There are a variety of things you can look at to determine if a Pokemon is hacked or not.
- You can check the Pokemon's page and see if all of its moves are legal. (Such as a Metapod having Outrage.)
- If it is an event Pokemon, you can look up that Pokemon's event to see the date it was received was correct, as well as the OT ID.
- You can again check the Pokemon's page, and look to see if its stats are illegal or not. (Such as a Blaziken having 999 Attack, 999 Defense, 1 Defense, etc.)
- Check the Summary of the Pokemon and see if anything looks fishy.
There are a ton of things you can do, but it would be more helpful if you could provide the Pokemon's details itself in this question.
