Klamath Osler


Klamath in chapter 5 of Yu-Gi-Oh! R

Klamath Osler 「クラマス・オースラー, Kuramasu Ōsurā」 is the third Card Professor who is obsessed with his luck. Jonouchi defeats him. He is named after Klamath Falls, Oregon.

He also seems to know Kirk Dixon, mentioning him when he meets with Joey and Tristan. This is futher supported by a picture of himself and Kirk operating remote-controlled toys, based on the monsters that they use.

Klamath uses an Insect Deck that centers around his Antlion.
