Mercury Vs Deadgirl
Okay, so this is a tough match... but I think that Mercury has a chance here. Okay, so here's the idea...
First off... Mercury would know everything about Deadgirl. Why? Because she was a freakin X-Statix member, and they were huge television celebrities. Do we know anything about Tom Cruise and Brad Pitt? We know everything about Tom Cruise and Brad Pitt... thus, the same holds here. Does Deadgirl know about Mercury? Nope. Now I know what one or two of you are thinking... she can talk to the recently dead. Thus, she can talk to all the students who have died recently to learn everything about her... but no, that's not the case. Reason being... the Childhood's End/Nimrod storyline has been going on for a year, and while we started this tourney, meaning that story doesn't count. That means we're basically taking Mercury from her last appearance in the Hellions mini... and by that time we knew of no close allies or friends who had died. Thus, Deadgirl has no info on Mercury.
Now that being said, I don't think she needs any. She's a liquid metal girl named Mercury. You can get an idea of what she can do.
Okay, so now that that's said, here comes the hard part. Why would Mercury beat Deadgirl? Okay... here I go.
First off... Mercury does not need to maintain her human form and can basically do anything that the Terminator dude can (as stated by the creators). She has been shown in the comics to be severed and she reforms without problem. She can adheave to walls, cielings, hide easily, etc. She can take pretty much any physical beating. The only main weakness that she has is electricity, and Deadgirl has no expertise in that. One could say that they are in a school, and that a means to create electricity could be found... but Deadgirl's never been shown as intelligent beyond that of an average girl. She'd be about as good at finding or conducting electricity as anyone else... which means it won't be found. Not only that, but Mercury also knows that her weakness is Electricity, and being familiar with schools, will know where to find it, how to keep away from it, etc. It'd be hard for Deadgirl to tag her with electricity.
Okay, now that Mercury is covered, let's talk about Deadgirl. The girl is tough as nails. She can talk to the dead and can come back to life once dead. She can lose body parts and can reattach them, or eventually regrow them. She can create claws and can phase her body like that of a ghost. She also has above average strength and agility... though it isn't spidey-like or anything... just above average.
Okay, so it sounds like it'd be hard for Mercury to physically beat Deadgirl too.. right? Wrong! Here's why. Though Deadgirl can come back to life after death... she does have to be dead first... and even if she is dead for a moment... that moment is all that's needed to declare victory. She was incompasitated... she loses. Okay... that said, she can also rejuvinate her body when wounded... thus, can't be physically wounded, right? Wrong! A foot from space hit her in the head and she was killed of a physical wound for a little while... she was out by a physical assault. And in the lamest death and poorest writing possible... yet, still canon and effective in this tournament... Deadgirl met her untimely demise by being hit by conventinal military means (bullets, missiles, etc.). I don't specify that because she was killed off screen if memory serves me, and we don't know specifically what they used, but they were just basic military soliders, so it wasn't anything spectacular. That being said... a physical assault would wound and kill Deadgirl. Now her other powers... talking to the dead, won't do much in this match... moving on. Reanimating recently dead... again, nothing for this match.. moving on. Turning hands to claws... can be used, but won't do squat against Mercury... moving on. And lastly... she can phase like a ghost... something she can finally use... and the thing that will be hardest for Mercury to overcome.
Okay, so now that we see where the characters are powerwise compared to one another... here's how the match will go. Both will be in the school searching one another out. Mercury will probably be telling other students to get out as she finds them to keep them safe. Deadgirl won't be as compassionate, but she's also not one to put innocent people in danger, so she'll let them go. Mercury will probably be a little intimidated by facing a true to life X-Static, that she'll be extra nervous and cautious. She will hide and travel in small hiden forms, such as a small line of metal along the crevis between the floor and wall, or the wall and cieling. She will travel on the bottom of steps, or on the side of elevators, what have you. Plus, it won't be hard to find Deadgirl... as there will be either screams of her appearance... or nerdy fans rushing for her autograph. Needless to say, I think it's safe to assume that Mercury will get the drop on Deadgirl.
I won't go into a long boring battle... so I'll just cut to the chase. In the battle, Mercury will claim victory by initiating a physical assault. Her nerves will be shot by facing a professional, and she will go all out on her foe. She will form her arms and form into knives (as she commonly does) and other such battle arsenal, and she will just tear Deadgirl to pieces. She will launch the attack and take a chunk out of Deadgirl's head, and run down her while jutting razors through her and cutting her to pieces. A quick assault. Mercury will know of Deadgirl's floating, phasing, ghost abilities, and will know that a quick assault is needed, and a quick death. Don't give her the chance to go ghost (to quote danny phantom) Deadgirl can heal from this and can return from the dead... but until she does, she is out... and Mercury is victorious.
Okay, now I know some of you are thinking "that's kinda viscious for Mercury, and out of character, as she's a sweat girl." This is correct, however you have to think of it this way. Deadgirl is a television celebrity. Mercury knows her real well, and simple school library searches during preptime can get Mercury all the info on Deadgirl that she wants. She will know of Deadgirl's abilities, and will assume that she will be able to heal from this and return alive. She knows that her assault is rough, but not lethal, and that all will be well in a matter of minutes, thus, she would have no problem with the assault. And let's not forget, she was trained by Emma Frost. She has it in her. And if this assault does somehow kill Deadgirl... how was Mercury to know it would? She's survived such things before... she wouldn't have known better... not out of character at all.
In the end... Mercury totally wins this match without a problem.
Winner - Mercury
