Are there any champions with a stagger effect to damage?

Similar to death's dance in taking some of the damage initially and the rest over time?

Going to use as my example.

uses W which causes him to stagger 50% of all damage he takes over 5 seconds. If somebody hits him with an ability that deals 500 damage, Gragas takes 250 damage initially and 250 damage over 5 seconds(50 damage every second).

I play WoW and there is a tank spec called brewmaster that has a similar mechanic in staggering damage they take over time. I was thinking a similar mechanic for a tank steroid would be kinda cool.

Or maybe it could be used for a melee adc in where they activate this as their ultimate and instead of staggering damage, they go into a sort of negative health while unable to die but every damage they do "heals" the negative health on a 1:1 ratio. So if the champion has over 5000 negative health but they do 500 damage every auto, they remove 500 negative health with each auto. If they get rid of the negative health by the time the ult ends they heal up or something.
