When looking at a Pokedex, there are hundreds of ways one can categorize Pokemon. They have types, home regions, sizes, abilities, and so much more.

However, what can really make a Pokemon interesting is often hidden in their short Pokedex descriptions. Through these descriptions, many fans have found out interesting facts about Pokemon they otherwise wouldn't have known (unless they watch the movies or anime). One such fact is that not all Pokemon are natural creatures. In fact, many are artificial or even accidentally human-made.

10 Type: Null And Silvally

Introduced in the Sun & Moon games, Type: Null presented itself as a very unusual Pokemon design with what appears to be different parts of a creature all combined into one like a chimera.

Well, it looks that way because it was created in a lab by the Aether Foundation. They used cells from Pokemon of various types to create it, and planned to use it to fight Ultra Beasts. The helmet on its face is also human-made and meant to limit it from going berserk. Its evolved form, Silvally, is very similar, but it is brighter and has broken out of his helmet.

9 Castform

Castform originated from the Ruby & Sapphire games. Unlike Type: Null and its evolved form, Castform was created by friendly scientists at the Hoenn Weather Institute as a way to predict the weather. That is where Castforms various weather forms come in.

The Pokemon has a total of four forms that change depending on the weather. It has a normal form, Sunny Form, Rainy Form, and Snowy Form. What form it changes to also changes its type.

8 Golett And Golurk

Golurk from Pokemon Black and White.

These part Ground/Ghost-types first appeared in Black & White. Based on their Pokedex entries, fans know that these Golett and Golurk were created by an ancient civilization to protect Pokemon and people.

In fact, these Pokemon were originally made from clay (which explains why they are part Ground-type). As for their Ghost-part, scientists have not yet discovered what type of energy the Pokemon has within to have become sentient.

7 Porygon And Its Evolutions

Porygon in Pokemon Go.

Porygon was one of the first artificial Pokemon to be introduced to fans. It was created in the Cinnabar Lab in Kanto and was known to be a virtual-reality Pokemon due to being made through computer data and able to be in cyberspace as well as physically present.

Its evolutions are not caused by leveling, but through upgrades like one would use for a computer. When traded while holding an Upgrade, it'll evolve into Porygon-2; then, when Porygon-2 is traded while holding a Dubious Disc, it evolves into the glitch-inspired corrupted Porygon-Z.

6 Magearna

Part Steel-type and part Fairy-type, Magearna is a Pokemon created by a human 500 years ago. In its chest is a sphere known as its Soul-Heart, which was made from the life energy of other Pokemon.

The purpose of its creation was actually to be a present for a princess. Of course, that explains its adorable design. It also has the useful ability to feel the pain of others, and thus tries its best to keep others happy and healthy.

5 Mewtwo

Mewtwo is often the first Pokemon fans think of when considering a lab-made Pokemon. This is because Mewtwo being an artificial Pokemon was the main plot for the first Pokemon movie. It was created from an embryo of the Mythical Pokemon, Mew. Scientists performed gene-splicing experiments on the embryo to make it as powerful as possible.

Due to the cruelty and unethical nature of the Mewtwo experiments, Mewtwo is a very hostile Pokemon and does not easily trust humans.

4 Voltorb And Electrode

Voltorb and Electrode look like Poke Balls for a reason. According to their Pokedex entries, they first appeared at a company that developed Poke Balls. Based on rumor, it is believed these Electric-type Pokemon were actually once Poke Balls that gained sentience due to a powerful pulse of energy.

They do appear to run on electricity, and many other Pokedex entries note that Voltorb and Electrode typically can be found at power plants.

3 Baltoy And Claydol

The stories of Baltoy and Claydol are incredibly similiar to those of Golett and Golurk. Like those Ground- and Ghost-types, Baltoy and Claydol were crafted from clay by some ancient civilization. Unlike Golett and Golurk though, they are part Psychic-type, not Ghost.

It is rumored that Baltoy and Claydol were brought to life through some kind of mystical rays. Perhaps whatever animated them is the same substance that created Golett and Golurk?

2 Banette

This Ghost-types' backstory is a favorite of fans who like the creepier Pokemon. Banette is artificial because it actually was once a doll, the sort meant for children. What made it a Ghost Pokemon is that is was simply discarded for a long time.

The Pokedex entries also state that the doll has been driven to life through hate and grudge. This means the doll really did not like being cast aside.

1 Genesect

Game Pokemon GO Genesect Event

Team Plasma reconstructed Genesect from a fossil to try to make the most powerful Pokemon. The scientist that worked on it gave it a metallic body and canons.

N tried to cancel the project, but it was done behind his back. Some believe that Genesect is based on Kabutops, given its appearance and the fact that it was somehow created from or inspired by an ancient Pokemon.
