In the original games, Mewtwo is intended to be "the strongest Pokémon ever". Due to genetic engineering being applied to a sample of Mew's DNA in order to fully create Mewtwo's genome, Mewtwo is an extremely powerful psychic, yet its abilities surpass Mew's due to intentional alterations to the genetic source material. As such, it can use telekinesis for flight, to shield itself, or to powerfully throw opponents aside. In addition, it is among the very few Pokémon capable of human speech, which it does so via telepathy. Otherwise, it conserves its energy until needed, such as against powerful opponents. In addition to its psychic abilities, Mewtwo can also regenerate, which allows it to quickly recover from near-fatal injuries. However, Mewtwo notably lacks Mew's ability to learn every single teachable move within the games.
