Sir Rothchild

"Haha, you didn't think I would miss this, dear chap. To Victory!"

- Sir Rothchild to Jack in Samurai Jack: Battle Through Time.

Sir Colin Bartholomew Montgomery Rothchild III (shortened to just Rothchild) is an ally of Samurai Jack and part of a group called The Canine Archaeologists. He was introduced in Episode II: The Samurai Called Jack.

Personality
Rothchild shares the same personality as his group, the archaeologists, who are passionate about studying their past. Rothchild and his colleagues are intelligent and well-mannered but retain habits from their ancestors, like riding a vehicle with their heads out the window or wagging their tails when happy.

Appearance
Similarl to his fellow archaeologists, Rothchild resembles his quadrupedal ancestors (in his case, dauchsunds) in size appearance and certain characteristics, such as wagging their tails. Rothchild and the archaeologists gained the ability to walk upright, use their front paws as hands, complete with opposable thumbs, enhanced intelligence and the ability to talk fluently. After fifty years, he grows a beard.

Biography
Rothchild and the canines first appear in the bar Jack enters to find a drink, trying to convince an alien to help them fight against Aku in order to free themselves of his grasp. The alien calls them idiots and leaves, so they turn their attention to Jack, whom they had seen defeat a large number of aliens without taking a hit. Rothchild and the canines introduce themselves to Jack, and help explain to Jack his current situation, and that they need his help. Jack accepts and the group leaves, though they didn't realize that they were being watched by one of Aku's servants. The servant informed Aku and Aku sends an army of Beetle Drones to destroy Jack and the canine.

As they reach the excavation site, Jack, Rothchild and the canines learn that Aku is sending his forces to obliterate them at sunrise. Jack comes up with a plan to stop the advancing horde, and with the help of the dogs, sets up various traps and makes some weapons to fight. As sunrise comes, Jack heads into action. Using the traps and his new weapons, Jack manages to wipe out a large number of drones as the Canines watch from their hiding places. Eventually, Jack defeats the last of the drones, freeing the canines and enabling them to continue their research. Rothchild and the rest of the group offer Jack a chance to go with them, but he declines and goes on his way.

Rothchild and the canine archaeologists make a cameo in Episode XLIII: The Aku Infection.

Season 5
Sir Rothchild make his return in Episode CI with a sizeable family of dauschunds that resemble him. He and his family witness Aku's triumphant broadcast and immediately assault The Pit of Hate with Jack's other allies using their flying vehicles. Some of his family members are taken down by Aku's corrupted forces, with Rothchild himself shot down after his ship is damaged damaged by Aku's rain of spikes.

It is unknown how the past Aku's destruction affects his existence and or those of his fellow canine archaeologists.

Battle Through Time
In the pocket between time Aku created, Rothchild is restored to his original appearance, and finds himself in Aku's Mines being chased by Beetle Drones once again. After slaying the Beetle Drones, Samurai Jack asks him what was going on. He tells the Samurai that he does not know but has seen the Scotsman in the adjoining swamp. He continues to provide Jack with items and advice throughout the game. During the final battle at Aku's Tower, he bombs the army of Beetle Drones below from his hovercraft and gives Jack a final salute.
