Hello guise. I had this conversation with a couple of friends the other day and thought I would bring it here to get some more opinions. The topic? Disappointing Pokemon. One of mine is Machamp in Pokemon Black 2. I got mine from Reuniclus as an egg, trained him up to level 65 and his stats seem fine but he faints way to quick. I love Machamp as a Pokemon but not as a party member. So disappointing...

Got a Pokemon that you wish was cooler, stronger, faster, better? Feel free to add to this if you feel they are lacking or more could have been done with them.

Linoone is a little disappointing in-game, but it's more useful for having along on a Hoenn team rather than keeping in a competitive team.

Arcanine and half the Eeveelutions (especially Flareon) are also pretty difficult to use on competitive teams.

Rhyperior. It has so much potential but it is let down by it's speed.
Smeargle. I just wish that it's attack was better and with such a wide movepool it's let down by that.

Umbreon. I love it and have one, but its only for Wish support.

Duskull/Dusclops..
It takes hits like a champ....but unless you have some heart scales it really isn't useful
cause of it's poor attacking stat and attacking movepool in game, although it is somewhat useful competitively

Sadly, Floatzel is not without his flaws. He's like a glass bullet. Extremely fast, even moreso in the rain, hits hard...but can be broken easily by an Electric or Grass-type move. A bit of a boost in defense would be ideal for the Sea Weasel.

Another one for me is Delibird. Overall this pokemon has a really cool concept especially considering the Black2/White2 pokedex entry.
-It carries food all day long. When someone is lost in the mountains, it shares that food.-
But it only has one move, Present. I wish they would have taken the Stockpile approach and gave him a few more moves revolved around his Present move.

Farfetch'd is pretty disappointing to me. 5 generations have passed and there's still no evolution for this guy. Despite getting Stick as a specific hold item for this Pokémon, it still doesn't fare well in battles because it has poor speed.

This might be a bit obvious to list, but Regigigas. For a legendary with incredible stats, they are almost useless for the ability it is cursed with, Slow Start. While not as bad, Archeops is also a bit of a let down because of it's terrible ability Defeatist. I never understood why potentially great pokemon are hampered by the ability they are given.

I would say Turtwig, but it's unevolved and that makes it quite obvious. So instead I'll say Torterra, since I use that sometimes as well. Its speed just kills me... when I first evolved Turtwig to it I just... stopped using it... but it has some pretty nice defense. But then it also lacks a lot in special defense, but he has HEAVY Sp. Def weaknesses. Ice, Fire, Water (Especially with Scald.)

Another one is Darmanitan's Zen Mode. How will I effectively plan such a flip-flop and use it in battle?

Well, let's see...

I really wish Sunflora was better. The fact that it literally gains no Speed upon evolution and that it's frail doesn't make it very good. Sunkern is just bad outside of the Pokéathlon, so I personally don't like it very much. Come to think, outside of Celebi, a lot of the Gen II Grass Types are really underwhelming. Jumpluff's a good support Pokémon, albeit kind of gimmicky, and Bellossom is forgettable. Meganium's okay, I guess.

Shedinja. Such a great concept, but it not only has six weaknesses, but weather kills it, burn or poison kill it, . Who doesn't have a Fire, Rock, Ice, Ghost, Dark, Flying, status-inducing, or weather move on at least two of their pokémon? Not only that, but its stats aren't too good to begin with. Interestingly enough, since it evolves from Nincada, its Attack is higher than its Special Attack, meaning that a pokémon with a Pokédex entry stating it never moves still hits harder with X-Scissor than with Shadow Ball?
Mew. Sure, she can do anything, but not that well. Give her whatever moveset you want, I can probably find another pokémon with a nearly identical moveset that has better stats where it counts for that particular strategy.
Gothitelle. I was looking forward to it once I found out about it, but it isn't good. At anything. Just check Serebii. It's just...bad.
Genesect. I really liked its concept, being similar to Mewtwo, but it seems like a weaker version of Arceus to me with regard to its type-changing stuff. Plus, a 4x weakness to Fire hurts a lot in competitive play.
Flygon. I finally got one to level 100 after some exhausting training, but it just...wasn't good. Maybe it has something to do with the fact that I didn't know of EVs at the time, but it disappointed me.
Blaziken. My chosen starter in Emerald, and I loved him. Then, I made it to the Elite Four. Wallace, the Water-type champion. His Wailord was able to 1HKO my highest leveled pokémon, my handsome Blaziken, every time. I spent a month training a Magnemite I went out and caught until it was level 92 before I was able to bring him down. I felt that my starter had failed me.

Luxray... dear god. Nintendo why must you make a Pokémon that looks so awesome with those stats and horrible movepool? Almost all of his moves are Electric, Dark, and Normal. Most lacking any real power. And most of his powerful ones are Special attacks, yet he's a physicial attacker. Notmally I would have overlooked this due to it's pre-evolution being a beginning game Pokémon but THEN I got a shiny Shinx. Still, it's really bad compared to other beginning game Pokémon such as Stoutland or the Pigeys.

The only shiny I ever found myself (aside from Soulsilver's Red Gyarados) was a pink Marill in Emerald. However, I was very new to pokémon at the time, and killed it to help train my Magnemite. I really regret that now, especially since it's going to be a Fairy-type next gen.
Also, all of my starters have been male. Every single one. I really wanted a female Snivy for...no real reason. I just did.
Why can't you play as a girl in Colosseum or XD? They were my first pokémon games.
Lopunny. Not sure why, but I liked her as a pokémon. She's not good. In any way.
Spiritomb. I find its movepool really lacking. I always thought it was so cool, the pokémon with no weakness hidden in a crumbling tower...
Blissey. Thanks to the Eviolite, Chansey is better.
Dusknoir. I always loved his evolutionary line, but I never got mine to work. I don't know why.
Dunsparce. So wacky, so different...and so weak.

Baby Pokémon such as Munchlax, Pichu, Azurill, igglybluff.... just why? They can't breed. Some can't even be hatched unless a parent is holding a certain item. Almost all have horrible stats. I can't even see a reason of why they were added. To be cute? Hardly. Igglybluff looks like it's going to crawl down your throat and devour your soul.

Oh, I almost forgot, Budew. I spend more time training Budew to evolve into Roselia than any other part of Pokémon Diamond. It's annoying and stupid. And by the time it evolves into Roselia, it's missed the chance to learn some good moves. D:

Flygon for reasons already mentioned
Gyarados got weaker
And on the flipside, I wasn't expecting the amounts of pure ownage Ho-OH and Lugia have in HG/SS.

Uhm, Mightyena. I really, really love its design (I like it better than Houdoom) but it's stats are so meager. It's a derp. Though I do like that it got Moxie now.

Girafarig - Love the name. Palindrome! I also like its design. Stats, not so much. And honestly, I think it deserves an evo. It doesn't learn Hyper Beam.

Arbok/Seviper - :/ When will we get a snake Pokemon that'll be used in higher tiers? Not counting Contrary Serperior.

Solrock/Lunatone - I like the idea! Their stats pass for where they are, but it leaves a desire for something more. Personally, I like their dual type, despite it being a really bad dual type.

This is what I can think of that hasn't been mentioned. Others mentioned are Flygon and Machamp.

I'd say Tarous (sorry if I misspelled that) but he is acctualy usable. I'll say Buffolant. Its like a Tarous but not as good as it. I wish it was better. I also agree with Flygon, it could be better. Again, sorry if I misspelled anything.

I just recalled, Glalie. It's the jack of all trades with base 80 stats across the board, but master of none, as it's basically outclassed in almost every aspect. It's beaten out physically by things like Beartic and Weavile, defensively by Walrein and Rotom, and in speed by its counterpart, Froslass, along with Cryogonal.
