Yes and no, during the boss rush event you can activate his passive in every boss fight, i used his passive about 4 times in the final boss rush stage.

Basically it lasts per fight, if you have to fight 3 times and loose 30% health in the first, and 45% in the second (25% health left), whis will revive health in the second and when you go into the third fight his passive will be available again.. he is very useful if you have multiple fights in 1 event (omega shenron) but if you have only 1 fight then there is better units..
