The Sensei of the League of Assassins (DC Comics)


(League of Assassins)


The Sensei is one of the most dangerous martial artist in the DC Universe. He first appeared in 1968, and primarily clashed with Deadman and Batman.

These are older technical notes, not a full profile. IIRC, which I may not, it was part of a series of slightly refurbished Mayfair stats that had become difficult to procure.

Powers and Abilities

The Sensei is a devious, evil man. He has been leading a congregation of highly dangerous assassins for many years now. Nevertheless, he can always teach them new tricks and techniques. He is a cunning mastermind, and knows many things.

The Sensei is also an absolute master of the martial arts. It is rumoured that in his youth he threaded on paths Lady Shiva herself has yet to explore, and he might even be a match for Dragon. He is martially superior to such invincible legends as Batman or Ben Turner.


The Sensei first appeared as the leader of the League of Assassins, a secretive organisation of killers. The League’s goal is the utter mastery of all assassination techniques. They make themselves available at a steep price to practice those.

Entry into the League involves numerous conditions, among those at least one ritual murder. The best known such murder was the assassination of aerialist Boston Brand by the man called the Hook.

The League of Assassins is backed and partially funded by Ra’s al Ghul.

The ghost of Jonah

For a time, the Sensei was possessed by the powerful spirit called Jonah. Jonah, a man unjustly murdered, had seen his spirit picked up by the deity Rama Kushna. As such he was a predecessor of Deadman – a ghost able to possess living beings, among other feats. Jonah grew extremely powerful through the centuries. But he also came to revile Rama, who refused him his eternal rest.


Jonah possessed the Sensei, thus taking control of the League. That was part of a plan to destroy Rama Kushna so he could go free. Using the Sensei’s and the League resources, Jonah led an intricate plot to take over Nanda Parbat, Rama’s sanctum sanctorum. He was opposed by Deadman — Rama’s newer right-hand ghost — and at several points by Batman.

Jonah ultimately won. He invaded Nanda Parbat and confronted Rama Kushna. His power was such that they apparently destroyed each other.

Freed from the possession, the Sensei took some time to recoup his losses. Eventually, a rumour that he was no longer allied with Ra’s al Ghul made the rounds.

Free from desire

The Sensei of the League of Assassins should not be confused with the O-Sensei. The O-Sensei was a Japanese man living in China who was the teachers of such pupils as Richard Dragon, Lady Shiva, Ben Turner aka the Bronze Tiger, Batman, Green Arrow, etc. He died in the late 1980s.


Being possessed by Jonah gave the Sensei blue eyes like his possessor’s, but he presumably recovered his normal eye colour after Jonah was destroyed.
