Anti

*you feel you're gonna have a bad time...

Anti is a post-warmode boss that appears as a large skeleton wearing a sky-blue hoodie and dark blue jeans. It can only be summoned if it is night and the player is in the dungeon. Anti has a lot of devastating attacks and abilities. If the player is unprepared, they won't last long. You summon Anti by placing an Eskimo Outfit, a Key of Night, and a Skeleton Skull in a chest.

The Battle
Please note that touching Anti will inflict 20 damage on the player.

Phase 1
In this stage Anti will attempt to hit you with bones flying from the walls. These bones do 50 damage each and will explode upon touching the player or another surface, doing the same amount of damage as a grenade. During this, as well as the rest of Anti's attacks, he is invulnerable. Between each attack you will have 10 seconds to strike back. Next, Anti will send bones running along the roof and floor in a wavelike pattern. Touching these bones will inflict 70 damage on the player.

Phase 2
In this phase Anti's left eye will flash blue and yellow, and he will cover the edges of the room in spikes. He will be able to cause you to emanate a blue glow, allowing him to fling you to the edges of the room. Anti will also be able to summon Skeletron heads that shoot blue lasers which do 400 damage. In this phase you only get 5 seconds to attack. There will also be a chance of blue bones flying from the walls, which do 70 damage.

This boss is a reference to Sans from UNDERTALE.

The Skeletron skulls are references to the Gaster Blasters, which actually look more like turtle skulls...

Anti is a near-synonym to the word sans, meaning without.
