Marvel said:Powers
As a member of the Technarchy, Warlock is a techno-organic being, without true form but constantly changing shape. He can also approximate any organic form as well-- appearing human when necessary. Warlock's physiology is also able to survive within the vacuum of space. When "feeding," he injects a techno-organic virus into an object, converting it into a techno-organic form like himself, and absorbing its energy into himself. Alternatively, he can absorb pure energy, like electricity from an outlet. Warlock was once identified as a mutant, as his "mutation" was his passivity that was uncharacteristic of the war-like tendencies of the rest of his race. Currently infused with nanotechnology, Warlock can repair his body as it is damaged. The technology allows his body to "upgrade," adapting to any given situation similar to the Sentinels' ability to adapt on the fly to a variety of mutant powers.
Weapons
Nanotechnology has enhanced Warlock's shape-shifting abilities to allow him to mimic not only forms but also weapons such as energy projectiles, force fields, and more advanced versions of the abilities that he had before Bastion infected him with nanotechnology.
Astra:
*Astra can alter her body's molecular density, allowing physical attacks to pass through her without harm and allowing her to pass through other objects or people without harm. By slightly solidifying herself inside another person, Astra can render them unconscious. While intangible, she can physically impact other intangible beings.
*Astra has used a Shi'ar anti-gravity device to fly.

Interesting match-up. I always think of Warlock as Marvel's version of Michael Jackson..."he's a lover, not a fighter." Sure, he'll fight when he absolutely needs to, but it's not in his nature to severely hurt someone. If Astra was taking on his father, she'd be in much bigger danger.
While neither will know of the location, the fact is that Astra will know of the Phalanx. It was the Phalanx that nearly destroyed the Shi'ar, and she will perceive Warlock as an immediate threat. If anyone knows how to now defeat the Phalanx, it's the Shi'ar.
What also benefits Astra is that Warlock is a Technarchy, and does not try and assimillate his opponents. They are individualistic, unlike many other of the Phalanx.
Rebuttal: Astra vs. Warlock-Phalanx
There is not much I can say here because simply you say nothing. All I read from the above is that he will not kill her but where do you remotely mention how she defeats him because I cannot see it.
He is far superiour to her and he knows he has to defeat the one individual he will find. He is not just going to lay down. This is round 2 and therefore he knows he has defeated Juggernaut. Here he has to defeat Astra and he will do so with relative ease especially because she has no way to defeat him.
Winner = Warlock
There is much that shows he will be in no way "far superior to her." As pointed out, Astra will know her opponent, as the Shi'ar is very, very familiar with the Phalanx. They just had a humongous battle with them during Annihilation; and, as Astra is a current member of the Shi'ar Imperial Guard (and, a founding member and former leader), she's got access to all that information. (After all, the Shi'ar has learned how to defeat the Phalanx, as Deathbird did.) Astra will know what works and what doesn't.
marvel said:They infiltrated the Shi'ar Empire as the "Pure", killing tens of thousands before the X-Men fought them on the Shi'ar throneworld and separated the transmode virus from its hosts, killing most of those Phalanx.
On the other hand, Warlock won't know jack about Astra. Also, Warlock was not like his father. Thirdly, using normal Phalanx techniques don't translate to Warlock, because he is not one who would assimiliate another character.
One big problem with the above rebuttal that needs to be pointed out is "This is round 2 and therefore he knows he has defeated Juggernaut." As JH pointed out to me during Season 1, characters have no knowledge of previous battles in this contest. Thus, Warlock has no idea he beat Juggernaut. (Thinking about it, it's a very wise decision by JH, because another person might have knowledge that wasn't brought up in a debate, and just because we get a win in one round, doesn't mean the same can be done if another person debates the opponent.) The only time we retain memory of previous battles is when there is a rematch.
Her powers are simply to become intangible. She is not a great warrior of the Shi'ar and as many know they get defeated all the time. And excuse me but the Shi'ar did not defeat the Phalanx.
So really what you suggest is plainly wrong given Astra does not have the resources of the X-Men especially not their powers.
Warlock has had contact with teh SHi'ar before and recently he has been in space fighting alongside Nova so I would suggest he may know something about Astra after all. Not to mention that he can access during his 24 hours of prep time databases (X-Men, Phalanx, etc.) which surely have information of someone who is a member of the Shi'ar Imperial Guard.
