Boss

Bosses are enemies that appear in Smash Hit. They are exclusive only to Mayhem Mode, and do not appear in any other Game Modes.

First you pass a number of crystals, which you can destroy for more balls before the boss. When a boss is encountered, they will hover in front of the player, and will periodically rotate and retract back. When the boss attacks, the boss will shoot small glass cubes from its cannon (which lights up to signal an attack) at the player, which can be destroyed by throwing balls at them. The only way to defeat a boss is to destroy all of the glass sides, except for the cannon (which is indestructible) that shoots the cubes.

Once destroyed, the boss will collapse and fall (smoke also is emitted from the cannon). Only when the boss is destroyed (the room shakes as well) may the player proceed to the next checkpoint. From checkpoint 5 to checkpoint 10, there is a number of crystals at the end.

Overview
Every checkpoint in Mayhem will have its own segment specifically for the boss fight. More than one boss can appear in one boss fight, and some fights also have a ring of Glass Panes to shield the bosses.

Types
Within the boss segment, a sequence of crystals will precede the fight, and sometimes afterwards, with the exception of Checkpoints 2 and 5, due to them having a Break Point at the end of their checkpoints.
 * Single-cell bosses are comprised of only one cell, and are relatively easy to destroy. They have five glass sides.
 * Triple-cell bosses are comprised of three cells. These bosses are harder to destroy than single-cell bosses due to more glass (13 glass sides).
 * Quintuple-cell bosses are comprised of five cells. These bosses have the most glass (21 glass sides) on them thus are hardest to destroy. They have

Artwork

 * Their glass resembles the color to the stage, which will [not really] help to camouflage themselves.
 * Apparently, the cannon where the boss shoots cubes does not resemble the color, just a full shade of black.
 * When the glass is smashed, it changes to a grey color. A black surface is revealed underneath.

Trivia

 * The cells of glass are implied to be the energy provider of the boss, as destroying all the cells causes the boss to lose its ability to hover and fight back.
 * Most bosses with added defenses (more glass) prioritize the defense over offense, thus firing less glass cubes than weaker ones.
 * One exception to this is Checkpoint 7's boss, which is a Quintuple-cell boss that fires like a Single-cell boss.
 * Only one cube is dangerous, yet there are multiple fired from most bosses, usually three.
 * Bigger and stronger bosses are often seen behind the weaker ones (i.e. a Quintuple-cell boss behind a Triple-cell boss), which is similar to the "Big Brother is Watching You" effect.
 * An exception would be Checkpoint 5's single-cell rear boss, behind the stronger triple-cell front boss.
 * Strangely, the boss(es) in the back can still be hit, albeit with a precise shot and timing. Don't expect to hit all the glass completely in one shot, as the rear bosses do rotate quite fast, mostly when the front boss isn't at all, and are very far behind. In the case of the Checkpoint 10 boss, the quintuple-cell boss in the back is so far you can hardly see it, until you defeat the single-cell boss in front. Then it will move forward in firing range.
