There are a few Iso Bots you can battle:
Like the name says, the Iso bot that has *ev* helps with *pokemon* *ev* stat.
The Iso bots are widely used, especially the regular Iso bot and the Iso_Speed.
The Iso bots have level two pokemon in their teams, except Iso, who has a full team of level 100 Audino.
Iso uses Audino, which when fainted gives 14 thousand exp, comparable to Aegis MKII.
