What if battles 2

Android 17 and Android 18 vs X and Zero

Toomi: And like his predecessor, X utilizes a variable weapon system, allowing him to obtain abilities and weaponry from defeated Mavericks.

Megumi: With 84 Maverick weapons in total, that's lots of ways to take down his enemies. For projectiles, Shotgun Ice and Crystal Hunter freeze foes, Sonic Slicer fires energy blades that ricochet off walls, Magnet Mine can be controlled and sticks to walls, Circle Blaze fires a flame which explodes, and Thunder Dancer fires a bolt that can strike one foe after another.

Sachi: But X is not the only one fighting, he has his partner and mentor, Zero, who is a creation of Dr. Wily.

Toomi: No matter how many times he tried, Dr. Albert Wily could never defeat his nemesis Mega Man, the prize creation of his rival Dr. Light. So he made robot master with some of Mega Man's capabilities, Bass, but his inability to defeat the Blue Bomber combined with his tendency to disobey Wily led Albert to built a robot that would blow him away. More advanced than anything he had built before, Zero was his greatest masterpiece.

Megumi: Only problem was that he was overly-violent and wouldn't do anything Wily told him to do, so he put Zero in his timeout capsule... then he was woken up a century later by a group of Reploids.

Sachi: Still as uncontrollable as ever, he destroyed them and any and all intruders that entered Wily's old fortress. To put a stop to Zero's Maverick activity, as well as prevent the loss of any more of his comrades, the Maverick Hunter Commander Sigma went in alone.

Megumi: Sigma got beaten up pretty good, but once Zero's crystal thingy started hurting his head, Sigma scored a KO.

Toomi: After he was looked over by Dr. Cain, Zero had recovered, no longer showing any Maverick behavior, and was placed into the Maverick Hunters' 17th elite unit, under the watch of Sigma

Megumi: Boy, that must've been a really awkward relationship. "Hey, remember when you knocked off my arm?"

Sachi: Zero soon reached the rank of A-Class, the highest Maverick Hunter rank at the time. It was then that he met the B-Class hunter X. The two immediately became partners, with Zero almost acting as a mentor to X.

Toomi: Zero's primary weapon was his built-in Zero Buster.

Megumi: You could think of it as a next-gen Bass Buster, and what it lacks in a rapid fire setting, it more than makes up for with its power. But the Z-Buster would become his side arm after he came across this beaut: the lightsaber.

Sachi: The Z-Saber.

Megumi: While this beam sword switches between being a fluid and solid shape, the Z-Saber is absolutely devastating on contact, cutting down Mavericks in a few swings, if not just one. It can also destroy enemy projectiles, or, LIKE a lightsaber, deflect them, sometimes back at the bot who fired at him in the first place.

Toomi: And he enhances the Z-Saber even further with his Learning System, imbuing the weapon with various properties.

Megumi: See, he doesn't really take enemy weapons, but rather properties to create his very own techniques. His most well-known being Ryuenjin, a rising slash that imbues the saber's blade with fire. Alternatively, he can just stand and create an upward wall of fire with Shoenzan.

Sachi: He can also imbue the Z-saber with lightning, creating a downward bolt while moving or even enveloping him in an electric tornado. He also thrust with the electrical Raijingeki.
