Blixer

I'll take over all of Paradise... And make you proud!" -Blixer, referring to Barracuda

Blixer is the main antagonist of The Pink Corruption, being responsible for the titular virus that started to spread across the land ===

Blixer was a nice beige monster at first, as Pyrare informed the other caretakers and heroes in Episode 5. However, as Dub got along with Barracuda, Pyrare's son, Dub made the virus. Barracuda died for an undisclosed reason and this transformed Dub into what he is today.

Blixer is a vile monster who wants to continue and finish Barracuda's plan. He plans to corrupt as many shapes as possible and make all of Paradise bow to him.

Powers

 * Duplicating - Blixer could duplicate Cubic while he takes care of Cyan.
 * Shield Star - In Episode 2, he shielded and reflected Matured Cyan's blast.

Appearance

Other than being a different color, Blixer seemed to have the same type of general clothing as his present self. Considering that he is a monster, it can be assumed that he was larger than other shapes.

Not much can be said about his appearance because the only image currently available of his past self is a silhouette. However, several features can be made out. His ears appeared to be larger, and his head was almost symmetrical because of his hair. He also had an almost permanent grin.

First Phase
Blixer is a large being, towering over most of the trees in Paradise. Small triangle horns/ears are almost hidden in his wavy, yet spiky hair. His head is a circle with a single eye, along with a few triangles to indicate his mouth, occasionally being replaced with stripes to form a menacing smile. His arms are made from four circles with six spikes emerging from them, along with a smaller circle around where his shoulder should be. His hands are also spiked circles with a black circle in the middle, with three smaller circles for his fingers.

He wears a dark, ragged cloak with torn pink sleeves and a pink gradient at the bottom, as well as a pink bandanna around his neck. Seen over his dark pants are two pink boots, both complemented with light pink stripes around the neck of the boot.

After eating the triangles from the Cyan Tree, Blixer's features have noticeably changed. First, he gains another eye with both having white irises and/or pupils (like New Game). His hair grows longer, and his triangle mouth is replaced with stripes. His stripped boots are replaced with ones that are black and studded down the sides. He grows a few extra triangles on the top of his head, and he also earns himself a ragged pink cape and a guitar.

It is possible that Blixer was a guitarist before he befriended Barracuda, as he is shown to be skilled in it.

As mentioned by Pyrare, how the Pink Corruption was made is a question only Dub can answer. As of now, the answer is yet to be revealed.

It is noted that Blixer is much taller than the trees around him and possibly taller than Pyrare.

It's implied that Blixer has eaten the triangles from the other Trees as well, quote "Let's see what Cyans can do."

It is unknown what Blixer could have looked like when he was uncorrupted but he was a beige monster when pure/not corrupted.

He is the character that appeared in the Pink Corruption Continued logo.

There is no way of knowing what Dub will look like in his Annihilation form.

Gender
Blixer Is A Boy, as confirmed as in the original game of Just Shapes And Beats.
