Rag Mega

Rag Mega is a boss added in The Binding of Isaac: Afterbirth † that can appear in all environments of Chapter 2.

Behavior
Rag Mega spawns with 3 Purple Balls which are immune to damage and block shots. They circle around him as he floats around the room while he performs the follow attacks:
 * Each time Rag Mega loses around 25% HP, he breaks off a Purple Ball which starts to chase Isaac.
 * Periodically wraps his body in bandages and becomes immune to damage.
 * Spawns a Rag man's Ragling. They will leave remains on the ground after death.
 * Fires 3 beams from the sky that travel outwards. If the beam hits the remains of a dead Ragling, it is revived.

Trivia

 * It appears to be an "evolved" variant of Rag Man.
 * Rag Mega looks and behaves similarly to The Duke of Flies.
 * Although it is an upgraded version of Rag Man, it has 80 less health.
 * This is likely due to the fact that Rag Mega can become invincible for extended periods and has tear-blocking Purple Balls, making him harder to damage.
 * Rag Mega doesn't have a death animation.
