Summary
The augmented reality mobile video gamePokemon Gois one of the most popular mobile games around and has been since released back in 2016. It was developed and published by Niantic with help from Nintendo and The Pokemon Company. There are over 600 Pokemon to obtain at the moment, many of which require evolving.
To evolve certain Pokemon inPokemon GO, the trainer needs Candy. This is a consumable resource unique to the specific Pokemon’s family (that also strengthens the Pokemon). Candy is acquired through capturing, hatching, transferring, evolving, using Rare Candy, walking Buddy Pokemon, feeding Pokemon berries, and trading.Many Pokemon only need some Candy for evolution — but some need astronomical amounts.
Updated on July 10, 2025, by Ben Painter:Pokemon Go remains a favorite game among fans. Whether they are casual players who like to play while out on a walk or hardcore fans who dedicate time to collecting and leveling up all the available ‘mons, some Pokemon in those games require a few candies to evolve, the first stage of a three-stage evolution, for example. But others require an obscene amount, which requires a lot of time and effort to acquire. This update adds three more of the Pokemon, which are the most expensive to evolve inPokemon Go.
20Seadra To Kingdra
100 Candies
Seadra is a Water-type Pokemon that evolves into Kingdra (Water and Dragon-type) after eating a decent amount of Candy — 100, to be precise.Also, this greedy little seahorse requires a Dragon Scale too.
Its Quick moves are Dragon Breath (Dragon), Waterfall (Water), and Water Gun (Water). Kingdra’s Charge moves are Blizzard (Ice), Hydro Pump (Water), Outrage (Dragon), and Octazooka (Water).
At Level 50, it has a Max CP of 2,986, an Attack of 194, a Defense of 194, and a Stamina of 181. Kingdra does alright in the Great League, and even better in the Ultra League. There are better Water-type and Dragon-type Pokemon out there, but the dual typing does wonders. As for the Master League, do not even bother. It will perish disastrously.
19Magneton To Magnezone
Magneton is an Electric and Steel-type Pokemonthat evolves into Magnezoneafter consuming a lot of Candy — 100 actually.(Magneton itself evolves from Magnemite after eating 25 Candy a too, so it is more like 125 Candy!) On top of that, this entitled cluster of magnets requires the trainer to evolve it while in range of a PokeStop that has the Magnetic Lure Module attached.
Magnezone’s Quick moves are Charge Beam (Electric) and Spark (Electric). Its Charge moves are Flash Cannon (Steel), Mirror Shot (Steel), Wild Charge (Electric), and Zap Cannon (Electric).
At Level 50, Magnezone has a Max CP of 3,623, an Attack of 238, a Defense of 205, and a Stamina of 172. It actually does okay in the Great League and performs even better in the Master League. Magnezone, however, does less than okay in the Ultra League.
18Snorunt To Froslass
Snorunt is an Ice-type Pokemon that evolves into Froslass (Ice and Ghost-type) after swallowing a hundred (100) Candy.But if that Snorunt is male? Nope.It will become a Glalie(Ice-type). Female though? Froslass! However, there is one more thing it requires: a Sinnoh Stone.
Froslass’s Quick moves are Powder Snow (Ice) and Hex (Ghost). Its Charge moves are Shadow Ball (Ghost), Avalance (Ice), and Crunch (Dark).
At Level 50, Froslass has a Max CP of 2,306, an Attack of 238, a Defense of 205, and a Stamina of 172. When competing in the Great League, it battles nicely!
17Kirlia To Gallade
Kirlia is a Psychic-typePokemon that evolves into Gallade(Psychic and Fighting-type) after munching on a whopping 100 Candy.(Kirlia itself evolves from Ralts after consuming 25 Candy too, so it is really 125 Candy!) However, Kirlia needs to be male, because if it is female then it will evolve into Gardevoir. Also, Kirlia needs a Sinnoh Stone on top of everything else.
Gallade’s Quick moves are Low Kick (Fighting), Confusion (Psychic), and Charm (Fairy). Its Charge moves are Psychic (Psychic), Leaf Blade (Grass), Close Combat (Fighting), and Sycnhronoise (Psychic). When in Shadow mode, Gallade has Frustration (Normal), and Return (Normal) when Purified.
At Level 50, Gallade has a Max CP of 3,497, an Attack of 237, a Defense of 195, and a Stamina of 169. All around, it is not bad in competitions. Gallade performs mediocrely in the Master League, decently in the Ultra League, and better than average in the Great League.
16Feebas To Milotic
Feebas is a Water-type Pokemon that evolves into Milotic once it stomachs around a hundred Candy, give or take (not actually, 100 on the dot).That being said, this ugly little fish needs more than just sweets to become a big beautiful serpent. The trainer must walk an extraordinary distance with Feebas as their buddy — 20 kilometers!
Milotic’s Quick movesare Dragon Tail (Dragon), Waterfall (Water), and Water Gun (Water). Its Charge moves are Hyper Beam (Normal), Blizzard (Ice), and Surf (Water).
At Level 50, Milotic has a Max CP of 3,398, an Attack of 192, a Defense of 219, and a Stamina of 216. Unfortunately, it fights poorly in every competition (Great League, Ultra League, and Master League). Milotic will survive a bit in the Ultra League and Master League, but there are just better choices out there for Water-type Pokemon.
15Pumpkaboo To Gourgeist
200 Candies
This Halloween-inspired Pokemon was released in October of 2021, and it is a unique Pokemon as it comes in four different sizes: Small, Average, Large and Super. Something for gamers to collect, and each one as a shiny as well.Gourgeist cannot be caught on its own, and it must be located as a Pumpkaboo and then evolved. Which will take 200 Candies, or if gamers prefer, they could trade with a friend instead to evolve it that way.
When using a Gourgeist in battle, it has the Quick moves of Hex (Ghost) and Razor Leaf (Grass). It also has access to the Charged moves: Fire Blast (Fire), Foul Play (Dark), Poltergeist (Ghost), Seed Bomb (Grass) and Shadow Ball (Ghost).
It has a Max CP of 2,633, and when at level 50, there is nothing to write home about with a 171 Attack, 219 Defense, and 146 Stamina at maximum rating. Unfortunately, it does not perform well in the Ultra League or the Master League, and there are better choices for Pokemon of its type.
14Phantump To Trevenant
Another Pokemon which will take 200 Candies to evolve is Phantump to Trevenant, but this can be avoided if gamers have someone to trade with. Leaving all the Candies gained from catching Phantump to leveling up to get the best Trevenant possible. There is nothing extra needed for this tree, so this is a fairly straightforward evolution, albeit the amount of Candies.
There is not a lot of room for movementwhen it comes to its attacks. Its Quick moves are Shadow Claw (Ghost) and Sucker Punch (Dark). Its Charged attacks are Foul Play (Dark), Seed Bomb (Grass) and Shadow Ball, not too many variations here, but some powerful attacks for those Gym Battles, Team Rocket Grunts or PVP Battles.
The Ghost/Grass type haunted tree has a max CP of 2893 at level 50 and can reach heights of 201 Attack, 154 Defense and 198 Stamina. It can shine in the Great League but struggles in the Ultra League or Master League.
13Shelmet To Accelgor
Gamers will need 200 Candy to evolve Shelmet into Accelgor, however, there is a way around this through trade, requiring no candies at all.This may be difficult without a friend who also plays the game.
Accelgor is a Bug type and has Acid (Poison) and Infestation (Bug) as its Quick Moves. With Bug Buzz (Bug), Signal Beam (Bug), Focus Blast (Fighting) and Acid Spray (Poison) as its Charge Moves.
Its Max CP is 2,441 with 220 Attack, 120 Defense and 190 Stamina, sadly not a great Pokemon with a lot of weaknesses thanks to its Bug typing. If players cannot trade to evolve, then gathering 200 candies for this may not be worth it at all.
12Karrablast To Escavalier
Another Bug Pokemon and just like Shelmet, Karrablast requires 200 Candy to evolve into its second form Escavalier, but this can be completely skipped with a trade.Karrablast and Shelmet, in the mainline games only evolve in a trade with each other.
Escavalier gains the Steel secondary typing with this evolution and its Quick Moves are Bug Bite (Bug) and Counter (Fighting). Megahorn (Bug), Aerial Ace (Flying), Drill Run (Ground) and Acid Spray (Poison) make up its pool of Charged Attacks, offering a wide coverage of types.
It can reach a Max CP of 2,889 with 223 Attack, 187 Defense and 172 Stamina, a better Pokemon overall than its sibling Accelgor. If gamers need to choose between the two, then Escavalier is the way to go.
11Poipole To Naganadel
This Poison/Dragon-type Pokemon is an Ultra Beast and will evolve from Poipole when fed 200 Candies, but gamers must also catch 20 Dragon-type Pokemon while walking with it as a buddy.Something that may be difficult due to Dragons being fairly rare in the wild. Gamers were given a Poipole as part of the World of Wonders special research event, so at least it was easy to acquire.
When in battle, its Quick moves are Air Slash (Flying) and Poison Jab (Poison). These Charged attacks are Dragon Claw (Dragon), Sludge Bomb (Poison), Dragon Pulse (Dragon), Acrobatics (Flying) and Fell Stinger (Bug). A lot of ways players can go when using Naganadel against other trainers.
With a max CP of 3587, it can become an awesome Pokemon to use inPokemon Go, and it will not look out of place in the Great League or Ultra League. The Master League may be a step too far. At max level, it has 263 Attack, 159 Defense and 177 Stamina, which is not too shabby.
