All Ender Dragons share a variety of attacks and behaviors that they use periodically, which are split into "Standard" and "Desperate". Standard attacks will be used at all times by all Dragon types. Desperate behavior/attacks will only be used if either:

• The Dragon is the vanilla Ender Dragon type
• The Dragon is Ominous
• There are no remaining End Crystals

Standard

• Slam. The Dragon slams its whole body down on the ground, creating a damaging explosion in the surrounding area, before quickly rising back up to altitude
• Summon End Rod Spikes. These work similarly to Evoker Fangs, and are summoned when the Dragon is perching or preparing to perch, or as a last resort
• Summon Shulker Bullets. This summons a ring of 12 Shulker Bullets around the Dragon, which will begin to target random players after a few moments. If there are already Shulker Bullets in the area, it will summon End Rod Spikes, instead

Desperate

• Ground all players. Whenever the Dragon selects any attack while Desperate, if there are any flying players, it will give all players high gravity for 20 seconds, forcing them to (safely) land if flying with Elytra, and preventing them from taking off right away
• Meteor Storm. An additional attack the Dragon can select while Desperate. Summons a volley of Dragon Fireballs in the sky over the course of several seconds that cover the arena in Dragon Breath Clouds. If the Dragon is a Warped Dragon, this also removes any existing Dragon Breath Clouds
