In Dexter's Laboratory
Huntor is presumed to be the same character who appeared in the Dexter's Laboratory episode "Huntor." There he refers to himself as "the greatest hunter in the universe" and hunts rare animals across the universe. He utilizes various weapons, such as his trusty alien (or possibly robot) mount Snorkdro, heat-seeking moisture missiles, an "ampliphaser," a powerful force field, a negative ion blaster, "good old-fashioned lead" bullets, a Monkey Emission Sensor (or EMS), and a big gun that is easily twice his length, complete with a massive scope and harpoon launcher.
In Samurai Jack
In "Episode VIII: Jack versus Mad Jack", Huntor appears atop his mount Snorkdro, who appears to be replaced with a robot facsimile (assuming the original was in fact an alien). His gun also appears different from the dozens of weapons he wields in Dexter's Laboratory.
When he first appears, his strategy is to shoot energy beams from his gun while riding Snorkdro, however the beams are easily deflected by Jack's sword, one of which hitting him and knocking him to the ground. His next strategy is to have Snorkdro trample Jack, but Jack simply raises his sword and slices Snorkdro's belly open, causing the robot to explode. Huntor then gets scared, making a cat-like noise and running off much like he did at the end of the Dexter's Laboratory episode.
