waifu posts.

Pokémon games:

beta_pokémon_games
pokémon_gold_beta
pokémon_café_mix
pokémon_snap
pokémon:_let's_go
pokémon_colosseum
pokémon_art_academy
pokémon_masters
pokémon_stadium
learn_with_pokémon:_typing_adventure
pokémon_bank
pokémon_tcg_(game)
pokémon_rgby
pokémon_gsc
pokémon_rse

I would quite like those last three to be aliased away, similarly to pokémon_swsh.

pokémon_tcg_(game) describes the Game Boy title based on the TCG, as distinct from the TCG itself. That said it's not the best name and it only has two (related) posts, so would be no great loss.

Is there any justification for the beta_pokémon_games tag? Are we hoping that a leak of a different game will both happen in the future and contain enough unreleased content to justify a second subtag?

Other Pokémon canon:

pokémon_tcg
pokémon_detective_pikachu
pokémon_ranger

That last tag probably requires disambiguation. It refers to, and has been used for, three different meanings: the game series of that name, the group of characters who star in that series, or an unrelated group of NPCs who were introduced to the core series games a generation after the last Ranger game was released.

Whither pokéshaming?
(I saw topic #33688 but there didn't seem to be a consensus about aliasing it away or not, so perhaps it should be included here.)

edit: I just mean switching the alias(es) to point to pokeshaming instead.

It might sneak by as a meme, or at the very least I'd be in favor of a broader "pet_shaming" tag that includes non-Pokemon too.

it seems like most of the comments supported aliasing it all to petshaming

You are right that there are additional tags starting with "poké". I only listed those with "pokémon". So here are the remaning poké tags still having é:
