This guide will walk you through each and every Original Mode boss.
Iron Fossil
The battle starts with Iron Fossil coming up to you face-first. Since it isn’t using the missiles yet, I suggest going above him and trying to get rid of the top fin. If you have Gaiden, you can just fire a bomb and alot of the scales will go away along with the fins. After a while, Iron Fossil will turn back and show its back fin. They then go to fire a Burst Beam. You could go for a counter, but my strategy is to make the back fin go down a bit. Once you see the bubbles, go back up a bit and once it fires the beam fire your own burst, only not directed at its burst. Iron Fossil will then turn again, only this time it is firing missiles. My strategy is to draw the missiles up or down and then fly away. Repeat and Iron Fossil should soon fall.
Hard Wheel
Hyper Jaw
Lightning Flamberge
Ancient Barrage
When Ancient Barrage swims back and forth at the bottom of the screen, stay a moderate height above Ancient Barrage and go inbetween the lasers.
When Ancient Barrage goes to one side of the screen, turns 180 degrees and puts up a shield, go to the very bottom of that shield and just sit there until it goes away. If you want to, you can flip. If you’re using Gaiden, I believe the shield doesn’t block Black Hole Bombs, so you can use those.
When Ancient Barrage does the same thing as before but always on the right and there’s no shield, go above the first two bouts of lasers and then go down below the third bout.

Violent Ruler(very easy finale)
Thousand Knives(easy finale)
Hungry Gluttons(normal finale)
Dark Helios(hard finale)
Great Thing(Expert Finale)
“When Great Thing enters the screen, it will be facing the player and begin using its main attack pattern, which will be repeated in parts of the fight. This consists of a pair of 3-way aimed spreads of red bullets and multiple homing arrow drones. After a while, it will move downwards until its top half is completely visible, and start firing 4 purple homing lasers out its top while one set of cannons fires twin orange beams. Midway through this pattern, the side horn will fire a non-Burst purple laser, then continue.
Next, Great Thing pulls back and reappears facing the screen, with its right flank facing the player. 3 top cannons will flip down. The first and third fire pairs of orange lasers, while the centre one fires bursts of 3 pairs of cube shots which turn into aimed grey shots when destroyed. Simultaneously, purple homing lasers will come out of Great Thing’s top and the horn will fire 5 arrow drones every couple seconds. After a while, the boss will tilt downwards and charge a non-Burst purple laser which fires upwards, then continue with this pattern.
When Great Thing reappears, it will stay for a while, then pull off into the background, leaving 3 of its minions in a vertical column and a spread of yellow orbs downwards. Each minion attacks in this manner:
Fires 4 way spreads of red bullets
Fires a purple homing laser that homes in 3 times
Fires a straight line of yellow bullets
Fires a Burst beam that lasts barely half a second
Teleports away
When Great Thing returns, it will resume its regular attack pattern, then pull off into the background, letting its entire left flank face you. These cannons will fire orange lasers and cube shots. After a while, the three cannons on its tail will charge and fire three non-Burst purple beams which sweep the left and top half of the screen. Midway through the beams, the minions will be summoned again, and Great Thing will leave.
When it returns, it will start its regular attack pattern again, but with a twist – the drill missiles are back! This time, they do not explode into small shots when destroyed, but instead leave behind a small, damaging explosion. However, not destroying them creates a large, long lasting explosion when they detonate. Use your Burst beam to handle these missiles before they eat your onscreen real estate.
After this, Great Thing returns, but with its top facing the screen. The two horns will continue spamming arrow drones, while the two side cannons send out pairs of orange lasers. however, the greatest threat is from the pink homing lasers, which are fired up and down alternately before they home in to you.
Finally, Great Thing fires purple lasers from its two horns to trap you. Next, it will do the exact same thing, but with one critical difference – the central cannon has popped up and is charging with red energy! By this time, you should know what to do if you can do it – pull out your Burst Beam and counter.
This should put Great Thing out of its misery, rewarding you with an ending for all your hard work.”
Just another reminder that this comes from the wiki.
Endings
You destroyed the ship, but now your ship is damaged beyond repair and you have to land on Darius by ejecting yourself from the ship with an Escape Pod.
Thousand Knives:
It’s a simulation, and you have to clear an entire sector on your own now.
Hungry Gluttons:
It LOOKS like you have to destroy an entire fleet on your own, but suddenly a bunch of yellow guys fly in and save the day.
Dark Helios:
It’s the Curious Chandelier ending from Darius Gaiden again. Basically, you destroyed all the enemies, but now Darius has exploded.
Great Thing:
The Belsar are sleeping now because you literally blew up their leader.
