Unova Reboot Pokemon
Throh & Sawk
Throh and Sawk are Unova's versions of Hitmonlee and Hitmonchan. One is skilled in fighting one way, while the other fights another way. Hitmonlee is known as a kicking pokemon and Hitmonchan is known as the Punching Pokémon. Although the style of fighting is different. Throh is the Judo Pokémon, which implies it fights using judo. Sawk is the Karate Pokémon which implies it uses karate. Once again, different fighting styles for two non-related Pokémon, even though Tyrogue is the one relation of Hitmonchan and Hitmonlee.
Munna & Musharna
You guys remember Drowzee and Hypno right? Well, Munna and Musharna are essentially the same thing, except Munna evolves with a Moonstone. However, both Drowzee and Hypno, and Munna and Musharna are Psychic type Pokémon that eat dreams. Drowzee also kind of looks like a tapir because it's based off of the Baku, just like Munna & Musharna. I mean at least Sawk and Throh were based off of different styles than Hitmonlee & Hitmonchan. These guys are based off of the same thing.
Klink, Klang, Klinklang
These Pokémon may be pure steel, but they can use electric type moves. They are actually based off of gears and how a group of gears work together, but isn't there another steel type pokemon that has magnets working together? That's right Magnemite, Magneton, and Magnezone. Even though most of the reboots are based off of Kanto Pokémon, they felt the need to give a Magnezone reboot, which I find awesome. They also evolve at different levels, which is fair considering you don't want two Pokémon to seem too similar.
Timburr, Gurdurr, & Conkeldurr
This evolutionary line is a reboot of the Machop, Machoke, Machamp line. Even the last evolution requires a trade for it. Timburr, holds a piece of timber, hence its name, and is known to help out construction workers. The entire evolutionary line has unusually massive veins and objects normally found at construction sites in their names. These Pokémon are based off of construction, while the Machamp line is based off of strength in fighting. Both activities involve muscular men in one way or another.
Woobat & Swoobat
Although the typing is different. Woobat and Swoobat are definitely based off of Zubat and Golbat. Their names even rhyme with Zubat. Zubat and Golbat are Poison and Flying types, but Woobat and Swoobat are Psychic and Flying. Also, Woobat evolves into Swoobat by friendship or happiness with the trainer, like how you get Crobat. The typing change does help a lot with gyms though. If you look at Woobat and Zubat, you'll notice both don't have eyes, because they use echolocation like regular bats do. When they evolve, they grow eyes, somehow, but still can use the echolocation.
Tympole, Palpitoad, & Seismitoad
These three are a reboot of Poliwag, Poliwhirl, and Poliwrath. These three have better typing though. Being part Ground type after evolving once means electric type moves can't touch them, but leaving them X4 damage against Grass. They are evolved by leveling up, while Poliwhirl needs a Water Stone to become a Poliwrath. Essentially, the toad concept seems to be the only real reboot from it.
Roggenrola, Boldore, & Gigalath
I actually like the reboot more than the original concept with these guys. Geodude, Graveler, & Golem are cool and all, but they are X4 times weak to Grass. These guys are only X2 weak since it only has one type. Both the final evolutions evolve by trade and both also evolve at level 25. I'd still rather have a Gigalath than a Golem though.
Trubbish & Garbodor
Even though a lot of people talk trash about Trubbish, no one remembers that it's one of the reboot pokemon of Grimer. Both Grimer & Muk and Trubbish & Garbador are pure poison and based off of a form of pollution. They also both evolve into a pile of bigger pollution. Both Pokémon evolve in the thirties, although a lot of Pokémon already evolve in the thirties.
Bouffalant is a Normal type bull with a perm. Tauros is a Normal type bull with a mane. Each is introduced late in the Pokedex. I really have nothing else to point out, the whole bull thing seems like proof enough to me, but feel free to have your own opinions.
Foongus & Amoonguss
Although, these are Grass and Poison types, and most Grass and Poison types don't seem to resemble them, except Vileplume but that's not who they are reboots of. They are reboots of Voltorb and Electrode, believe it or not. They are both fake Pokeballs that will attack you in the game they are introduced in. Voltorb and Electrode's full body looks like a pokeball, but Foongus and Amoonguss only have their mushroom heads that resemble Pokémon.
Audino is more of my opinion as a reboot, rather than something obvious. I believe it's a reboot of Chansey because it just gives off that vibe. It also gives you a lot of experience points when you beat it. As I said earlier, this one isn't something obvious and is my opinion a reboot. If I'm wrong, then so be it.
Dwebble & Crustle
Come on, guys, we've had a hermit crab hold things on it's back before. You know the ones, those lovely Bug and Grass types Paras and Parasect. Although Dwebble & Crustle are Rock types instead of Grass, they seem like the same concept of hermit crabs. I'm happy for their typing though. If we let it be a Water and Rock type like a crab normally is, we'd have a lot of Rock and Water types. Corsola, Relicanth, Omanyte, Omastar, the list goes on.
Zorua & Zoroark
This one I've heard more from other people than my thoughts. Zorua & Zoroark are reboots of Riolu & Lucario. I don't see the reason why they are reboots personally, but I guess they both do give off that vibe. Both had their own movies, even though they aren't legendaries and both are only obtainable once in the game they are introduced in.
Drilbur & Excadrill
Better version of Diglett and Dugtrio in my opinion. And yes, they do seem like reboots of Diglett and Dugtrio. Both of them are Ground type Mole Pokémon. Although, Excadrill evolves into a Steel Type, they still have resemblance. Although, they could also be reboots of Rhyhorn and Rhydon, but that seems less likely.
These are all the reboots that I've come across from playing Pokémon Black, Pokémon White, Pokémon Black 2, and Pokémon White 2. If I missed any reboots, I do apologize and know that even though it seems like I don't like these guys because they're reboots, I actually love each one as a hardcore Pokémon fan. I did not include the common Normal type reboots, as well as the Flying Bug and Poison Bug reboots. As well as the Bird Reboot in each generation. Also, Emolga is obviously the Pikachu reboot, so I did not include it on the list. If you think any other Unova Region Pokémon are reboots of previously existed Pokémon, you can comment them below and don't be Krabby about it.
