|“||A rugged warrior sent from the isolationist planet of Oh! Edo to join Bill Rizer in his fight against the Neo Contra. Despite carrying on the samurai code of ethics and combat techniques, Jaguar insists, "The sword is the final weapon." His full name is Yagyu Jaguar Genbei.||„|
|~ Official background|
Genbei "Jaguar" Yagyu (柳生・ジャグワァ・玄兵衛 Yagyu Jaguwa Genbei?), commonly referred to simply as Jaguar, is a mysterious human/alien hybrid who follows the code of the samurai. He is Bill Rizer's partner in Neo Contra and Contra ReBirth.
In Contra ReBirth, with the help of Plissken, a lizard-like alien, BR-W9, a robot, and Lance Bean, Bill's old partner, Yagyu manages to take down the Neo-Salamander Force. However, Chief Salamander was nowhere to be found. In the true ending of the game, it is revealed that Chief Salamander is actually Plissken, who infiltrated the Contra unit under an assumed name.
- Jaguar is from "Oh! Edo", a planet where humans are relegated to live in, as they are not allowed to go to Earth. Justified since the space colonization policies took place before the events of Neo Contra.
- Yagyu Genbei is based on legendary samurai Yagyū Jūbei Mitsuyoshi.
- According to the legend, Jubei could only see with one eye and is therefore sometimes portrayed wearing an eyepatch. Fittingly, Jaguar has some kind of optical enhancement attached to his left eye, clearly meant as a reference to this eyepatch legend.
- According to the official site of Contra: Return, Senbei Yagyu is Jaguar's ancestor. However, it should be noted that all events in this game take place in an alternate universe, different from those in the original timeline.
