It's easy to overlook a game character in a game that has over 400 characters. even in Pokemon's early days when there were only 150, it still happened, and was understandable. Some of those we shrugged at were actually quite useful, however. Here are the top 10 underrated Pokemon.
Zubats are truly pests when you are trying to get to the other side of a cave. The appear constantly and waste your precious time. If you catch one, you find that it is quite weak and has a limited move set. If you train it, it will evolve into a goofy looking Golbat, and when you run into those in caves they're even more annoying! Stick with it, however, and you are rewarded with Crobat - a very fast Pokemon with high attack and lots of poison inducing moves at its disposal.
Rattata can be captured at the very beginning of the original games, and is quickly tossed to the side by many. It is normally caught around level 2, and even after gaining a few levels is pretty weak. Traienrs who decide to train Rattata anyway will eventually be rewarded with Raticate, who is even less cool because it's so fugly. The good news is that is can learn Hyper Fang, one of the more powerful normal type moves. Even cooler is that until generation 4, these were the only two Pokemon who could learn that move. Still not cool enough? The Japanese name of the attack is Certain-Kill Fang. Is that cool enough for you?
When Smeargle is first captured or hatched, it knows only a single attack - Sketch. Sketch is like Mimic, except the attack learned is permanent. As you level up, it will learn Sketch several more times, allowing you to customize Smeargle's move set using absolutely any move in the game! This takes a lot of work however, and you may need to battle a friend asked to specifically help you get the attacks you want. It's still a beastly Pokemon when you pick the right combination.
Like Rattata, Pidgeys can be caught at the very beginning of the original games. you probably discarded it into your PC as soon as you caught something cooler, but if you decide to stick with this guy, you are rewarded with Pidgeot - one of the best and coolest flying types in the game next to the legendary birds.
Wobbuffet was introduced in the second generation, and could be found in one of the last caves you enter in Johto. Honestly, he looks goofy as heck, and seems relatively useless. He can be extremely powerful if you know what you're doing, however. It can only learn a handful of moves. Using Mirror Coat and Counter, you can do devastating damage if you can read your opponent. Using Destiny Bond first ensures that even if Wobbuffet goes down, it still gets the last laugh.
When Nincada evolves into Ninjask, you will also get a Shedinja provided you have an extra Pokeball in your backpack, and an empty party slot. Shedinja is unique in that it is the only Pokemon with a ghost/bug type combination. It has a limited move pool, and only has 1 single hit point. What makes it worth having, then? The fact that it is completely impervious to all attacks that are not super effective or indirect(struggle, spikes, etc).
everyone knows that Magikarp is useless, and that it evolves into Gyarados, who is actually very, very popular. Why is he underrated then? Because every time you get the chance, you catch a Gyarados and the your Magikarp either sits in your PC or is released. But if you already have it's higher form, which is incredibly awesome, why keep the little weakling Magikarp? Well, Gyarados caught in the wild are a high level, while Magikarp are generally 5 and under (although it is possible to catch a level 100 Magikarp). A Pokemont rained from a lower level is stronger than one trained from a higher level, because it gathers "EV points" depending on the Pokemon it found while leveling up. The few of you that actually stuck with your Magikarp and raised it into the fearsome Gyarados it is were rewarded with an insanely powerful Gyarados. Those caught in the wild cannot rival it.
Rhydon isn't so much underrated as it is under used. I see it in very few parties, but it is insanely useful. If you come up against a water type, it can learn thunder! It can also learn surf, which does it very little good in battle compared to others, but if you are not a water type fan, or already have a water type in your party you don't with to teach surf to, Rhydon is the perfect solution. n the newer games, his ability, lightning rod, makes him a perfect pairing with any flying or water type.
Shuckle is a goofy looking turtle Pokemon which mostly defensive attacks. It's attack stats are also very low, and it barely does any damage. Thanks to this, many push Shuckle to the side. These people are missing the point. Shuckle is a wall. He has massive hit points and defense, and can wishstand almost any attack. If you want an annoying Pokemon to drive your opponent nuts trying to take it out, Shuckle is definitely a good choice.
Octillery is another very underrated and underused Pokemon. With a move pool of 53 different moves of 15 different types, the trainer is the potter, and the Octillery is his clay. Octillery has one of the lowest speeds of any Pokemon, but Trick room can easily fix that. In the hands of a skilled trainer, Octillery is a tank(pun somewhat unintended).
So, the next time you are playing Pokemon and you come across that weak looking Pokemon in the first routes of the game, or that pestering cave Pokemon, give it a chance. You may be surprised.
