Horus Vs Abaddon

Now, there is much hatred directed against Abaddon on this wiki, but now we shall show him vs Horus in a one on one duel to the death. Now, to make it fair, we are going to use Abaddon should he ever arrive at Terra- i.e hyped up on Chaos Power. Thus we are counting him as having every single chaos reward from the table.

Maxed out Abaddon vs Maxed out Horus

To make things fair (and reduce the 240pts gap between Horus and Abaddon) we will be granting Abaddon every single attribute on the chaos boon table, as well as assuming that whoever was using him as not a dolt who stuck fleshbane on the Talon of Horus. This gives him the single most powerful weapon in 40K (Drach'Nyen- +D6A, AP2, Fleshbane, Instant Death, Shred, +1S, Poisoned). Also, as they are evenly matched (As seen below) we will be comparing bodyguards.

Maxed out Abaddon

WS8, BS6, S5, T6, W5, I7, A5, Ld10, 2+ re-rollable armour save, 4+ Invulnerable Save

• Talon of Horus - Sx2, AP3, Shred, Poisoned, Instant Death,
  • Ranged - 24" S5 Ap5 Rapid Fire, Twin Linked
• Drach'Nyen - S+1, Ap2, Daemon Weapon, Fleshbane, Shred, Instant Death, Poisoned

• Abaddon has Eternal Warrior, Feel No Pain, Rage, Counter attack, Fleet, Shrouded, Hammer of Wrath, Crusader, Hatred (All), Preferred enemy (Space Marines), Fearless, Stubborn, Adamantium Will, Additional rules (Witch Eater, Icy Aura)

Maxed out Horus

WS8, BS5, S7, T6, W6, I6, A5, Ld10, 2+ Armour save, 3+ Invulnerable save, 3+ Save vs affects that would modify characteristics aversely

• Worldbreaker - S10, AP2, Master Crafted, Concussion, Unwieldly
• The Talon - S user, AP2, Shred, Disabling strike (Any model wounded but not slain -1WS and -1S)
  • Ranged - 24" S5 AP3 Assault 3 twin linked weapon

• Horus has Eternal Warrior, Fear, Adamantium will, Fleet, Fearless, It Will Not Die, Master of the Legion, Weapon Mastery (allowing him to split attacks freely between weapons)

Crunch

Assuming both are in a stand-up fight, so no charges, no shooting beforehand, this is just a straight-up mathhammer showdown:

• Abaddon's Round 1: 9.5 attacks (5 base, +1 for two specialist weapons, +3.5 from his sword), hitting 7.125 times, causing 6.927 wounds, 2.309 going through Horus's Invulnerable save, 1.976 after IWND.

Abaddon's Round 2+: 9.5 attacks (5 base, +1 for two specialist weapons, +3.5 from his sword), hitting 4.75 times, causing 4.618 wounds, 1.539 going through Horus's Invulnerable save, 1.206 after IWND.

Special note, Abaddon will not ever need a 5+ to hit Horus as he will be dead before his Weapon Skill drops to 3, and he always wounds on a re-rollable 2+ so that won't matter either.

• Horus (Worldbreaker): 6 attacks (5 base, +1 for two CC weapons), hitting 3.5 times (thanks to Master-Crafted), causing 2.917 wounds, 1.458 going through Abbadon's Invulnerable save, 0.972 going through Abbadon's Feel No Pain save.

Horus (Worldbreaker, after causing one wound with The Talon): 6 attacks, hitting 4.5 times, causing 3.75 wounds, 1.875 going through Abbadon's Invulnerable save, 1.25 going through Abbadon's Feel No Pain save.

• Horus (The Talon): 6 attacks, hitting 3 times, causing 2.666 wounds, 1.333 going through Abaddon's Invuln save, 0.888 wounds after Abaddon's Feel No Pain save.

Horus (The Talon, after causing one wound with The Talon): 6 attacks, hitting 4 times, causing 3.555 wounds, 1.777 going through Abaddon's Invuln save, 1.184 wounds after Abaddon's Feel No Pain save.

• So for the match:
  • Round 1: Abaddon strikes first and causes 2.309 wounds, Horus retaliates with The Talon causing 0.888 wounds, because even though he can do more damage with Worldbreaker dropping Abaddon's Weapon Skill is more important (though that won't happen yet).
  • Round 2: Abbadon strikes first and causes 1.206 wounds (for a total of 3.515 wounds), Horus retaliates with The Talon (1 attack) and Worldbreaker (5 attacks), causing 0.148 wounds with The Talon (for a total of 1.036 wounds) and causing 0.833 wounds with Worldbreaker (for a total of 1.869 wounds). Abaddon's Weapon Skill has now dropped by 1 and from this point forward Horus gains no benefit from The Talon.
  • Round 3: Abaddon strikes first and causes 1.539 wounds (for a total of 5.054 wounds), Horus retaliates with Worldbreaker for 1.25 wounds (for a total of 3.119 wounds), Abaddon is now concussed.
  • Round 4: Abaddon and Horus hit each other at the same time, Abaddon causing 1.206 wounds (for a total of 6.26 wounds), Horus causing 1.25 wounds (for a total of 4.369 wounds).
    • Outcome: Abaddon wins in 4 rounds of combat, though just barely and on his last wound. Attacking first with The Talon then switching weapons is the most efficient way for Horus to cause wounds on Abaddon but in the end it does not help him win the fight.

• The demon weapon rule is the real MVP here, contributing no less than 14 attacks across 4 rounds of combat, about a third of Abaddon's damage. If Horus had nine attacks he'd do a lot more damage too but for the time being he doesn't.
• Of note is that basically none of Horus' combat tricks work here. The Talon is only useful in reducing stats once and as a result Worldbreaker's concussive rule won't help much either. Against other opponents Horus could make scary plays like concussing an enemy then striking first with his talon next turn to strip of several points of WS and S, or vice versa. These approaches would normally help him slow his opponents damage and give him a major edge but here it's mostly irrelevant
• Do note that this does make a fully powered up Abaddon a more effective melee beatstick than the most powerful of the Primarchs- although in this regard he is similar to Angron, in that he doesn't really give his men any advantages other than the truly ridiculous pile of corpses behind him

Bodyguards vs Bodyguards time

Abaddon has the Bringers of Despair:

WS5 BS5 S4 T4 W1 I4 A2 Ld10. 2+ Armour, 4+ Invulnerable (with MoT) Equipped with Combi Weapon and Chainfist They have Fearless (with Icon of Vengeance), Hatred (Space Marines). Traitor Legions supplement grants Abs one Look Out, Sir! re-roll if he is joined to Bringers of Despair.

Horus has the Justaerin:

WS5 BS4 S4 T4 W2 I4 A2 Ld9 2+ Armour, 4+ Invulnerable Equipped with Combi Weapon and Chainfist Stubborn, Furious Charge, Slow and Purposeful.

Both attack at the same time. Both hit on 4+, both wound on 2+, giving an average of one wound each, which is saved on a 4+. By round two they will kill each other

I am giving this to the Bringers of Despair, as they would last longer with Fearless than with stubborn, can move faster, and cost fewer points. However, the Justaerin can have a multi melta, and become BS5 shooting within 12" range, and if Horus is on the field he boosts them up to BS6 and Ld10.

Conclusion

So, all in all, a fully powered up Abaddon and bodyguards vs Horus + Bodyguards would be a rough win in Abaddon's favour, mind you, If we included the shooting phase with all the various available weapons it could all be very different.

Also of note, a vanilla Abaddon could barely hold his own against Horus, being swatted aside like a fly. Parallel to that, you could almost have two of him points wise (Still a fight Horus would win).

One further note is that this assumes that the rules for Horus represent his Final-Form; Forgeworld have stated that some primarchs will be getting different rules as the Horus Heresy series goes on, we've seen this already for Lorgar (transfigured), Corvus Corax (after Isstvan) and Perturabo (with Hammer). We know from the book series that Horus goes to Molech to get a level-up from the four Chaos Gods which at the very least might be represented by the mark of Chaos Ascendant which Abaddon has, though funnily enough Horus having all four marks wouldn't change the outcome of the fight at all, Khorne and Tzeentch marks would not come into play (nobody is charging and Horus already has a 3+ save), Nurgle does not help against Fleshbane and striking at the same Initiative as Abaddon the entire fight would not help Horus at all. Anyway, when Horus gets back from Moloch it's most likely that fully powered up Abaddon wouldn't stand a chance as this is supposed to make him equal to the Emperor himself; so the likely result is that Abaddon gets demolished in at most two rounds of combat.

In the Fluff

It actually happened. Kind of. That time when Abby assaulted our favorite FABULOUS space Dr. Mengele to stop him from cloning Horus, he was a bit too late. Bile actually made a stable clone of the Warmaster, complete with his armour, the Worldbreaker and a large part of his former incarnation's memory somehow implanted into him. But did Abby bow to his poppa reborn? Fuck no! He took his Talon, and proceeded to kick the ever living shit out the Horus 2.0, which culminated in him breaking the Worldbreaker and subsequently tearing the clone apart.

What a douche.
