Montgomery participated in the Don George Donamite Tournament. He is very snooty and thinks he is superior to everyone. He is well dressed and well groomed though but that is part of his upper crust mentality. He likes to scout out his opponents by studying and spying on them to learn about their tendencies and weaknesses so that he can exploit them to his advantage. Montgomery's Throh has picked up on Montgomery's attitude and the two of them seem to be able to play off of each other without actually having to speak as it was evident when Montgomery's Throh tried to intimidate Stephan's Sawk.

Donamite Tournament

In the first round of the Donamite Tournament, Montgomery faced Delbert. Montgomery's Throh faced Delbert's Mienshao and showed its incredible strength by using a three move combo: Superpower, Seismic Toss and the finishing move Circle Throw. Delbert's Mienshao was knocked out before it was even able to land a successful blow. With the win, Montgomery advanced to the second round while Delbert was eliminated from the tournament. At that point in time, Don George had Montgomery at the top of his list of favorites for the championship.

In the final round, Montgomery's Throh was finally matched up against Stephan's Sawk. The two had been taunting each other throughout the tournament and the fight lived up to the anticipation. The two trades blows until Stephan's Sawk was able to land a very powerful Close Combat that Montgomery's Throh was unable to block. Realizing that it had won the match, Stephan's Sawk bowed and walked away as Montgomery's Throh tried to continue but was knocked out. The victory eliminated Montgomery from the tournament and Stephan was declared the victor. Montgomery was surprised to have lost the tournament, but he showed his humble side and shook hands with Stephan, accepting the loss. He told him the next time they fought he would win and Stephan said he'd win again.
