Arguably the most powerful martial arts in Japan.

An Aikido practitioner is practically invincible, no one of any martial arts background can ever land a punch or kick on one.

Using the power of the attacker, the Aikido practitioner uses absolutely no energy to knock them down.

A fearsome martial arts it is.

But because of it, it's entirely useless offensively; it's the Wobbuffet of fighting styles.

Also it doesn't deal with kicks as efficiently as punches.
