The Covenant (Halo) vs The Grand Imperium of Man (Warhammer 40k)

[ChaosLord29]

Oh and it does nothing to prevent a counter attack from the Imperium.

It would only help them in terms of retreat, and it's worth noting that Covenant ships are more or less in a state of unpreparedness once they've finished a slipspace jump. Imperial Ships are disoriented, but can finish a Warp Jump at full battle stations, guns loaded and shields up.

Then there's High Carity itself, which does not boast a comparable FTL and sublight speed maneuverability. Assuming the Imperials manage to follow a Covenant ship back to it at any point, I'd say we're looking at the Terminator Company teleporting into the High Council scenario outlined earlier.

Obviously not right into a meeting or anything, but the point is, less than all the Prophets are likely to survive the experience.
