Gotta say, the point of view there seems to be kind of belittling what Samus has done... I'd guess you're not really meaning to, but what your saying is like saying "All megaman has done is kill a few robots", which is true, but you still need to look at things in perspective. Keep in mind that this is all based on my perceptions of each game, without really getting too into either series lol. Master Chief is definitely a conquering badass, I don't know a ton of the lore or anything, (was never all that into Halo) but you don't blast through armies of enemies if you're a mediocre front line soldier. But you can say similar things about Samus as well. The only games I've played any of for hers are really just a couple of the side scrollers, but she may be a mercenary, but she's a space merc, with the skills, tools, and genes, to be one of the best bounty hunters in however many galaxies are involved I'm the metro is games. She may not have the formal training of the chief, but I'd say they're pretty close in terms of experience, and that Samus' survival skills are even slightly superior, making them pretty even all around in the terms of a 1v1 fight. When it comes to physique, I'd give the edge to the super soldier in terms of power, and flat out running speed. I'm not sure if the chozo(?) DNA enhances her physical ability, but I'm going to assume that it does... Because to me, that just makes sense lol. But not enough to overpower the chief given her thin, voluptuous ;) frame. The power suits seem to cancel each other out for the most part as well, chiefs seeming to be focused more on power and defense, while Samus seems to be more all-around, possibly even defensively, but more likely focused on mobility/flexibility with the super ball(?) ability, and looking to be a little less restrictive than the bulkier power armor. In terms of firepower I agree that Samus would most likely come out ahead, since I don't remember any ammo restrictions on hers, or know if the chief had anything that didn't run out of ammo/energy. There's also the fact that in a more realistic fight, Samus would be able to make use of any weapon she might cause the chief to drop, while hers are part of the suit. Both have decent cc weapons which could mean an instant win for either side, Samus with her mines combined with her electro whip thing lol, could halt master chief, and possibly short out his suit, but most definitely wrap him up and injure him pretty badly. MC, with the various grenades at his disposal, he might surprise her pretty well too lol. [Edit]: was brought to my attention that the charge pistol(?) is a covenant weapon, so I've taken it out of the equation. CQ I'd put the edge towards Samus with the superball(?) and electro whip(?), as opposed to the chief and his fists/sword/hammer. With the hammer being his best bet, if he can avoid Samus interrupting his swings. (Smashing the ground would create some distance, but the ball would mitigate the damage. Long range, I'd still say Samus, due to high mobility, her changing shape, and the likely event of the circular motion of the ball form causing most shots to be glancing blows. Combined with the limitless(possibly) ammunition, and tracking rockets to keep the pressure up. Until the ammo started running out, it'd be pretty even, a really drawn out situation. [people may bring up the needler here for tracking weaponry, but I'm going under the 1v1 idea, where it's the chief and his weaponry, not covenant gear or whatever the needler is] Mid range is where I'd say the fight would be most even, each side switching to the most appropriate piece of equipment for the situation on the fly. With his experience MC would probably do his best to keep the fight here, pressuring Samus into backing off, closing in if she backs off to far, waiting for or trying to create an opening. Samus would know she has an edge in some areas, so she'd be trying to get into CQ or back off lol. Like I said, I think it'd be a really even fight, but with two skilled fighters, it comes down to luck or supplies... And my money would go on Samus. [Edit]: without the possibility of being able to shut down Samus' suit with the charge pistol(?), I'd have to say it's even more likely that Samus would be the victor. But win or lose I'd enjoy the show lol
