Genesect(ゲノセクト Genosect) is a Bug/Steel-typeGeneration VMythical Pokémon. Genesect was an ancient Pokémon that was revived and heavily experimented on by Team Plasma, turning it into a robotic creature with a cannon on its back. However, N abandoned the project saying that any Pokémon altered by science is "impure". The scientist working on the project, angered by N's decision, quit Team Plasma, created a lab, and continued altering Genesect until it escaped and was never seen again. Genesect's "signature move", Techno Blast, is altered by Hold Items called Drives that can change its type. The four drives are the Burn Drive, Douse Drive, Shock Drive and Chill Drive, and make the move's type Fire, Water, Electric, and Ice, respectively.
Genesect's name is likely a portmanteau of the words "genesis", meaning beginning because it is an ancient Pokémon, or "genetic" because of its altered genetic makeup and "insect" due to its is Bug typing.
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.
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.
Genesect is shown in a teaser after the pre-release of the fifteenth pokemon movie.
Even though Genesect uses its signature move, Techno Blast, Genesect doesn't receive STAB from it.
Genesect is the only prehistoric pokemon that is not a Rock-type.
