That Pokemon is Porygon 2. There are two trainers who have him, although you may have already gotten past the Scientist in the Galactic HQ. The other one can be found on Route 216. That is one of the Snowy Routes. The trainer is Ace Trainer Blake.
You may need to find a trainer who has an Unown (sometimes wrongly spelled as Unknown) to complete your Pokedex. You can find someone who has it in the Solaceon Ruins.
