Megaman X4 - Final Boss - Sigma (No Damage)

Hardest boss in the game (well, he is the final one after all). His third form is very hard to defeat without getting a single hit because of one of its attacks.

[@noahsteele6717]

This comment is incredibly old, but I just played this game today, so here’s a tip: stand so that you’ll be in between the red and blue heads. Use a plasma shot to destroy the red head on the right while sigma sucks up the debris. Then, once the head is destroyed, wall jump into the corner of the room and stay there until the attack ends. Be sure to leave immediately after the attack ends, though - you don’t want to get squished by the heads spawning in.

I enjoy X's character, how he holds himself accountable and isn't afraid to confront the possibiity of him becoming what he fears/hates/fights against the most: A Maverick. A weapon. A threat to life. X is humble, becoming so powerful only because he see's himself as having so far left to go. He strives.....not for power, but to become b e t t e r. To be become more skilled. To rely on himself and the strenth of those he's forged bonds with, instead of raw power. Having witnessed first hand, what raw power does to others. What it can do to HIM.

[@GarryDumblowski]

If I may ask, is there a specific moment you're thinking of when you talk about what raw power did to X?

X cries like a pussy every time he puts down a psychopathic threat. Fondles the balls of his enemies.

[@DuumKraddle]

I love the character progression from X to X5. X1 shows how he is still isn't reached his fullest potential, X2 shows he get more rensponsible and grow more from previous game, X3 is still the same as X2. Then X4 change quite drastic, from working with zero to all by himself. (Double too but play it for yourself and you see why.) Then finally, X5 shows the teamwork aspect for X, Zero and the rest of the crew in X5 too. given that X5 was suppose to end the story there, it gave you a insight that both would rather sacrifice and help each other out no matter the situation.

[@boi1595]

Invincible Shrimp lmfao

[@dreamhollow]

The third phase always made me feel really weird. Like Sigma goes from a relatively normal looking Reploid and then he's just a giant head shooting wind and garbage at you.

[@The_Natalist]

Thats because he's a virus (its supposed to make you feel uncomfortable)

[@nt-fo9pt]

I think the idea, which may have been lost in translation (not surprising considering X4's dub), was that after his Grim Reaper form was destroyed Sigma used his viral form to infect the Final Weapon itself. This is why both of the main Sigma bodies in his 3rd form have cable like attachments to the Final Weapon and how Sigma was able to set the Final Weapon to self-destruct despite being busy fighting you.

[@shadowslayer1985]

I think those are attacks from past maverick the wind is similar so storm eagle x1 and the trash similar to morph moth from x2, the laser looks similar that the one you get from cyber peacock

Oh god, that third form... Let me get this straight. X popped in on Sigma in the middle of a new body-building session, where he had a big, gun-wielding reploid without legs and the half-finished head of his new giant form? It's so weird!

[@fabrypetty1689]

Look it's been two years since this comment, iand i still haven't found a better use for 'body building' than in this one masterpiece over here.

[@_Venvel]

A few of Sigma's bodies are unfinished when X/Zero/Axl drop in on him. That's why several of them are stationary during the final battle. It makes sense for the Maverick Hunters to try and bust him before he can complete presumed WMDs. The player characters are special ops sent to take him down before he causes further damage.

[@freddywilliams9837]

Definitely true, but I think 4 and 6 are the ones where it's clear Sigma's had the least time to prepare. I mean, what are those three sigma totem heads? My only explanation is that Sigma was super unfinished at that time, but even that's a bit vague given how two forms don't seem to match anything else he's done.

I love how this fight isn't really *that* difficult when you get down to it, but that's the point the fight's difficulty doesn't come from actual difficulty (most of the time), but from yourself all the different sigma heads, compared with his final form and battle music are designed to overwhelm you, the player so you'll slip up more and have sigma win it's a neat concept and execution, which probably makes it one of my favorite final sigma fights.

[@justjazznow5817]

I used a sub tank on phase 2 n this guy beat him no damage no upgrades and just with lemons..... LEGEND

[@ArcadeStriker]

Here is some explantation and strategies (using X, I still have to beat him with Zero): First of all, I would recommend having at least 1 or 2 subtanks (What you can find, and whatever you think should be enough for you), and having the X-Buster and Leg upgrade (You can get the helmet one if you want). -The first form is easy peasy, as you can do as you see above in the video, or if you got the X-Buster upgrade, hit him a the charged Rising Fire, and then it should have lost most of his health and finish him off. -The second form can be less of a threat with a simple pattern: After he throws his scythe the first time, the 2nd time he will throw it at you, and you should be hanging/walljumping in the wall and IMMEDIATELY drop off when he throws it to the wall (Delay some little and it will hit you), and then go to the wall above him and shoot him (kinda like the video). Rinse and repeat this, as the scythe pattern keeps repeating, and as long as you keep making the scythe hit the wall, you shouldn't have a lot of problem. -The third form: If you have the X-Buster upgrade, it will help loads. When the three heads appear without a large robot on the right/Sigma giant head on the left appearing, you should have charged the X-Buster and use it against the head that is attacking you. The yellow one can be a little more difficult with the thunders and that it's in the upper center, the red one will come from the right and shoot fireballs, and the blue one (easier one) will come from the right with a ice breath. When the large robot appears, try to see quickly what attack it will use, or rather pay attention to the colored heads position, if they form a wall, then hang in the wall, as the robot will use a attack that will always hit the ground (and you if you are in it), and if it forms kind of a ladder, then it will shoot lasers, try making it shoot down and use those chances to attack him. When the Sigma head appears, you should always keep in the right side (but not too close, there is a possibility that you could end dead in spikes) and when you notice that the heads are in the floor, use the charged buster to get rid of the heads that get in your way to hit the Sigma head, and it will be easier to not get hurt if you have the buster upgrade (the plasma balls will protect you from the debris Sigma will throw). If the heads are in the upper part, keep charging the buster and shooting it as soon as it's charged as fast as you can, along with dashing and dashing to avoid getting pushed to spikes. That is roughly what I can tell from my fight with him (which I just could beat :D), but probably there is something of that general idea in the video too (He gets through it UNHARMED).

[@deandre200318]

excellent job

[@BhChicagoTVStationhistoriesand]

My best advise for this final Sigma battle is one, do your best to get as many of the heart tanks as possible since those greatly expand your life gauge! Ideally you’ll want ALL of them but if you’re one short you can make it work with at least one Energy Tank. Two, get at least one of the two Energy Tanks, even with just one you’ll have a lot more breathing room in case you take a bit of unexpected damage! It’ll just make the final fight a lot more doable. Finally, make SURE you get the Buster upgrade that gives you the proton burst! A powered up buster shot with a proton burst timed right will do a LOT of extra damage and should help you get by! I know this advice might seem obvious to some but I hope it helps at least one person!

Then quickly dash on the right most / left most where he cannot hit you (It depends if he warps on the left or right but you'll get this strategy) 4. Repeat until his cloak burns Works everytime for speedrunning. I advise you stay in the middle so there is a quick time for you to avoid his scythe
