Stunlock

Bosses are usually immune to this regardless if there is no stunlock breaking abilities, actions, or such available otherwise.

This is usually intentional (at least if there's ways to counter it), but for vs fighting games this is likely a design flaw .

If this is only possible via using abilities with cooldowns and using them from multiple characters/units in sequence, then this tag is not so interesting as all it requires is that there's even one ability that produces a desirable effect for stunlocking and a number of players can use it in sequence.

In multiplayer games this is usually quite intentional and may have some form of counter play in place.
