Editing 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 goint 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.

==Crunch==
Abaddon strikes first, with 5+D6 attacks thanks to Drach'Nyen, giving an average of 8 attacks. These will hit on fours with re-rolls, giving 6 hits. These will wound on twos, with re-rolls, giving 6 wounds on average. 3+ Invuln means 2 wounds
Horus strikes back with Worldbreaker, hitting with 5 attacks on 4+, giving 3 hits. 2+ to wound gives 2 wounds. 4+ Invuln and 5+ Feel No Pain gives 1-0 wounds.
Horus will then regenerate a wound on average. 
Abaddon hits first, with 5+D6 attacks, giving 8 attacks, hitting on 4+, wounding on 2+ with re-rolls, resulting in 2 wounds, Horus then saves one, giving one wound
Horus hits back, same as last time, with Abaddon losing between 0 and one wounds. 
ETC, ETC, ETC. As you can see, they are exceedingly well balanced. However, as Abaddon can stand up to the most powerful of the Primarchs, it should be obvious that he can paste anything in WH40k proper

==Bodyguards vs Bodyguards time==
Abaddon has the Bringers of Despair
WS5 BS5 S4 T4 W1 I4 A2 Ld10. 2+ Armour, 4+ Invulnerable
Equipped with Combi Weapon and Chainfist 
They have fearless, Hatred (Space Marines)

Horus has the Justaerin
WS5 BS4 S4 T4 W1 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. Also, while the Justaerin can have a multi melta, the Bringers of Despair can inflict more damage in the shooting phase with BS5 and Combi weapons. 
That said, if Horus is on the field, the differences become neglegible, as he can boost the Justaerin to BS5 and Ld10

So, all in all, a fully powered up Abaddon and bodyguards vs Horus + Bodyguards would be a rough draw, although if Horus could call down the Orbital Strike, it could steal it. Mind You, If Abaddon charged, it could all be very different.

Thus, in total summary, the result of this fight will come down entirely to the luck of the individuals. One Doesn't even want to think about what would happen if Abaddon's WS and I were reduced to 1.
