Bonsly

Bonsly is by no means bad; it just has no place in Little Cup. One might say that it is completely outclassed by Geodude, which has higher Speed, access to Stone Edge and Earthquake (both of which Bonsly lacks), and a better physical movepool, with powerful moves such as Superpower. Bonsly's pure Rock typing, however, leaves it less vulnerable to the many weaknesses given by Geodude's Rock / Ground typing. Bonsly's Attack is high enough to attempt a sweep, and its even higher Defense gives it opportunities to set up, traits other pure Rock-type Pokemon such as Nosepass and Roggenrola lack. Bonsly even has Rock Head, which makes Double-Edge a good attacking move. Ultimately, if your team supports Bonsly enough, it can wreak havoc.
