There are multiple statuses you can apply on enemies in Marvel Rivals. This article explains them.
Earthbound
When applied to an enemy, it restricts their high mobility abilities like dashes. If their ultimate involves such movement, the ultimate will be disabled as well. E.g. Magneto’s Meteor M (when Mag is earthbound before using the ult of course).
Example ability: The Thing’s Yancy Street Charge.
Notable exeption: Namor’s Blessing of The Deep is not counted as a movement ability. His bubble is not being blocked by Earthbind.
Grounded
When applied to a flying enemy, it restricts their aerial abilities. In other words, they are falling from the sky.
Example ability: Thor’s Lightning Realm.
Immobilized
When applied to an enemy, it does not allow them to move at all.
Example ability: Star-Lord’s Flora Munitions.
Invincible
When a hero is invinsible, he can be damaged or stunned in any way.
Example ability: Gorr’s Living Abyss.
It is also the property of i-frames.
