Name pokemon's whom are not popular, not seen much in the anime, not captured nor use much in games, and never have charm, cuteness to be popular...
for me, I think,
Dunsparce- never seen much of it in the anime and movies... and in games its weak and it has no evolution.
Spinda- id only seen it once during sinnoh, in games it might have a cool hypnosis attact but this pokemon looks lame to me...
Relicant- i dunno if this one is legendary or extinct. Just seen it once and cant find it in games..
Manectric- It looked awesome, but i dunno why it didnt shine in any matter! aswell as its pre evolution :(
Pinsir- never seen much of it in anime, in games so-so :(
Tropius- i dunno why, but i think it has only a few fanbase.
Lumineon- this one too.
