So many FT villains are (or looks like) under 30.

- Team Lyon of Galuna Island arc

- Jellal and some of Tower of Heaven

- The whole Team of Laxus from Battle of Fairy Tail arc

- Oración Seis (except Brain and maybe Hoteye) from Oración Seis arc

- 7 Kin of Purgatory (except maybe Kain and maybe Azuma)

After the timeskips it gots not better.

- Team Sabertooth (except maybe Minerva)

- Kurohebi and Flare from Raven Tail

- Mary, Jerome, Gray (actually a spy), (maybe) Briar from Avatar

- The new antagonists except God Serena and Orgast.

Justified, Fairy Tail isn't the only one anime, as we know.
