Baron of Hell/Doom Eternal

The Fireborne Barons are a new breed of the Barons of Hell from Doom (2016) and make their appearance in Doom Eternal in the place of the ones from 2016. Despite being a different breed according to the Codex, they are fundamentally identical to the 2016 Barons, but with an altered color scheme, as well as being stronger (being able to survive a single BFG shot) and having a more aggressive AI, making them tougher to take down.

Background
Codex Description:

''The Fireborne Barons have evolved, the descendant clan of the Baron hell breed, and are indigenous to the caustic, scorched hellscapes bordering the Burning Abyss. A landscape of cragged spires forged from unbreakable Blackstone, tempered by the crashing waves of the magmatic tide, these sulfuric planes of Hell have long served as banishing grounds - a place of the exodus to which the damned are sentenced as their final destination. The Fireborne Barons have evolved in this environment, sustaining themselves on the remnants of the damned, growing obsidian carapaces and in time becoming infused with the very incendiary matter of Hell itself.''

Physical Appearance
The design of the Fireborne Baron is very similar to the 2016 Baron, being a muscular, goat legged demon with a build similar to that of the Hell Knight from Doom 3. The main difference is in the Baron's color scheme, as the Fireborne Barons, instead of being red and brown, are now all grey with a magma effect around its body. The most notable addition to the Baron's design is now they have two fiery blades emitting from it's arms, similar to the energy blades of the Dread Knight. When the Baron gets damaged in battle, the damage exposes its skeleton, which underneath has a bright, magma-like glow.

Combat Characteristics
The Barons function nearly identically to their Doom (2016) counterparts, but are much stronger and durable, even able to withstand one BFG shot, and are completely immune to the chainsaw (owing to them requiring five pips in the previous game, and Eternal's chainsaw only having three). The Chaingun and Rocket Launcher are now more effective than ever in dispatching them, similar to the classic games.

Interestingly, during the encounter with one in the QuakeCon Phobos footage, the player was able to repeatedly knock back and stun the Baron with melee attacks. Whether this was a cut mechanic or an early version of the blood punch is unknown, but is not possible in the final game.
