Odd Alliance vs the Immortals Rebuttal
I'd like to start by commending you on a good write up. I'll point out my problems and opinions, but all in all, stelular job.
Chunk, being a friend to Wally West would most likely know some of Wally's stories about Dr. Light, from when Wally was a Titan. That leaves Anti-Vision and Prometheus as the wild cards for the fight.
I'd say it's a stretch that Chunk would know any specific foe of Wally's past. Who knows what they've discussed, so we can't assume that Wally's randomly brought up one of them an that Chunk would remember much about him. I think it's safer to assume Dr. Light is also among the unknown.
Prometheus and Dr. Light would both recognize Sodam Yat as a Green Lantern, as they both have had several dealings with the Green Lanterns of Earth. However, it is doubtful that they would know they are dealing with a Daxamite, as Daxamites by general rule are xenophobic and rarely venture outside the confines of their home planet.
I'd assume having the eyes of a Daxamite would be enough to tip them off.
Prometheus strategically attacks what he deems to be the most powerful opponent in the Green Lantern on the team. He utilizes the neural chaff that interferes with a person's thought processes and concentration and smirks as he watches the Lantern struggle to keep a construct up, instructing Anti-Vision to attack what he deems to be a defenseless humanoid with a blast from the crystal on his head. Unfortunately for him, the blast of solar energy did anything but harm the Daxamite, providing him pure fuel to convert to his natural power base. Upset by the fact that his ring does not appear to work against these two assailants, Sodam lets loose a burst of heat vision, searing the synthezoid into two symmetrical, vertical halves. At this point Prometheus realizes his strategies have failed, and his data on this subject was incomplete. Sodam uses his superspeed to grab Prometheus, ripping the circuitry from his helmet before knocking him in the head hard enough to leave the anti-Batman unconscious. With his concentration returned, Sodam makes short work of ensuring that Prometheus will not be seen again this battle, trapping him in a small green facsimile of an Oan Science cell.
The main problem I have with this is that Anti-Vision attacks with a solar blast. This is coincidence because of Anti-Vision's powers, it's the only one that could help Yat. Anti-Vision's first and main line of attack is always the phasing his hand through the head type of thing. He's done this in most of his appearances well before any solar blast, so most likely this is what he will do to stop Yat... and it would defeat him. Especially if they do recognize him as a Daxamite due to his eyes.
Also, you have Sodom Yat kill Anti-Vision (not knowing he's a machine). Green Lanterns don't kill unless they're killing Sinestro Corps members.
Going from what intel Wolverine could give them, Selene decides that she and Validus would be the best suited to take on Onslaught. Selene uses her telepathic powers to mask herself physically from the rest of the enemy team, and temporarily just to set him off his guard, Onslaught, as she makes her appearance that of Wolverine as both her and Validus charge her. The tactic to draw the defensive works, if only for that brief moment before Onslaught realizes truly who is rushing him. Thinking that Selene is the bigger threat of the two, and that he'll be able to dispose of the onrushing brute as soon as he takes care of Selene proves to be his downfall. As he enters a psychic battle with Selene, and is easily beginning to overwhelm her, Validus fires a mental bolt of his own, at the engrossed and dueling Onslaught. The sudden secondary psychic attack knocks him out of concentration with Selene, allowing her the moment she needs before she sucks in Xavier's life force leaving him little more than a lifeless shell of existence.
The biggest problem with this is assuming that Selene's mental illusion could fool Xavier for even a second. His power is far superior to hers, especially with her choosing to pose as someone he knows best... Wolverine. There would be absolutely no fooling Onslaught in this scenerio. And to be honest, no matter whether it's Selene or Wolverine, he can still drain them both just the same to the same conclusion.
I detailed a battle between these three in my own write up to where Onslaught did have problems against Validus while getting Selene's help in secret. Knowing that Selene was there and nearer could potentially be the thing that turns my version of that match into a win for Onslaught. Validus beating on him would only go so far before Onslaught just drains Selene's mental energies, taking her out of the match (it's much easier for him to drain than her, so he'd do it first for certain). And when he can focus on Validus without Selene's aid, he should be able to either A) defeat him, or B) hold him until help arrives.
Wolverine almost immediately takes to the woods to get a better vantage point to attack his foes. Chunk makes himself a target, attempting to draw out Dr. Light in a battle of light versus the void. Light emits a blinding flash of light that disorients Chunk long enough for him to be caught off guard enough for Blink to teleport into existence with her arm in the middle of Chunk's chest and she teleports again this time with his still beating, bloody heart in her hand. At this point, Light and Blink turn their attention towards the other opponents. Immediately after sapping Xavier dry, Selene once again makes herself appear to look like Wolverine to those without enough mental prowess to know otherwise. Meanwhile, Wolverine has been watching Blink's movements, strategising after seeing what she did to Chunk. He notices Selene's masked form as she looks to be backing off.
Any one who knows me knows that ain't how I play. She ain't gonna fool the teleporter for long. Wolverine thinks to himself. Sure enough soon Blink 'ports herself into Validus's brain cage and manually scrambles the pink matter she grabs. Seeing her having taken out two of his teammates, the real Wolverine acts. Dr. Light is too busy concentrating on his teammate's successes in taking down what seemed to be one of his opponent's biggest threats. He doesn't even know Wolverine is behind him until he feels the six adamantium claws pop out of his chest like an Alien.
Aside that I don't see Selene or Validus making it to this point of the battle as detailed above, I actually have nothing against this portion of the match. These types of battles could go any which way, so no problems here.
At this point, Sodam has finished his battle and sees that Selene is in danger as it appears that Blink is now targeting her. "Sorry friend, but a noble sacrifice to achieve one's goals is some times a very unfortunate and sad occasion. He watches as Blink teleports behind Selene, her arm materializing through the Black Queen's neck. However, she too did not know about the power sets of Daxamites as he unleashes a blast of heat vision hot enough effectively kill enough of her brain cells to leave her nothing more than a cucumber the rest of her existence.
Again, I think you're taking Sodam Yat too far in effectively killing Blink. He's a Green Lantern and a hero. They do not kill.
Overall it was a good write up. I think the three biggest problems were:
A) Yat's eagerness to kill twice
B) Selene's illusion wouldn't do squat against Onslaught, changing the whole dynamic of that match and this whole battle.
C) Anti-Vision's using the one power against Yat that would help him, and not the main assault he uses, which would defeat Yat.
However, a lot of the match was similar to my own layout so it really could fall either way depending on minor things, so it should be interesting to see what the voters think.
