They're both genetically-engineered unstoppable psychic powerhouses who were created by science in an attempt to recreate the power of a legendary psychic being, Mew and Akira respectively, and were the first successful products of the cloning process. However, they ended up escaping from the places they were made in and went on a rampage. Eventually, they fought a battle with the being they were made to succeed. While Mewtwo was a clone of Mew from the start, Tetsuo was originally a human who was engineered to gain Akira's powers by the government, and while Mewtwo was trying to find its place in the world, but became evil due to its status as a genetic experiment, Tetsuo just went mad with power and decided to try and release Akira from his imprisonment.
