Though some Pokemon may look cool, others just don't have the same feel to them. Here is a list of some of the worst-looking Pokemon.
Pineco is a Pokemon that is literally a pinecone with eyes. The idea is not that original and doesn't look great.
This humanoid Pokemon in opinion is creepy with its blonde hair and purple skin.
Klink is a gear-looking Pokemon. It is literally just two identical gears with eyes continuouly turning on each other.
Though its design is unique, compared to other Pokemon Luvdisc is not very creatively designed. With its heart-like shape, it looks like a heart with eyes.
In opinon, this Pokemon looks average and is not unique. It is also very generic in terms of appearance.
Like Greedent, Lumineon has a very generic and average look as it is just a black and pink fish.
While Bruxish has a good moveset and decent stats, its appearance is rather scary with its antennae and sharp teeth.
With Voltorb looking very closely like a Pokeball, I find it annoying that it does so, because it tricks trainers into battling them when all they wanted was to pick up the Pokeball.
Though it has an interesting moveset, Mannetric is another generic-looking Pokemon, as there are many other lightning-cat Pokemon.
Dedenne is just like a mixture of Pikachu and Raichu. It seems like it is the creator's attempt to create new Pokemon, even though it looks very unoriginal.
