Some people think Ditto is a "failed" clone of Mew for the following reasons: 1. They are both pink. 2. They both know transform. 3. They have the same weight. (8.8) 4. Ditto appears to be a lab-experimental glob. 5. It was said that Mewtwo was the only SUCCESSFUL copy of Mew, meaning Ditto could have been a failed copy.
