Megaman X4 final boss guide (SPOILER ALERT)

Here goes, the final boss of Megaman X4, Sigma. Previously in the game, after defeating general, you would have thought its the end. However, the destruction is still going on, that would mean someone is still controlling the entire situation even with general defeated. That person is none other than Sigma, the once leader of the maverick hunters. Sigma betrayed the maverick hunters, with the only goal to exterminate humankind, and YOU have to battle against him to end everything.

After defeating general, you will be teleported to a space satellite. You will first have to battle the 8 maverick leaders again before fighting sigma. These 8 maverick leaders should not be a problem to you, as you would now have all skills learnt and with increased vitality bar. Then lets cut the useless talk and move straight to the battle with sigma.


There will be 3 forms of Sigma, and you would have to fight all 3 of them in a row. First goes, his first form, the reaper. Looks strong though, but actually he is even easier to kill than battling the maverick leaders. He has a very obvious attack pattern, so dont missed it. Weakness = Fire

For zero,
When starting the battle, dont move around, just stay at that postion. Sigma will just disappear. For about 1-2 seconds, he will reappear right above you. Seeing him above you, immediately do a ryuenjin. He will be on fire and then disappear again. He will reappear right above you for a 2nd time, and you just have to ryuenjin him again. Once you had ryuenjin him twice, quickly jump and clinch to the nearest wall, as high as possbile. Sigma would appear at the 1 far end, and then do a reaper swipe across the whole screen. However, as you clinch as high as possbile, seeing him approaching, just jump over him, and then go back to the usual position. So his attack pattern goes, appearing above you twice and then do a reaper swipe and then repeat this pattern. All you have to do is ryuenjin him twice and then jump over his reaper swipe and then repeat this steps. His 1st form will be defeated easily.

1. Dont hesistate to ryuenjin him. If you hesistate, you might get hit by his lightling balls he is about to release. So just be fast and attack him before he does.

For X,
It is the same thing, just that now you are using rising fire. Battle starts, stay at that position. Knowing his attack pattern, rising fire him twice then clinch on the nearest wall. Jump over his reaper swipe. Repeat this steps, his 1st form will be defeated without you even reducing any hp.

Next up, Sigma's 2nd form. An evolved version compared to when he was still the leader of the maverick hunters. He can be a pain in the ass if you just rush to him and keep slashing without thinking. His skills are hurting, and some of his skills might seem unblockable at the start and obviously stronger than his 1st form.  But once you get used to his fighting style, it should be ok. Weakness = None

For zero,
Can be a very tough fight if you are just gonna take him head on without thinking how his attacks really works. I would say a few tries is needed to understand his attacks in order to evade it and use it to your advantage. Even though he is in his 2nd form, he has his attack patterns. As the battle starts, he will jump to the center of the screen and swing his spear 1 round around himself. This is your chance, attack 1 time when he is in the air, then wait for him to swing his spear. Try to stay close below him, but not directly under him. As he throws his spear for a round, seeing it approaching you, do a double jump to dodge it. Make sure your double jump enables you dodge the spinning spear and at the same time do a air slash at sigma, who is still hanging in the air until he gets back his spear. Keep attacking if possible until he gets back his spear. Once he gets back his spear and land on ground, be prepared.

1. His 2nd skill, which i would say is a very annoying skill, where he will throw his spear at your direction. Whenever the spear landed, that whole platform will be on sparks. He would then do a skill to take you out, regardless you are on wall/ground. An absolute attack i would say, can be hard to dodge, but still its possible. After he landed from his spear spinning skill, he will jump again to do his 2nd skill. Be alert, estimate the timing that he will throw his spear and jump before that (Dont do a double jump). He will throw his spear at you, however he will miss as his spear will just go pass above you as you drop back down from your jump. In order to make this go well, i would recommend a few tries to get used to it. His spear would miss you and will strike the wall instead, that wall will be sparked. Attack sigma as he misses. He will then jump to the other corner and do a eye-laser on the whole ground. Before he does that, quickly jump-dash/dash-jump to the wall behind him and clinch to the wall. That would avoid his so-called absolute attack. His attack pattern starts with spear-spinning skill and then his 2nd skill. Afterwards, its back to his spear-spinning skill again. So he is just like repeating his 2 skills in order, over and over again. There are openings during the execution of his skills, so its best to dodge and at the same time attack. It will take some time to adapt to it, so do not worry. Sigma 2nd form can be easily defeated once you grasp his fighting style and retaliate accordingly.
2. One more thing about his 2nd skill. Dont ever let him throw the spear when you are standing on ground. The spear will strike the ground, causing the whole platform to be sparked. You would have no choice but clinched on to the nearest wall. Sigma would then summon 4 boomerangs and direct it at you one after another. I would say it is unblockable, as no matter how i jump, i will always get hit at least once. Maybe if you lucky, you can out-jump it. However, the probability of being that lucky is very low. So i would suggest you always lure him to throw spear towards the wall, so as to escape his 'absolute' attack and even land a hit on sigma.

For X,
Since i have explained his attack patterns above, using X is simply the same. I would advise switching to buster mode immediately when the battle with sigma form 2 starts. Dodge accordingly to his attacks, be constantly charging and shooting when you see openings. Play safe and dont be greedy for hits. Its ok to take a while longer to kill him rather than eating damage just b/c you are too hasty.
Theres another way to fight against sigma form 2. That would be using the web spider skill. It does damaged sigma, but not to the extend of stunning him. So its your choice, this may be more convenient as you do not need to be constanly charging.

The finale, Sigma's true form. Indeed, he is the strongest boss in the entire game. Unpredicted moves with painful skills. He can just summon midgets from nowhere which could deal serious damage if hit. He has no obvious attack pattern, fighting him i would say requires your skill with the controls and how fast you think (whether to play offensive/defensive) when you see openings. I died a couple of times in order to finally kill him. So i would say he is indeed a worthy challenge. There will be a medium hp recovery tank for you to recover your hp lost in the previous 2 fights, so there is not too much worry that his final form is going to take advantage of you. Its a somehow fair fight. Weakness = None

For zero,
It can be very challenging if you play offensive, but very satisfying if you triumph. It can also be kinda relaxing if you play safe throughout. Lets start with being offensive then. At the start of the battle, sigma will disappear and midgets will start appearing (ice/fire/thunder). They can deal serious damage if you fail to dodge it. However no worries, they can be very easy to rid off. These midgets are weak against ryuenjin, so just do it once you see them, dont let them had the chance to execute their moves first. You need to be fast in order to do that. Once these midgets disappeared/destroyed, sigma large face will appear at the most left bottom of the screen. Beware, his face have 2 effects (blowing you towards the wall with spikes OR sucking you + rocks into his mouth and then blow all out bit by bit).

If you decided to play offensive :
1. Countering his blowing skill, you should keep dashing towards sigma face and once you had the chance, do slash beast skill on him. Make sure you keep constant dashing and do slash beast skill when you had the chance. There is a risk that you might be careless and blown to the spikes, but its satisfying if you succeed.
2. Countering his sucking skill, you should make use of the 'blue' midget as a sheild to prevent you from being sucked in to his mouth. While he is suck, slash the rocks approaching from the other direction. Once he is done sucking, there is a 1-2 second delay, so quickly jump over the blue midget and keep slashing/air-slashing his face and the rocks coming out. I would say there is a 70% chance that the rocks flying out will hit you, but there is a 30% chance where you will not get hit and still able to damage him (I have done it before, so its possible). These are for brave people who dont mind losing hp for extra damage. After his rocks are all shot out, there is a 1-2 second delay before he disappear, so slash him while you can.
3. Afterwards midgets will appear, so just settle it with ryuenjin. His true form will appear next, being able to do 2 skills too. One of it would be the laser-scan skill, this can be easily dodge by standing close below him. Then keep doing ryuenjin, it will reach his head (You can also choose to double jump and do a spinning air-slash). His head is his weak point, so aim for it. Another of it would be, he doing a full ground laser-burst, which can be dodged by just doing a double-jump at the appropriate time. You can do a air slash on his head while double-jumping. You can differentiate these 2 skills by the positioning of the midgets, so be alert.
4. There is a simple pattern of his attacks. Midgets appear 1 time -> Sigma face form appears -> midgets appearance again -> Sigma true form appears. This repeats over and over again. However the skills he use is random, so i will not know when he will use what skills. I only know when he will appear, so i could be prepared.

If you decided to play defensive :
1. As his midgets appear, dont attack it, just stay away or dodge it. For his lightling midget, its possible to jump in between those lightling balls to dodge it. It may be difficult, but its possible with practise.
2. For his sucking skill, stay behind 'blue' midget, slash rocks in opposite direction approaching. After that, immediately jump and clinch on to the right wall to prevent the spat-out rocks to hit you.
3. For his blowing skill, just keep dashing towards sigma face and dont attack. This will take out the risk of being blown to the spikes. Just slash abit once he had stop blowing.
4.  For his true form, i would say carry on the same moves i mentioned above. Its safe enough and still able to do damage. It will take longer though, but if everything goes well, you may even defeat sigma without losing any hp.

For X,
I would assume you have Ultimate X. Below is the link to get all the upgrades for X.
I would advise you to get the plasma shot upgrade. When fighting sigma form 3, charged and shoot the plasma shot to destroy the midgets. It should be sufficient enough. However, if its not, dont worry as X is able to keep a distance with the midgets and still able to release his charged shot. Dealing with the lightling midget, i would still advised getting used and learning to jump between those lightling balls to dodge them.
1. For his blowing skill, i would advise dashing and charging alone. Until his blowing stops, then fire your shot (The plasma will applied additional mini damage to sigma). Its not advisable to dash, charge and shoot at the same time, you can easily get blown to the spikes.
2. For his sucking skill, you can choose to play defensive like how zero play defensive. You can also be offensive, however be prepared to eat some damage. You should be constanly charging whenever you had the chance. Make use of the 'blue' midget as a sheild for awhile, and plasma shot it. Then quickly charge again and immediately plasma shot sigma's mouth to destroyed the rocks before more rocks spat out. He may have spat out 1-2 rocks by that time, but its better than 1 whole load. This plasma shot at his mouth stops rocks from coming out and still do damage to his face form. Great and risky tactic i would say.
3. For his true form, since i have told you his attack pattern above. His weak point is his head. So by knowing when his true form will appear, jump and clinch to the left wall until the same level with his head, keep charging and shooting his head. This would only applies with his ground laser burst skill. For his laser-scan skill, i would say jump and shoot accordingly to the direction he scan his laser. For example, when he scans the ground, jump on to the midget and jump-shot him. Just dont let his laser scan you. This should be enough to defeat sigma, but i would say succeeding in the 1st try would be difficult. I recommend 3-4 tries.

Congratulations! You had beated the game! Enjoy the last cutscene! Once you had cleared the game, the final savepoint would be the space satellite, so you could fight sigma again. Ok, i am done with all my guides regarding megaman X4, hope it helps.

Have a nice day!
