Life must be pretty bizarre for a Pokemon. One day, you’re a little fish swimming around the ocean, and the very next, you mysteriously turn into an octopus. It’s not exactly equitable to what we humans go through, having to wait millions of years for any meaningful change and all that.
Pokemon really put us to shame in that regard. Spend a few days outside, and your little monkey will have grown some boxing gloves or an extra pair of arms. Even more interesting with Pokemon is when their evolutionary path forks, letting them adapt to the surroundings of their world, and some of them sure do have a lot of diverging paths.
8 Rockruff – One Evolution, Three Forms
Rockruff is an adorable little puppy Pokemon introduced in Sun and Moon. You should treat them a bit like a dingo, though, because they’ve got quite the temper with that neck of sharp rocks. This little Rock–type is quite interesting, though, because even though they only have one evolution, it can take on three different forms.
The three forms of Rockruff’s evolved form, Lycanroc, are as follows:
Midday Lycanroc –
This form can be achieved by evolving Rockruff during the day while at level 25 or above.
Midnight Lycanroc –
This form can be achieved by evolving Rockruff during the night while at level 25 or above.
This form was introduced with Ultra Sun and Moon and can only be achieved by evolving a Rockruff with the Own Tempo ability during the evening.
These forms are also non-interchangeable, meaning once Rockruff evolves into Lycanroc, they are locked into their specific form.
7 Burmy – Two Evolutions, Three Forms
Burmy was introduced back in Diamond and Pearl, and they’re a somewhat indiscernible creature. According to the Pokedex, they are a bagworm, a subset of moths that create small bodies of various materials around them. In Burmy’s case, that is a coat of leaves, sand, or trash. True adaptation.
Mothim, as you can see from the listings, does not take the cloaks into consideration. Instead, they evolve into a Flying/Bug–type at level 20 if Burmy is male.
Wormadam (Plant Cloak) –
Wormadam goes in the opposite direction of Mothim, evolving at level 20 when Burmy is female, but also takes the cloak into account. For Plant Cloak Wormadam, this makes them a Grass/Bug–type.
Wormadam (Sandy Cloak) –
This form is achieved by evolving a female Burmy with the Sandy Cloak at level 20, and causes Wormadam to become a Ground/Bug–type.
Wormadam (Trash Cloak) –
This form is achieved by evolving a female Burmy with the Trash Cloak at level 20, and causes Wormadam to become a Steel/Bug–type.
Each Wormadam form is non-interchangeable, but each also comes with its own unique moves it learns as it levels up.
6 Poliwag – Three Evolutions
Poliwag is a confusing little tadpole that’s been around since the very beginning of Pokemon. Following the growth of an actual frog, it grows hands and legs once it evolves into Poliwhirl at level 25. At this point, they plateau in terms of evolution. They no longer evolve by levels but through specific items.
At any point after evolving into Poliwhirl, they can further evolve into Poliwrath after being exposed to a Water Stone. They also gain the Fighting–type, like real frogs do.
Politoed was only introduced in Gen 2, meaning they weren’t accessible in Poliwhirl’s original appearance. Like many early Pokemon, they can only be evolved while traded and holding a King’s Rock. You have to rely on the benevolence of others for this one.
Politoed is a distinct design shift from the original evolution family, but that’s okay.
5 Cosmog – Three Evolutions
Introduced in Sun and Moon, Cosmog is the first Legendary Pokemon that can evolve, though, in its defence, this is also a major point of the story. Cosmog is, technically, not a Pokemon at all but an Ultra Beast that got dragged into our world. They just also happen to evolve into the mascot Pokemon.
This is Cosmog’s first evolution, achieved at level 43, and only able to use Splash and Teleport.
Unlike other Pokemon, Solgaleo can still only be achieved in Pokemon Sun, Ultra Sun, and Sword. However, the Cosmeom can have come from any game, with its final form determined by the game it evolves in rather than the game it came from. It evolves at level 53
Unlike other Pokemon, Lunala can still only be achieved in Pokemon Moon, Ultra Moon, and Shield. However, the Cosmeom can have come from any game, with its final form determined by the game it evolves in rather than the game it came from. It evolves at level 53
Being able to obtain a second Cosmog means it is technically feasible to obtain both mascot Pokemon in a single version with a small amount of help.
4 Ralts – Three Evolutions
Ralts is a psychic Pokemon introduced in Ruby and Sapphire and is a member of one of the most well-known evolutionary lines in the franchise. With their original introduction, Ralts only had two evolutions, with a third introduced in Diamond and Pearl.
This is the first evolution of Ralts, achieved at level 20.
– This was the original final evolution of Ralts, achieved at level 30.
They were introduced in Gen 4, and only a male Kirlia can evolve into them when exposed to a Dawn Stone. However, there is no level restriction.
Unlike the rest of the main evolutions, Gallade also has a type change to psychic-fighting.
3 Tyrogue – Three Evolutions
Tyrogue is a fascinating exception in the Pokemon games because no other Pokemon has evolved like them or had previous Pokemon altered as much. Tyrogue has three different evolutions, though two of them existed as independent Pokemon in Gen 1.
– Introduced in Gen 1, Tyrogue evolves into Hitmonlee at level 20 if its attack is higher than its defence.
– Introduced in Gen 1, Tyrogue evolves into Hitmonchan at level 20 if its defence is higher than its attack.
– Introduced in Gen 2 alongside Tyrogue, they evolve into Hitmontop at level 20 if its attack and defence are equal.
Because of the nature of how Tyrogue evolves, it can actually require EV training so good luck getting those stats to line up correctly.
2 Wurmple – Four Evolutions
Did you know Pokemon began from a love of bug-catching? That’s why there are so many bug Pokemon out there, and Wurmple is one of the best. Not only are they very cute, but they also have four different evolutions.
– Wurmple evolves into Cascoon at level seven, decided by the random personality value assigned to it when it spawns.
– Wurmple evolves into Silcoon at level seven, decided by the random personality value assigned to it when it spawns.
– Cascoon evolves into Dustox at level ten.
– Silcoon evolves into Beautifly at level ten.
The only way to change Wurmple’s evolution is to catch another, as its personality value is determined at spawn, not during the evolution stage.
1 Eevee – Eight Eeveelutions
Though Pikachu was originally seen as the mascot of the series, Eevee has quickly jumped in popularity, even gaining its own featured game in Let’s Go. Eevee is iconic for its evolutions, lovingly dubbed Eeveelutions.
Eevee evolves into Vaporeon when exposed to a Water Stone.
Eevee evolves into Jolteon when exposed to a Thunder Stone.
Eevee evolves into Flareon when exposed to a Fire Stone.
Eevee evolves into Espeon when levelled up with high friendship during the day.
Eevee evolves into Umbreon when levelled up with high friendship during the night.
Eevee evolves into Leafeon when exposed to a Leaf Stone (or levelled up at Moss Rock in D&P)
Eevee evolves into Glaceon when exposed to a Ice Stone (or levelled up at IceRock in D&P)
Eevee evolves into Sylveon when levelled up with high friendship and a fairy move.
The greatest joy with Eevee is having so many evolutions to choose from.
