Hehe. At first did I think this was nothing but a bad joke, but I now see that it is actually debated in favor of the five opponents to Mewtwo.
Personally can I not see Mewtwo possibly lose against this bunch. I can not even see normal Mewtwo lose, although this is Mewtwo with 24h preparation.
- Mewtwo will design a number of devices. One device will increase his awareness by creating an armor with sensors. This will allow him to even quicker than normal see an incoming enemy or attack. This armor would be based on the same type of technology that the mirage system.
- Mewtwo will create sphere traps and deploy them over the field before the actual battle commences. This will grant him the advantage of defense when he then tricks his opponents to step into this and they will be sealed shut. This is the same type of device that prisoned Mewtwo in 'Mewtwo Returns'
- He will create a device and apply it to first mentioned armor, this containing the spheric protection that a pokemon center uses to regenerate the health of pokemons. This will allow him to take extra beating and regenerate health faster than usual.
- As a final touch will Mewtwo design shock fields. This will he apply to the ground and any walking being, or anyone touching the ground will have a 10.000 volt pulse sent trough their body. Last time I checked, only Xemnas has swift flight of the 5.
Leaving: Mewtwo Vs. Xemnas
Because:
- Xemnas being the most intellectual and will not fall in Mewtwo's traps
- Xemnas if anyone will be able to survive what telekinetical grasps Mewtwo does
- Xemnas will likely be able to break out of the trap that keeps people in place, since he is "nothing"
Assuming this is Xemnas in his prime:
Mewtwo 7.5/10
But
Vs. Sora, Riku, Roxas and Larxene:
Mewtwo 9/10
Vs. All
Mewtwo 6/10
