Hoopa is a Psychic & Ghost type, which is actually a cool typing, although it has a glaring ghost weakness. Now, the thing about Hoopa I like least would be the design, it just doesn't stand out to me at all like other mythical designs do. However, Hoopa does have alright stats, alright abilities and an okay movepool. The redeeming thing about Hoopa would be its form, Hoopa-Unbound, which is Psychic & Dark type, has a better design than regular Hoopa, and has better battling capabilities due to the stats and type combination, still need to be wary though, since Hoopa-Unbound has the 4x weakness to Bug. If I was ranking just Hoopa-Unbound by itself, it'd be a bit higher, but regular Hoopa just weighs it down a fair amount, and Hoopa I would honestly say might be my least favorite mythical of them all, only maybe edging out Phione from Sinnoh.
