*Grumbles that Chikorita is actually really good in the games if you use it properly*
Okay, so my top 5 worst starters, largely based on my favorites, but I'm also taking their usefulness (mainly in game, not so much competitively since most of them are outside tiers I know anything about) into account
5. Samurott
Okay, don't get me wrong, I love this guy. But he's just so damn bad. Literally the only positive he has is that he has a great movepool. But he just doesn't have the stats to back it up
4. Delphox
Okay, no, Delphox, you suck and I can't stand your design. Fennekin was awesome but then you stood up on your hind legs and became this weird wizard thing. It's nice and fitting considering the other two starters, but I still don't like it. And you're just useless in a fight most of the time, at least compared to the lightning fast Greninja and the unbreakable bastion of Chesnaut
3. Charizard
I have never liked Charizard at all. But then Charizard Y happened. Charizard Y was awesome and well designed whilst still remaining simplistic and not over-the-top. And then Charizard X happened and all that went out the window. However the main reason I dislike this Pokemon is because of the way people who like him act about him. He's like a T-rex, everyone acts like he's the biggest and most powerful even though he's not actually all that great
2. Pikachu
I started with Pokemon Yellow, so I'm actually really attached to this guy. I didn't even mind that he couldn't evolve, he was my partner and I didn't care what choices he made. Then I found out people P much act the same with him as Charizard and while I still love Pix, I am not a fan of his species as a whole any longer. Unlike a lot of the other things on this list, he's actually useful going through the game he's a starter in, so that's worth noting. He packs Thunder Wave as well as a slew of powerful offensive moves allowing him to sow status and dish out damage. The only downside is he's literally useless against Brock as nothing in his movepool at the time can even do anything to Ground/Rock types. Still, I can't get over the T-rex syndrome applied to him so overall he's really low on my list
1. Emboar
Okay, so, Fire/Fighting typing was bad enough. But then they turned Tepig (which is adorable) into this obese monstrosity that looks like a Snorlax had an affair with a Grumpig and the baby was left to grow up with a family of Torkoal (I am really not a fan of Emboar. though I actually like all of the aforementioned Pokemon) On top of that, it's generally pretty bad as well. It's got great offenses and HP, but then it's terribly slow and has fairly low defenses. IIRC it's movepool is okay but not the greatest
