You can Shove and Grapple as bonus actions. When you knock someone prone, they have to spend their full movement to stand up. If they have an ability that allows them to stand from prone for less than half their movement, they have to spend half their movement to stand when you knock them prone.
You can make Athletics and Intimidation checks with advantage. Creatures who enter your melee range for the first time must make a wisdom saving throw or become frightened until the start of their next turn. The DC for the save is 8 + your proficiency bonus + your strength modifier.
You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.
Your large hands make for natural weapons in dire circumstance. As an action, whilst wielding no weapons, you can use your fists to slam your opponent for 1d8+ Strength Modifier in bludgeoning damage. This can be repeated as a bonus action on the same turn, given that no weapons are being wielded.
