The Terminator is summoned when all three Mechanical Bosses have been defeated and using the Sigil of the Terminator. The Terminator is a Hardmode boss. It is suggested to use a Solar Eruption to defeat this boss. The Terminator shoots a Super Deathray (400 Damage) that can wipe out players easily, and Death Bullets, dealing 10 damage each. The Terminator has 150000 total health points, including 10 defense.

When the Terminator kills a player, it displays the unique death message "[Player Name] evaporated into dust." All of the Terminator's attacks give you the On Fire! debuff for 10 seconds.
