Rocksteady is one of the first major bosses you'll face, serving as a good introduction to boss mechanics. He has two primary attacks:

- Charge: Rocksteady will lower his head and charge across the screen. This attack is telegraphed by a brief wind-up animation.
- Ground Pound: He'll jump and slam the ground, creating a small shockwave that travels along the floor.
Strategy: The key to defeating Rocksteady is patience and timing. When he charges, simply dodge roll out of his path. He'll be momentarily stunned after hitting a wall or missing you, creating an opening for a quick combo. For his ground pound, jump over the shockwave. Avoid getting greedy with your attacks; land a short combo (3-5 hits) and then be ready to dodge. Special attacks are very effective for burst damage. In co-op, have one player bait his charge while others attack from behind. Keep moving and don't stand directly in front of him for too long. He's vulnerable after his charge and ground pound animations.
