3 clues!

No, it is neither Hydreigon nor Empoleon.

 

Not Delphox either.

1. It’s a fully evolved Pokémon.
2. It has a double weakness.

 

Not Aggron.

 

Tyranitar

 

No.
1. It’s a fully evolved Pokémon.
2. It has a double weakeness.
3. It’s a cottony/fluffy Pokémon. (Not the ability Fluffy, sorry for any confusion.)

 

Only Dubwool(Normal type) and Bewear(Normal/Fighting type) have fluffy. They don't suit your second rule.

 

Sorry for the confusion, I should’ve specified that the design has cotton or something else that’s fluffy, not the ability fluffy.

 

Imma say . . . Whimsicott.

 

Not Whimsicott

 

Uhh, what about Altaria then?

 

It’s also not Altaria. Should I reveal the answer?

 

Ok then. It was Jumpluff

 

So, who's going to be the next cluegiver?

 

I guess you can do it Sethal

 

Ok, sorry for the delay, didn't saw the message.

Hint 1: The Pokémon in Question is a Psychic Type. It may or may not have a second type.

 

Girafarig

 

grumpig.
