Ubu

Ubu is the servant of Ra's al Ghul.

History
When his master planned to hijack a rocket, Ubu stood guard at the launch pad. He intercepted Batman, and with his superior strength pinned him against a tanker truck. He was defeated by Robin, who swung the fuel hose around his leg and jammed the gas pedal. Ubu was dragged away.

He managed to recover, but it was too late: Ra's al Ghul had perished, after falling from the top of the launch tower. Ubu carried him away, and urged Talia to follow him. As their plan had failed, they retreated.

Ubu helped Sensei with reviving his master in the Lazarus Pit. As Ra's rose, Ubu approached to support him, but was beaten back by Ra's, who was enraged as a side effect of the reviving process. Ubu would not hear his master's apology; he instead apologized himself for not being able to stop Batman.
