Perturabo in the Metal Gearverse

Perturabo (Warhammer 40,000) enters the Metal Gearverse

Assume all characters are in play because, why not

Standard one guy invades to wreck shit deal

What happens? :maybe

Who is writing him?

If he is being written by Aaron Dembski-Bowden Armstrong might solo.

If he is being written by Graham McNeill he probably solos.

Edit: Wait, is this Daemon Perturabo?

Any Primarch in any form > Metal Gears

I thought Pre-Daemon Perturabo would be a better idea, didn't Daemon Perturabo corrupt a Forgeworld conquering it by doing so or whatever?

Yeah, he corrupted an entire Forgeworld with sorcery.

Pre-daemon Perturabo still wins in most cases. Even accounting for low Primarch feats.
