Both have standard wargear.

The Death Company Astartes has just walked in on Atriox relieving himself on a statue of Sanguinius.

Unified Humanity is given 125 years to prepare against a no holding back United Covenant Empire.

• United Covenant Empire doesn't have infighting.
• Halo arrays can't be used.
• Unified humanity trust each other completely while sharing Knowledge, Technology, secrets and more.
• Mass Relays can be found all over the galaxy.

I've just been thinking about ways to give other Xenos factions more lore. I can't help but feel like you could just add hulking gorilla-type Xenos into the Tau, then simply make Space Marine stories but with a friggin Tau monkey in Fire Caste plate interacting with Gue'vesa (Tau Humans) & other Fire Caste. Plus I think it could show some cool potential lore for how Ethereals deal with a more physically demanding species that may not necessarily agree with the Ethereals "Greater Good" interpretations 100%

I don't think this theoretical species should be as strong as Space Marines by any means btw, and it doesn't have to be Jiralhanae themed. But they would out-number Astartes as a species and could likely send a few more of these Xenos Hulks than the Imperium could send Astartes.

But I just thought it would be cool & fairly easy having a species that truly resembles Astartes & their fighting techniques, that way it's not just Loyalist vs Traitors 24/7. However if the Tau found out about Tarrellians (Hurons Bounty Hunter) & recruited them / use them as kroot grub, that could make for a sufficient scaley variant as well.

I also know without a doubt that this is some dumb cop-out answer to give Xenos more stuff. But idk it feels weird that factions have "Astartes Equivalencies" but nothing that ever quite feels like Astartes or quite matches up. I know Human Space marines are a seller, but I feel like Tau fans would buy into the idea and enjoy having their own variant..

Also, I have to assume modeling/painting all the the appendages and upgrade sprues with fur where it's unarmored, would be a pain in the ass. Though I still believe a sizable number would be willing to add it to the pile.

Atriox will be armored in his Modified Combat Armor (Dont know what its called I assumes its modified because from what I have heard his armor is a mix of unsc and covie stuff), while being equip with chainbreaker and a power gauntlet.

The deathwing knight will be armored in Indomitus Terminator armor while being equip with a stormshield and a mace of absolution.

Who wins in this melee fight?

zealot or black Templar

In this match up, we have no space for blood and battle (mostly). In the left corner of the ring, sizing just over three meters tall and weighting around a ton, we have Guk the ogryn! A loyal servant of the emperor and just a good fella!

In the right corner of the ring, we have 2 brutes, whose name shall never be remembered cause they are filthy xenos. Weighting 510 and 680 kg, and 270 in height!

The battle today will Comanche behind the table filled with pounds and pounds of food. Which team will out eat the other?

Round 1) they just sit behind a table and eat all they can in the ring.

Round 2) ogryn has the commissar explain to him that he can't eat the brutes

Round 3) the commissar tells ogryn that the emperor is cheering for him.

Round 1: 15 Minutes of time control.

Round 2: 5 Minutes of time control.

Round 3: 1 Minute of time control.

White pieces: Cortana

Black Pieces: Azrael.

Both sides gets to have 20 minutes of learning chess such as its rules, tactics, strategy, openings, techniques, etc.

None of the three can get out of their vehicle or fire their weapons (they are not permitted to attack each other while refueling, eating, or resting).
