The Whiplash is a brand new demon appearing in Doom Eternal.
The Whiplash is a Cybrid+Insectoid demon, with two thin horns curving up and backwards over its head, where its brain is exposed. Its arms are covered in what resembles long, black gloves and wields a chain whip ending in a curved blade, hence its name. From its abdomen down, the Whiplash's body is cybernetic and snakelike. Not much else is known about this demon other than its name, which was revealed on Twitter.
