The vindicator's appearance in Minecraft Dungeons is similar to its default counterpart, but with a slightly brightened texture, and their arms are never seen together, unlike in the original game.

The 1st variant is a vindicator that has gold buttons, a smooth metal helmet and purple pants and wields a double axe; meanwhile, the 2nd variant is a larger (2.7 blocks tall) vindicator that has diamond buttons, a horned metal helmet and blue pants and wields a whirlwind axe.
