Mightyena is a pure dark type, and has an okay design, not really too much exciting though with its design. Other than that, Mightyena is average when you look at its stats & movepool, but it's decent when it comes to its abilities. Mightyena is a pokemon I definitely wouldn't rely on too much with battling though, as it is a bit weak overall, which is mainly why I ranked it here. I do generally find Mightyena to be an okay pokemon though, just wish it was more viable to use in the games.
