Pikachu clone Tier list (reasoning in comments)

Reasons for placements:

S tier:
Pikachu, Mimikyu

Of course I gotta put the absolute original On top. He's the Pioneer and the most popular pokemon ever!
Mimikyu Is very high up because it's the most unique and memorable pika clone, with typing (ghost fairy), Signature move (disguise) , and Lore. He's Very cool

A tier: Raichu (alolan), dedenne, Pachirisu

Alolan raichu is higher than its kantonian form because of the uniqueness. I find it neat that it's gimmick is that it looks like a surfer and different from normal pikachu unlike normal raichu that's basically just a pikachu with upgrades (even though that's what it literally is)
Dedenne is in a tier because of design and vibe. It looks like a small computer mouse or wifi router and I think it's cute. It's also an important lil guy in the xyz Pokemon anime so that helps it.
Pachirisu is in s tier because of how it's not really a mouse (or supposed to be),
It's a squirrel. Its Like it's own little thing while the others Are mouses. The first pika clone to try and stray away and also I think the designs cute

B tier: Plusle, Minum, Raichu (Kantonian), Pichu, Emolga

Plusle and Minum don't really get used but they are still very memorable and cool designed, like their Positive and negative. All though I understand these are pikachu clones, I feel like their design is too close to pikachu which kinda ruins the vibe for me honestly and ruins their Uniqueness. I still love them though. Raichu is a pretty fun dude, but personally, he looks like an alternate form pikachu and not really like an evolution to me tbh. That's why I like the Alolan form better. Pichu is in b tier because it's adorable and I love it but I hate it also. Moving on. Emolga is in b tier because the same reason as pichu. EMOLGA SWEPT MY WHOLE TEAM ON POKEMON SHOWDOWN AND EVER SINCE I DISLIKE it AF but it's so cute I can't stay mad at it

C tier: Togedemaru, Morpeko

Both Togedemaru and Morpeko are pretty forgetful in the vastness of pikachu clones, but if I had to pick which one was more rememberable, it's morpeko with its gimmick to change personalities if it's slightly rumbling and the first Pokemon to be electric dark type, but it gives it like 4 weaknesses. And Togedemaru, togedemaru is just forgetful. The only reason why I remember it is because I absolutely hate it as the totem Pokemon in ultra sun and moon. MY POOR PRIMARINA 😭😭😭

D tier: Pawmi, Maril.
Maril isn't even a pika clone, yet it's here. WHY??? so in utter confusion, maril is in d tier. Pawmi is in d tier even though it's unique. Why? Well, it is the first clone to evolve, and that should've made it higher, but there's a problem, every evolution looks the same, just different colour or size. It's very confusing. And I don't really like it's design much.
