What the Doom marine sees when he is invulnerable, Hell Revealed MAP14

The invulnerability is a powerup that makes the player generally impervious to damage for 30 seconds. The player is not protected from telefrags, and will still recoil from a successful attack. The powerup looks like a green sphere with a grinning head inside. While it is active, the colors in the player's display change to inverse monochrome, and the eyes of the status bar face glow yellow, making them look similar to the Demon's; in the last few seconds the display will begin blinking back to its original colors.

Invulnerability can also be activated with the cheat code idbeholdv.

In deathmatch mode of vanilla Doom, invulnerabilities and blur artifacts never respawn. Some source ports allow flags to be set to cause them to respawn.

Invulnerabilities are included in the items percentage displayed at the end of each level.

Notes

The grinning face inside the sphere appears to be derived from the Lost Soul sprite in Doom 0.4. Oddly enough, the invulnerability sphere in that version of the game was invisible and had an unused sprite in the IWAD which looked like a giant health bonus.
