Bizarro

Bizarro acts as an inverted version of the player character. "Bizarro" is only a nickname, as the entity does not have a true name or appearance. Instead, its name is displayed as the player's spelled backwards, and it renders as an upside-down version of the player character.

Spawning

Bizarro spawns as part of the Bizarro Spawn relog event¹ and will appear directly in front of the player who joined the game.

The Bizarro Spawn event will override all other relog events.

Behavior

Bizarro will stand still and stare at the nearest player. After anywhere between 10 and 30 ticks, it will despawn and send a player leave message in the chat.

If Bizarro takes any form of damage, it will immediately despawn and send a player leave message in the chat.

Notes

1. Bizarro also interacts with the player via the Bizarro Leave Message event and one of the sign messages. However, it is not physically present for these events.

Trivia

• The flipped rendering is implemented by momentarily switching the entity's name to "Dinnerbone" before it is rendered, and then immediately switching it back. This tricks the game into triggering the vanilla easter egg that renders mobs upside-down.
• The code for Bizarro refers to him as "Bizarro Dude".
• The concept for Bizarro came from a conversation on the Discord server for YouTuber Drapie.
