So coming in at 54th is Swadloon from Unova. So Swadloon is down here because I just personally dont really enjoy Swadloon... Sewaddle I feel like is cute and has a lot of potential and then it invlolves into this bag of leaves. The good part though is that this bag of leaves can learn some decent moves of different types. Other than that Swadloon is just pretty much kind of ehh. Its not awful. I would consider Swadloon to be a minor inconvenince like hitting 2 red lights in a row. Also look at its facial expression. It looks like a high school teacher when you tell them you forgot to do your homework.
Ledyba is the next on the list. Now to be honest the johto region is the one I know the least about. Ledyba by the looks of it just isnt really an impressive pokemon in any way. Its attack is ehh and its defense its ehh and its not the most cute or intimidating thing. So Yeah Ledyba is just not a great time and is a pretty fluff pokemon from what I understand.
Pineco is just a funny looking pokemon. I mean who got high in the 2nd gen and was like "Lets make a freaking floating pine cone" and now here we are. Pineco is also bug type for who knows what reason. Like when I hear pine cone I guess I think grass but nope we got a bug. Other than that though in my experience pineco is a decent pokemon in battle and evolves into a pretty good pokemon also. I mean just the idea and design is what brings it down so far.
