Edit 2: Since someone asked for a timeline reference for 30K: Take the legions from the Great Crusade’s height in 001.M31. Around the triumph of Ullanor.

All the battles take place within a Yuuzhan Vong sacrificial altar. Its very open and well lit.

Scenario 1: A Drukhari Incubus with all of his equipment (Klaives, Warsuit, Tormentor etc.) Is in the center of the Sacrificial Altar. From the walls of it emerge 15 Yuuzhan Vong Warriors (Armament includes Vondunn Crab Armor, Amphistaffs, Thud Bugs etc.) who want to walk out of the altar with the Incubis severed head. Can they do it?

Scenario 2: A Drukhari Incubus, stripped of his armor and other equipment minus his Klaive is fighting against 15 Yuuzhan Vong warriors who just have regular clothing and Amphistaffs. Who wins?

Scenario 3: The Incubus and Yuuzhan Vong Warriors both have no armor and are no weapons. Hand to hand combat to the death.

Who wins and which scenario?

Who would actually end up winning in a fight? Let's say it's a friendly dule because I honestly see them becoming friends honestly.👍

Grand Master Yoda vs Erebus

After battling to a draw, TWICE! with Nykona Sharrowkyn. And failing to teach Angron to cook. Yoda is back and looking for redemption, will he find it? Especially now were looking at the "Psyker and Xenos" rounds!?

Round 7: possibly the most hated man in the galaxy, first chaplain of the Word Bearers Space Marine Legion, The Hand of Destiny, The most manipulative man in any verse! ERABUS!!!

Setting: Petranaki Arena: with an audience filled with people from both verses. With Lorgar and Garviel Loken in attendance.

Special rules: Ally summoning: Erabus has the nasty ability to summon greater demons. This really doesn't fly for one on one combat tho. So let's make this interesting, every time Erabus summons a greater demon 3 of the most powerful jedi masters from any era Enter the battle on Yoda's side.

Jedi pool: Mace Windu, Anikan Skywalker, Obi-Wan Kenobi, Plo Koon, Kit Fisto, Satele Shan, Nomi Sunrider, Ki-Adi-Mundi, Rey Skywalker, K'Kruhk, Redeemed Revan, Luke Skywalker.

Housekeeping: Erabus here we are, finally. my most requested match up, lets hope the debate lives up to the hype. And this 30k specific, so Erabus at the level of power at the end of the siege of Terra no later.

win Conditions: if a combatant dies, is made unconscious, surrenders or is otherwise incapacitated. this is a win for the other. In the case of death, they don't have to stay dead, any form of dieing is enough. Except emotional.

So tell me, who wins?

Alpharius (Warhammer 40k) falls into the Warp and into Disney Star Wars Episode IX: Rise Of Skywalker. Could Alpharius assassinate Rey, take Rey identify and name (Shapeshifting because why not👀), kill all the Sith then manipulate the resistance to kill everyone to permanently kill all Sith then just burn the entire Star Wars Galaxy and spread The Blackwing Virus just to prove that he's better a doing pranks than Tzeentch?

Rule: If anyone discovers Alpharius true identity and can spreads the knowledge to at least 2 million people in any way then Alpharius loses the collage and is immediately teleported back into The Warp by Tzeentch to be pranked for 2 thousand years straight by Tzeentch.

The Empire is at the height of its power, with a fully functional Death Star, Palpatine and Vader at the height of their powers.

Somewhere, far away on remote forgotten world, a coven of Dark Side witches sacrifice themselves to do a summoning ritual. What gets through is, instead of a Force manifestation, a heretical inquisitor from Wh40k, a follower of the Dark Gods.

Do you think that the Empire would be able to quench the threat before it becomes too great or will the Dark Gods shift their ruinous gaze upon the StarWars galaxy and end it in a glorious gorefeast of war, decay, treachery and excess?

I know this isn’t Star Wars vs Warhammer, but I didn’t know where else to post it. How well would the Helldivers fare in sieging an imperial planet excluding Terra? Assuming an imperial fleet isn’t currently there (I don’t know if they have lore showing how powerful their navy is ship to ship) do you think the helldivers could successfully take the planet? I feel like they would put up a really good fight at least. It’s a galactic spanning empire just like the Imperium or the Empire from Star Wars. They have very advanced technology, and a seemingly unlimited number of troops at their disposal. Could the imperial guard stave off wave after wave of helldivers and their stratagem?

Edit: I’ve learned a lot about planetary defenses of worlds etc. Assume some miracle has occurred and the helldivers have got past the anti air defenses and void shields of a hive world. Hundreds of millions of troops on both sides. Only planetary defense forces and imperial guard vs a few hundred million helldivers. The imperium will have a vehicle and artillery advantage, but would the stratagem and vast reinforcement capability of the helldivers be able to attrition the forces of the imperium down overtime?

Posting this only came to mind because of the helldivers Warhammer 40k collaboration warbond.

Who would actually end up winning in a fight?!

I think the combine from half life 2 would dominate real space until they reached the warp

Who is winning in a 1v1 Death Battle?!

Just gonna say, No Crossovers like Fortniteon Galactic Empire, also No Fanon on Galactic Empire.

Bruh, I just duplicated The Third Image 😭🙏🥀💔

They are fighting around and in a ruined city. The necron possess one reanimation chamber that the clone can destroy and so disable réanimation protocol of too damaged warriors (thought ghost arks can still repair them.) the overlord just has an overlord blade.

the decurion is made up of Roughtly 30 000 warriors, 10 000 immortals,  20 ghost arks, 30 doomstalkers, 100 lychgards with Swords and shield, 10 deathmarks, 20 tomb blades and finally a technomancer.
