P-1 Grand Prix Tournament
In the first round of the P-1 Grand Prix Martial Arts Tournament, Brock's Geodude was up against Giant's Hitmonlee which was under the control of Team Rocket. It took a mainly defensive approach and was no match for Giant's Hitmonlee's constant kicking. Brock decided it was best to forfeit the match by throwing in the red towel.
