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.
