Does this take place outside of the Matrix? If it does then Morhpeus would be pretty useless.
Is it Jet Li's character at the end of the movie or beginning? Because that character got stronger with every version (from another Universe)of himself he killed. IIRC in the very last fight i think they were moving close to light speeds, but Im probably wrong about that.
Lets start with those who simply have no real shot at winning this. IMO these guys are all bad asses, but just don't make the cut against the others:
1. Robocop
2. Punisher
3. Riddick (Im debating whether he could make the second cut)
4. Morpheus (outside the Matrix)
5. The One (at beginnning of movie)
6. Cyborg Jason (He might not die, but he would definately get blown up, dismembered, or vaporized)
Then there was 9:
Captain America and Daredevil would be real contenders if they were given better offensive weapons. They just cant deal enough damage with their standard gear to finish this battle off.
Alice does have some pretty nasty TP/TK, and above average fighting skills. However, I believe she is left vulnerable once she has used her mental abilities.
And then there was 6:
T-100, Batman, Gambit, and Blade are going to be contenders, but IMO would fall short against the last two standing at the end of this gruesome war.
In the end i believe two will be left due to their superior combination of strength, speed, agility, durability, fighting skill, fire power/offensive weaponary, and intelligence/ experience. As you probably have figured out by now, they are Slade and Elder Pred.
I will not attempt to figure out who would win between these two cuz honestly i have no clue.
Note: This contest was much harder to decide on then the previous survival of the fittest. As always the results of this battle are subject some level of CIS/PIS which could alter the outcome of my decision. If these induced stupidities are taken into account their really is no contest and Batman kills/Batkicks everyone.
