The only official names of this boss that is referred internally are ' Boss2' and the name of the boss level that appears in, ' Barracuda'.This boss's appearance bears some similarities to the symbol of the Illuminati, Bill Cipher, or other similar characters or icons, notably when the boss evolves into a pyramid.At the end of the level, the boss explodes into a shower of triangles and is never seen again in the game's storyline. It later evolves into a pyramid during the level, attacking the player using circles, spectrum bars and triangle-shaped snakes (better known as pyramid snakes). It is a pink triangle-shaped boss with one eye on it, which often squints whenever it attacks. Its connection to the main antagonist is unknown.

It also might be connected to the triangles that the player collects throughout the game, although this may be a coincidence. It battles the player during the same level, but it is never explained how or why this boss battles the player, although it is assumed it is one of the three triangles from the so-called 'Tree of Life'. Just Shapes & Beats manages to be something much more than just a game with funky songs and colorful graphics.This boss is a minor antagonist that only appears in its debut level, Barracuda. The heroic tale of this small, blue square adds a sense of purpose to the whole game compared to many other musical games where the only objective is to clear stage after stage. Just Shapes & Beats follows the story of a cute blue square that is on a mission to stop an evil shape from causing havoc and destroying everything in its path. There is a story behind your journey through the tidal waves of music and while it is not as dramatic as you would expect, you will find the plot to still be pretty heartwarming. You would be surprised to find that the game actually has a background story and is following a plot. You will be trying to survive and win the game by simply avoiding attacks and surviving until the song has finished playing. To make things even more challenging, players are not allowed to fight back and defend themselves. The livelier the songs, the more erratic and unpredictable these projectile objects will be and of course, the harder they are to evade.

The movements of these obstacles are based on the music that is playing so if you are listening to an upbeat tune, expect everything to be fast-paced.
