This list of bosses shows the same stats as in the unlockable weapon information in the game, but with strategies on how to beat them.
The bosses generally move slower on Normal difficulty, but the rest of their skills and stats are the same unless otherwise noted.

There are several ways to take him out quickly. Get a Buster gun with 25 machinegun ammo and an Attack of 3, and he won't even get to move. The Hyper pulse (Resonance detonator + Pulse cannon + Crack 6) and Spread rockets (Shotgun + Rocket launcher + Crack 5) are also pretty good. If it wasn't for Iji's mercy invincibility, Krotera's rapid-fire MPFB would deal 72 HP damage, which is nearly enough to take out a Komato Annihilator.
To avoid fighting Krotera altogether you need to keep the Tasen truce; see Sector 3.
Asha will drop one Electromine for each hit point lost, which remains permanently on the ground and deals 2 HP damage.
If you have the Plasma cannon (Pulse cannon + Shocksplinter + Crack 8) already, it'll make short work of Asha on Normal, instantly defeating him if your Attack level is 9 or higher. He'll dodge it very frequently on Extreme difficulty though.
The Nuke (Rocket launcher + MPFB Devastator + Crack 9) defeats him instantly and nets you a Supercharge. You can even have the Nuke equipped and hold the fire key during the intro chat - keep holding it when the fight begins and you'll win immediately. Hold left as well and you'll be blown towards the Supercharge.
Defeating Asha here doesn't count as a kill, and the fight can't be avoided.
One strategy for survival is to hang around the middle platforms and react to its attacks. Always assume it will fire the Plasma cannon next, and remember that Iji moves vertically very quickly. Jump to make Proxima pick up vertical speed and miss with its Plasma shots, or aim its MPFB into the ceiling, etc. Kick Proxima into an electropad when it falls to the floor, then lure it into the other one. The MPFB Devastator and Plasma cannon are good for moving Proxima around as well.
The terminals to activate the electropads power up again after Proxima's AI executes a certain numbers of orders. In order words you cannot simply stall by trapping it against one of the bottom walls with kicks - it needs to attack a few times, or at least attempt to attack. If it's is blown across the room enough, it'll lose its bearings and start canceling attacks.
When Proxima is trying to move somewhere without attacking, it may react to heavy blows and kicks by performing an "Angular shift", moving it a fair distance vertically. This makes it very hard to juggle against a wall with explosives.
Alternatively, bring an MPFB Devastator with at least 15 ammo and an Attack of 10. This is enough to destroy Proxima without using the electropads, which gives you a Supercharge. The Velocithor helps too.
If you're curious, jumping into the electropads deals 3 HP damage. Proxima is also mechanical and doesn't count as a kill.
When Iosa starts flashing, duck or get up to a platform; her Velocithor deals up to 10 HP damage. To drain her health faster, use the MPFB Devastator or Spread rockets (Shotgun + Rocket launcher + Crack 5) and jump out of the way immediately after firing. Of course, to do this with the MPFB requires a Strength of 10. Retribution (see Misc secrets) is also extremely powerful here - with an Attack of 10 it can take off at least 150 HP, if you activate it when Iosa's right on top of you.
When her HP drops below certain thresholds, Iosa will fire a Crawler as her next attack. These red spinning projectiles cannot be reflected or destroyed, and will remain in the room for the remainder of the fight. She fires one Crawler on Normal difficulty, two on Hard, and three on Extreme and Ultimortal.
When the Annihilator exoskeleton explodes, Iosa jumps out to bring the fight to the next stage:
Look at the "safe" arrow to know whether to walk left from her jump attack, jump over her supermove, or duck under her regular swipe. After ducking the swipe, stand up and kick her before she uppercuts. Keep kicking her until she hits the wall, at which point you'll have 10 seconds to crack her Nanofield. Be warned: you can kick her backwards 8 times on Normal, but only 7 times on Hard and 6 times on Extreme/Ultimortal, meaning you'll have to duck her regular swipe further to the right in the room. This in turn means you'll have to work your way to the right without Iosa hitting you. It only takes one successful crack to win, though.
Iosa can perform at most four attacks before being guaranteed to use her normal swipe as her fifth attack. This counter resets when she does use a normal swipe.
Bring Ansaksie along to the fight, and she will kill Iosa once the battle has ended (see Sector 9). Without recruiting Ansaksie, if you have 270 kills or less when defeating Iosa, you will be given the option whether to kill her or not. If you have over 270 kills however, Iji will shoot automatically.
Asha can literally dodge everything, but would rather die than run from someone using a Shotgun or Buster gun - so these are the only weapons/attacks that can hit him. Stand still and wait for Asha to appear, then react appropriately. If he appears standing behind you, fire the Shotgun and duck. If he appears in front of you charging his Plasma cannon at chest height, fire the Shotgun and duck. If he charges the Plasma cannon at leg height, fire the Shotgun and do a short jump. When he appears in the center of the arena with a glowing fist (megasmash), do a high jump to avoid the shockwave. When he clings to the wall (plasma rage), duck under the plasma bolts. When he appears airborne in the center of the arena holding a gun (plasma vortex), duck close enough to him not to get hit by the bolts, or do a high jump if you're feeling skilled.
After he's taken some damage, half-transparent afterimages of Asha start appearing. Just ignore them. Bring a Buster gun with lots of ammo and an Attack stat of 10 to this fight to win fairly easily. Also, his electromines deal 2 HP damage if you touch them.
Tor's tier 1 and 2 weapons each have five levels of power that slowly increase every time you dodge them. If you're hit by a weapon, he increases the probability of firing it, while the probability lowers again if it misses. Tor's weapons begin on level 1 on Normal, 2 on Hard, and 3 on Extreme/Ultimortal.
Of the tier 3 weapons, Death hail (blue lasers) and Eruption (fast red wave) have three power levels, which increase by 1 when they're fired. They begin at level 1 on Normal and never go above 2, while on Hard they begin at level 2 and reach level 3. On Extreme/Ultimortal they're permanently set to level 3.
If Tor has three chargeballs and his HP is over 750 on Normal, 825 on Hard or 900 on Extreme/Ultimortal, he'll fire the Phantom Hammer. It turns Iji into mist and completely wipes all of her stats - but can be avoided by doing a short jump over his shockwave stomp. If his HP is too low, he instead uses Nanostorm which fires a stream of exploding particles each draining 60 armor and hitting you for 3 HP damage if your armor drops below 0. Just keep moving to avoid it.
Tor is immune to armor-damaging weapons except the piercing CFIS and Velocithor (MPFB Devastator + CFIS + Crack 10), taking full damage from those and anything explosive. 50 MPFB shots with an Attack of 10 will take him down on Normal difficulty without the need to reflect anything.
If you fight Maximum Charge Tor (see Sector X), he starts out with 1200 HP and all weapons at their highest power level, plus he drops only one Health pickup when hit by a reflected chargeball, and he releases two Skysmashers every time he lands. Surviving this on Ultimortal, where no Health is dropped and you're restricted to only the Resonance reflector, is perhaps the toughest feat in the game.
If your kill count is over 300 when defeating Tor, and you did not spare Iosa in Sector 9, you will be given the option whether to kill Tor or not (see Sector X). Otherwise Iji will not kill Tor after defeating him.
Here's a damage chart for reflecting Tor's projectiles:
Reflected chargeball: 83 HP
Reflected Fractal rocket (brown splitting rocket): 7 HP
Reflected Ragebomb (cluster bomb): 7 HP
Reflected Tyrian claw (spinning purple blade): 12 HP
Reflected MPFB projectile: 3 HP (modified by your Attack stat, the others are not)
