The One-Two (ワン ツー, Wan Tsū) is a combo that consists of a jab and then a straight. It's a basic technique that all boxers use. The one-two is commonly used towards the opponent's head, but it also can be used as a body blow, as seen when David Eagle used the one-two on Mamoru Takamura, aiming at his body.

Trivia

• Genji Kamogawa states that Eagle's one-two is considered to be the strongest in the world.
