Omega Pirate
The Omega Pirate is a boss located in the Elite Quarters in Phazon Mines. It guards the Phazon Suit.
First Phase
Knocking off Armor
Start the fight by boosting either to the left or right side of him and skip the cutscene (only possible on a save file where you have already watched it once). Doing this will start the fight with Samus slightly out of line of sight with Omega Pirate. Similar to the Elite Pirates, Omega Pirate will not start to attack you until he makes eye contact or until you break his first plate of armor. You can use this opportunity to rapid-fire missile all of his 4 armor parts and make sure he doesn't gain eye contact. Each piece of armor takes either 5 missiles or 13 plasma beam shots. A good strategy is to get each plate within one or two hits before breaking the first plate of armor. This will keep Omega Pirate from aggro/attacking you until all armor is ready to break. After breaking the third piece of armor, it can also be helpful to let Omega Pirate walk towards you and out from inside the Phazon Pool. This helps with the next part of his first Phase.
Trooper Skip
After knocking off all 4 plates of armor, Omega Pirate will fall down to the ground and appear to catch his breath. From here Omega Pirate will shake his fist at the sky and call down 2 random troopers from the upper parts of the room. A Power Bomb can be laid directly under Omega Pirate to skip this animation or if laid slightly differently, it can skip the troopers spawning entirely. To skip the troopers, roll under Omega Pirates head while he is on the ground. After Omega Pirate raises his head lay the Power Bomb and depending on your timing and positioning, you will either skip the animation, the troopers, or both. If you lay the Power Bomb incorrectly however, Omega Pirate will not skip the animation or the troopers and you will have wasted both time and a Power Bomb, and still have to fight off the troopers.
Managing Troopers
The color of the 2 pirates is random, but they will both have the same color for the first cycle fight. If they are Ice or Plasma pirates you should have enough time to kill them before the next phase begins. If they are Wave and Power you may want to leave one alive to focus on the 2nd phase. Know that you will have less time to fight the pirates if you went for the power bomb. Not all trooper AI is made equal either. Sometimes a trooper has a preference for long distance vs short distance combat. If there is a choice between killing either you should kill the long distance pirate who will shoot you constantly and simply avoid/dodge the melee heavy trooper.
Second Phase
Determining Pools
After vanishing, Omega Pirate will reappear in one of the three pools to regenerate armor. Omega Pirate is only vulnerable when he is regenerating armor and only with X-Ray Visor equipped. To determine which pool he will spawn in, Omega pirate checks the distance between samus and each pool and spawns in the farthest pool. Omega Pirate will not spawn in the same pool twice however which makes it easy know which pool he will spawn in. To always get Omega Pirate to spawn in the pool in front of you, simply stand between two pools such that the third pool is farthest away. After he spawns in the first pool and vanishes again, you can simply walk towards one of the two pools he didn't spawn in and watch him to spawn in the pool farthest away from you again.
Regenerating Armor
Omega Pirate regenerates armor by keeping track of two separate timers, Total Heal timer and Individual Piece Heal timer. Individual Piece Heal timer begins counting when Total Heal time > 2.5 seconds. After 1 second, the Individual Piece Heal Timer will regenerate a piece of armor. At the end of each damage phase Omega Pirate will automatically regenerate 1 amor. When a piece of armor is regenerated, the Total Heal timer will be reset to 0 if > 2.5, otherwise it is not reset. At the start of his first vulnerable phase, Omega Pirate starts with 2.5 Total Heal timer and both timers begin to count up. As Omega Pirate spawns into his next pool, the Total Heal timer will resume during this animation. If at the end of the animation of him spawning in the Total Heal time is > 2.5 the Individual Piece Heal timer will begin to count up. This leaves a very small window where you can damage Omega Pirate and end his phase with barely any time left on the Individual Piece Heal timer or the Total Heal Timer. Omega Pirate automatically regenerates 1 amor at the end of the pool so in spawning in the next pool Omega Pirate will be appear to instantly heal two pieces of armor. To avoid this happening during your fight, do not do damage too quickly during pool 2 or you may accidentally start pool 3 and Omega Pirate will heal all 4 pieces of armor instantly.
Dealing Damage
Typically Omega Pirate is fought with charged Plasma Beam, Super Missiles, or Power Bombs. A good fight will kill Omega Pirate in one cycle before he regenerates his armor completely. While the fight can be saved if his armor fully replenishes, it quickly becomes uncontrollable. This is because after regaining his complete armor, two more troopers drop down immediately and you have to completely knock off his amor again to deal damage. This means 2 more troopers again when his armor is fully knocked off. Typically two-cycle fights result in death or not even be possible due to a lack of power bombs. He can only be damaged during his armor regeneration and only while the X-Ray Visor is equipped. What strategy you use to damage Omega Pirate is dependent on what category you're running and how many Power Bombs you have to spare.
Plasma Beam
Charge Plasma Beam and lock onto Omega Pirate as soon as he appears and shoot. Release the lock on and look away to charge another Plasma shot. Shoot a 2nd fully charged Plasma shot to end the first pool. Repeat for 2nd pool and/or 3rd pool to one-cycle Omega Pirate.
Note: It is important to look away and avoid hitting Omega Pirate with a normal Plasma shot, otherwise it will end the pool without enough damage.
Super Missiles
Aim for the 3rd pool with power beam. As soon as Omega Pirate appears lock on and fire 2 missiles rapidly followed by a Super Missile to end the first pool.
For the 2nd pool, wait with fully charged Power Beam and fire a Super Missile as soon as Omega Pirate appears to end the 2nd pool. Repeat for any remaining pools.
Note: It might happen that Omega Pirate replenishes his armor in the 3rd or 4th pool already. This happens if you were too slow in one of the pools so he could replenish 2 armor pieces in one pool, or if you pre-shoot Omega Pirate too quickly as he spawns in. To avoid this from happening you should move towards Omega Pirate while shooting at him to reduce travel time for your shots, and avoid pre-shooting Omega Pirate before he spawns in.
Power Bombs
In 21% Omega Pirate is fought with only power bombs. This requires 3 power bombs minimum but 4 is better, as you will want to use one power bomb for trooper skip. After Omega Pirate disappears, morph and wait around the pool you want him to spawn in. When you hear a specific audio cue of him laughing, power bomb the pool and roll to the other side of the room to force him into the pool you Power Bomb'd. Quickly equip X-Ray Visor and Omega Pirate will take damage depending on how well you timed your power bomb. Rinse and Repeat for three pools to kill Omega Pirate in one cycle. Typically you wait outside of the pool for the audio cue however in "The Strat That Takes 60-Damage", pioneered by TomLube, you simply wait inside the phazon pool taking massive amounts of damage for some reason, as demonstrated in the video.
Alternate 3rd Pool
For the 3rd pool it is faster to do the Power Bomb strat where you have a Power Bomb to spare. This has the most potential to deal damage to Omega Pirate and can save a one-cycle in some clutch scenarios. If Omega Pirate is close to regenerating all armor or if you did not deal sufficient damage during the first 2 pools, a Power Bomb will be the only way to still save a one-cycle fight. Typically though, if it wasn't good enough to fully kill Omega Pirate, a few Plasma Beam shots will be all thats required. This can get sketchy however if it pushes Omega Pirate into a 4th pool.
