As their name implies, they are the bosses of the various Chapters in-game. Each one of them (except for Lance) are corruptions of the Inhabitants' hearts formed from a bad memory happening from the past. They are all composed of different Costumes from their respective Chapters (although very corrupted compared to what the Costumes were beforehand) to provide deadly attacks. Each of their composition also appears physically and often fits the theme of each Chapter.
In total, there are twelve Nega Bosses and one other boss (Lance).
Gameplay[]
After completing and obtaining the two heart fragments from the Heart Trees, you can fight the Nega Boss of the chapter. There are no checkpoints during the boss fight (also can be considered as an Act), so you can not change your Costume, exit the boss fight normally, or re-spawn. If you lose all your Costumes and get hit again, you will be sent back to the Isle of Tims, unlike other Acts. You can exit the boss fight though the menu (except for Lance's). You can also choose your desired Costume(s) before entering the level, the same occurs when you enter a Third Act.
All Nega Bosses need three hits to be defeated, two Costume Crystals and Keys are provided in the boss fight, and if you lose the specific Costume while fighting, you can get another one when it spawns. Lance's fight has three phases, two (1 and 3) being where you hit him three times, and one (2) where it transitions to the third phase, and you lose all the Costumes you brought into the boss battle yourself. You can obtain three Gold Balan Statues from each Nega Boss fight by doing specific attacks with Costumes found in said Chapter.
You can bring a second player via Local Co-op mode into any of the boss fights.
List of Nega Bosses[]
The specific strategies of a boss can be found on their respective page. Lance is included in this list, but he is not considered a "Nega Boss."
This Nega Boss was born from the heart of a diver who nearly drowned in an accident with a dolphin. She uses water-based weapons and can summon electric jellyfish.
Born from the heart of a young inventor who nearly died in an attempt to fly, this Nega Boss takes on the form of a warplane and uses attacks based on one.
This Nega Boss is an avian horror that wields the power of winds and can drop eggs that summon negative energy. The avian horror appeared when a woman who loved birds watched a forest get destroyed.
This Nega Boss is a feline monster that can control time and attacks with rocket punches, born when a young girl thought she lost her cat in a dreadful car accident.
This Nega Boss sprung forth from the heart of a clown who was scared that a princess would reject him if proposed to by him. She wields cannons and can slam the ground as well.
This Nega Boss takes on a draconic fire hydrant form. He traces his origin to the heart of a firefighter who was hampered by igniphobia. When fighting him, watch out for the flames!
This Nega Boss was born when someone tried to clean a town park but his efforts to do so were hardly noticed. Hooverton uses his invisibility powers to sneak around his arena and attack enemies from a distance.
The main antagonist of the game. Lance uses shadowy powers during his battle as well as duplication. After enough damage, he transforms into a shadowy draconic monster that dishes out more damaging attacks.
Trivia[]
Whenever the bosses suffer their first or second hit, they will perform a specialized attack in their rage [not counting the second hit having come from countering the rage attack].
To restart a Chapter's Act(s), you'll have to defeat the Chapter's boss. (Though another way to restart levels have yet to be found.)
The Nega Bosses' Japanese names were named as such to make it more understandable for a Japanese audience, the same goes for English names as well.
The term "Nega Boss" comes from the Balan Wonderworld creator presentation video.
