Genesect is a bipedal, cybernetic insectile Pokémon. It has a purple metallic body with a wide, flat head that is saucer-shaped. It has two red eyes and a wide mouth with exposed white teeth, giving it a grinning appearance. It carries a powerful laser-firing cannon on its back that was upgraded and added onto it by Team Plasma when they made the modifications to it. Various drives can be attached to Genesect's cannon to allow it to fire different elemental beams. Genesect's thorax is powerfully-built, and it has a heavily-armored metal exoskeleton. Its arms and legs are plated with segmented metal parts. There is a pale purple stripe across its diamond-shaped abdomen.
If the player takes a Genesect to the P2 Laboratory and shows it to the scientist there, he will battle the player. If the player wins, the scientist gives him/her two out of the four drives, with the two being different depending on the version of the game. The Genesect must be from the event or it will not work, if you got it by hacks then you will battle the scientist but you will not get the drives.
Genesect's move, Techno Blast, is somewhat similar to Arceus's Judgement, basing its typing on its held item.
Genesect is classified as the Paleozoic Pokémon because it existed during the Paleozoic Era, a time period more than 300 million years ago.
In the P2 Laboratory, there is a memo presumably written by Ghetsis stating that Lord N had modified what is to be the strongest Pokémon ever until he abandoned the project, likely because N is compassionate to the feelings of Pokémon.
CoroCoro leaked it and revealed on July 11, 2012.
Genesect is shown on a teaser after the pre-release of the fifteenth Pokémon movie.
Even though Genesect uses its signature move, Techno Blast, Genesect doesn't receive STAB from it.
Genesect is the only prehistoric Pokémon that is not a Rock-type.
It is also the only prehistoric Pokémon that can not be restored from a fossil.
It has been revealed by Nintendo that when you bought Pokémon Black and White Versions 2, you could have received Genesect through Nintendo WiFi from October 11 to November 12.
Genesect is one of the only two Bug Pokémon that can learn Fly, the other being Volcarona.
Interestingly, neither of these Pokémon are the Flying type.
Genesect is the second Pokémon to be created in a Laboratory, the first being Mewtwo.
However, while Mewtwo is a clone, Genesect is a genetically altered version of a Pokémon that existed thousands of years ago.
Genesect could mean Genetical Insect (since it is one of the first Pokémon World terrestrial) or "genetic" (genetic), with English word "insect" (insect in Castilian) due to its bug type. It is also possible that the name is combination of the words "genocide", due to its purpose as a war machine, and "insect", again due to its bug type.
