Minecraft wiki entry for Vindicator, associated text: If the vindicator has no weapon (its axe), it still attacks players, iron golems, villagers, wandering traders, and snow golems, except the axe doesn't appear in the vindicator's hand when the vindicator raises its hand.‌[Bedrock Edition only] In Java Edition, a mainhand-unarmed vindicator raises both of its hands when attacking, similar to a zombie. A vindicator's axe can break, just like pillager crossbows.‌[JE only]
