Ballos appears to be stout, with tan skin, a bald head, a flat, wide nose, and a wide mouth. He wears a white and green cloak with two red eyes vertically set on the front, resembling the eye on the Demon Crown. His right eye is also blood red.
Ballos is located in the Seal Chamber of the Sacred Grounds. After defeating the Heavy Press, the player must bring Quote and Curly through the hole created due to the Heavy Press' fall. When they reach the bottom floor, the player should bring them to the door on the far right and enter the Long Corridor. An encounter with Ballos' puppy allows Quote and Curly to pass through the corridor and enter the Seal Chamber.
Ballos lived at the same time a king was ruling over the land. Like Jenka, Ballos possessed magical powers and used these for the benefit of the people. He became well-received and grew in popularity over the king. As a result of their admiration for Ballos, the king became jealous and imprisoned Ballos. Ballos was brutally tortured, to the point where he allowed his magical powers to rampage. Ballos destroyed the king and reduced the kingdom to ashes.
Jenka saw her brother's actions and eventually exiled him to the floating island, unable to kill her own brother. At some point, Ballos created the Demon Crown under Misery's forced orders. Subsequently, Misery was cursed by the Crown, along with Ballos.
The player fights Ballos as the final boss for the "best" ending. When approached for the first time, Ballos introduces himself to Quote and Curly, anticipating his defeat.
Ballos has three major forms, the final part being two subphases. The player is required to deplete his health metre fully for each form. When one form is defeated, the next one appears almost immediately, with a fully restored health bar.
Flying around the top of the Seal Chamber, Green Devils appear at the start of Ballos' second form and can be killed for extra weapon energy, hearts and missile ammunition. New devils replace ones that get destroyed.
After Ballos speaks his final line, he stays in place and puts up his right hand. He then charges in a straight line to the player's left. His trajectory outlines a rectangle as he moves up and to the right, then back down again, though the height and length he moves at varies depending on Quote's initial position. When Ballos descends, a wave of bones moves outward along the ground. Bones will also rain from above whenever Ballos ascends.
Once a certain duration of time has passed, Ballos will begin to fly around in the air. He sends six vertical lines of white thunder to crash down on the ground consecutively, often near where Quote is placed. Crosshairs depict his targeted line of thunder. Ballos resumes attacking Quote by dashing at him if the player has not defeated him at this point.
It is not possible to obtain pickups when battling this first form. The amount of damage inflicted on Quote depends on the point of contact and during which subphase of the fight. While Ballos is dashing at him, Quote can take 10 damage, and while Ballos is standing, he can take 3 damage on contact. When Ballos is flying in the air and sending lightning bolts to the ground, each bolt can deal 10 damage if they hit Quote.
Upon depleting Ballos' health bar fully, he crashes to the ground (if in the air) with his mouth open and hands on either side of his head. He proceeds to leap into the air and through the ceiling, transitioning to the second form. At this point, green devils are seen flying around the upper half of the Seal Chamber.
The landing position of Ballos' second form is noted by a crosshair on the ground, located near Quote and Curly. Shortly after the signal, Ballos appears as a giant sphere that seems to represent his head. He begins to hop around in small horizontal increments. When he lands, a wave of bones ripples along the ground away from him. On every third jump, he pauses for a longer amount of time. Getting hit by the wave of bones subtracts 4 HP from Quote, while Ballos landing directly on Quote after a jump takes 16 HP.
In order to damage Ballos during this second form, the player must get Quote to shoot him through his eyeballs. Every other part of Ballos' body is invulnerable to attack. Successful shots come out the other side of his face, causing him severe damage.
It is possible to stand on the bottom right corner near Ballos' white eye. If Quote is positioned in such a manner, he can deal damage without jumping in the air. The player, however, risks getting hit by the green devils whenever Ballos jumps.
Ballos will then spawn out many eyes for protection against your attacks. Shoot them to make them all close up their eyes, rendering them invincible. Ballos moves around the walls and ceiling, dropping down skulls. The main body does no contact damage, but the eyes do 14 damage, so you'll need to try extra hard to avoid them. The Spur and Super Missiles are solid choices for this phase, but try to conserve some missles for Ballos' last form.
After all of the eyeballs are closed, the platforms will appear. Jump on them quickly; the spikes will rise! He then shows a grotesque form, that has his facial features giving way to what appears to be screaming people and skulls, perhaps as a reference to all the people Ballos killed. The Green Devils will be replaced by unlimited hordes of red-faced Butes that act as a combination of the flying Butes and the arrow Butes from Sacred Ground, the eyes will still prevent you from making much damage to him. You can shoot off four of them but you'd best be careful; they'll be bouncing all over the room! The eyes that are still circling around Ballos will deal 10 damage, and the eyes that bounce across the room deal 5. Ballos also spawn red-faced Butes from his face.
One common speedrunning trick that most people do is take damage from the spikes (Before Ballos cracks open and begins the final phase) without Super Missile Launcher, then boost up and onto Ballos's eye, unharmed by the invincibility buffer. Afterwards, the moment Ballos begins his last phase (When you hear a loud noise and Ballos cracks open) spam the Lvl. 3 Super Missile Launcher right in Ballos's eye. You only need 12 ammo in order to do this fully, and Ballos will be gone before you know it. If not, ignore everything else, stand underneath him regardless of the spikes and eyes, and blast whatever you like as fast as you can up at him. The spikes do little damage, 2, to be exact, so as long as you have enough HP to withstand in the spikes, do that. If you don't like taking damage from the spikes, or if you don't have sufficent HP, stand on the moving platforms and attack Ballos from there. If you have the Lvl 3 Blade after all this trouble, you can use it on Ballos and if will deal good damage to Ballos and the eyes. However, arrows from the Butes and the bouncing eyes pose a threat because even the slightest hit will de-level the Blade.
|Once Ballos is defeated, the Nikumaru Counter stops and the player hears the words of Ballos' pain (HOT... HOT... CAN'T BREATHE... SO PAINFUL... HOT... IT HURTS...) The walls attempt to crush Quote and Curly as a last resort. Then Balrog jumps in to save the two robots, and smashes his way through the ceiling as the walls come together. Quote, Curly, and Balrog decide to live in a peaceful place with a view, and the credits roll as Balrog flies them there.|
