Samus breaks time with her Speed Boost, similar to the clock-up system in Kamen Rider Kabuto. And honestly, she doesn’t really have to run that far to gain the speed necessary to Boost, and in Morph Ball mode, that boost can be on command.

Blades, snakes, bubbles, fire, oil…?

How many times has Samus been beaten to a near bloody pulp at Ridley’s hands, and still manage to blast his ass into next week? If her Chozo armor can withstand Ridely’s talons and a Metroid’s fangs, Rock’s blades and snakes aren’t gonna do too much of anything. Bubbles won’t work as her suit is calibrated for various gravity and environmental extremes, as well as sudden changes to those extremes. The Varia Suit was designed to handle extremely high temperatures. And oil? Plasma Beam.

Crash bombs, however, may well be Rock’s trump card. But even still, he must use his weapons one at a time, more or less, cycling through them, while Samus’s arms cycling is near instantaneous – no, simultaneous (she’s armed with tech from Metroid/Zero Mission, in which beam weapon/missile characteristics are stacked).

Sorry, but Rockman and Rush just can’t win this fight without being able to match Samus’s defenses. They are both too vulnerable. I would also imagine that Rock may potentially have trouble keeping his systems in order, as Samus’s Wave and Charge Beams have traditionally caused electronic interference and EMP like effects that alone are enough to cause robots to short and malfunction.

Think of all of the powers he’s obtained over the years, compared to what Samus has.

Yeah, at this point, Rockman has enough abilities in his mega buster to be able to handle anything and everything Samus throws at him.

If you guys wanna consider all of that mobility and what not into it, have at it… but I mean, damn. Rockman can stop time. He can hurl saw blades, snakes, bubbles, fire, and chuck crash bombs.

That bitch doesn’t stand a chance. XD

Turf – Even
At this point in the Metroid timeline, Samus is making her first foray into the depths of SR-388. She may have a basic rundown of the planet’s surface downloaded to her suit via the Federation, but this battle is likely to end up anywhere. Unless her suit has access Chozo archives (the manga reveals that the Chozo were active on SR-388 while they were raising Samus on their homeworld), she’s just as lost as Rock most definitely is.

Weapons – Samus
Thanks to the wonders of the Deus Ex Machina device Rock is bollin hard. His arsenal of elemental weaponry is sure to give Samus problems. The problem Rock has here is simple: his ammo is limited and he ain’t fighting robots that conveniently drop rounds when they blow up.

Samus, on the other hand, is out gunning Rock thanks to the DEMD. Equipped with every weapon upgrade she’s encountered up to this point means she has the power of light and darkness, electricity, plasma, ice, and various degrees of concussive force at her disposal. Rock may have the tech to counter, but her can only do for so long before the shear overwhelming power Samus’s arm is packing finally takes its toll. With advanced multilevel targeting systems, Rock’s going to find it hard to stay mobile and unscaithed, while Samus will be able to keep her distance with confuse poor Rock with tech like the Speed Boost, Space Jump, Morph Ball, and Screw Attack. Oh, and Rock’s shield weaponry? Samus can just rip that mess away with her Grapple Beam.

Defense – Samus
Let’s face it, Rock takes damage. Those spikes and crazy jumps do a number on a robot’s plating. He’s fast and precise, but Samus can be faster and more accurate, even without her suit (she’s part Chozo afterall). Add to that the hefty defenses her suit has been upgraded with via the DEMD: Varia (heat), Gravity (speed), Dark/Light, Phazon, PED (phazon reserves). Basically, Samus can withstand just about anything Rock could possibly throw at her. He PED suit will allow her to use Hyper Beam in conjunction with the Phazon suit upgrade: instant KO for Rock, assuming there’s anything left of him if it connects.

Mobility – Samus
Speed Boost, Space Jump, Morph Ball, Screw Attack, and Grapple Beam. Rush wouldn’t be able to keep up…

Overall Power – Samus
Without her suit, Samus is a bio enhanced super soldier, basically. Increased strength, speed, agility… Not inhuman, but not excessively superhuman. In the suit, Samus is a wrecking ball when she wants to be. Her being a lady often leads to more finesse work as she tends to lose herself when she goes all-out (see manga/Dark Samus is an manifestation of her dark nature). Her weapon payload is good for one thing: blowing stuff up. Her Gunship is one of the fastest in the Federation and packs as much punch as her arm cannon.

Rock really isn’t much without defeating a few Robot Masters first. And he must defeat the Master to get the upgrade, so he won’t be stealing much tech from Samus.

I think its clear who the winner is here: Samus, no question.

Rock will certainly put up a fight, and it will be one hell of a brawl, assuming Metroids don’t interfere – in which case, this match would technically end in a draw as the two will likely team up to, well, survive. Rock’s own Beam weapons will keep Samus at bay for a time, forcing her to stay back and on the move. Ultimately, her suit will find the opening she needs (if she doesn’t figure it out for herself witch is just as likely), and she pick Mega Man apart.

Period.
