Pokemon you never used?

[orangeralts21]

I have recently begun playing Pokemon XD again and have realized that I never use some Pokemon that are I have never used. Be it you personally don't like the Pokemon or it is plain bad (or maybe even you get it too late), What Pokemon did you never use in Colosseum and XD?

Personally, I have never used Ledian and Ledbya because they don't fit into my play style.
Also, I didn't use any Pokemon from late game like Tropius or Lickitung because I already had my party.

I haven't used the majority of XD/Colosseum Pokemon, I always only used the ones that would be in my 6 members party.

Hardly any on Colosseum, and I've never played XD.
