Project IV

Summary
A 'creation' of Science Guy, made to take over Dogeku to destroy all of existence, but oh boy how that backfired-

He was an antagonist but slowly became a Meme Fighter after his bond to Dogeku strengthened, and he came to more-less know the Meme Fighters are friends rather than foes

Ever since he got the stones to spite Nightmare, the stones seem to have a natural bond to his right arm, in which he regularly uses the stones in; despite this bond, the stones are currently in the hands of one of the Meme Fighters for safety against a looming threat, specifically aimed towards the stones

As of current, Project IV's whereabouts are unknown, and have been for nearly half of Season 8 and all of Season 9 up to now

Story
Just told you it, but if you wanna know his past he basically came from an asteroid chain which hosted the last of the remaining Symbiotes in the multiverse that were pushed to near-extinction due to the lack of hosts, and he, as well as the youngest of his race, were taken to Science Guy's lab as per [REDACTED] 's instruction

From there, no one knows exactly what happened, but the Symbiotes, now known as the Projects, were given life after Science Guy's undisclosed modifications, to which they escaped days after

Although the others yearned for freedom, Project IV was the only one to stay

The rest is history, for the most part

Appearance
As a symbiote, his body is mainly made of biomass, in which him in specific dons said biomass of mostly black and a bit of matte, and a mask that was damaged and later lost, albeit him not necessarily having concern for it in later seasons

Forms
Full Power Base

Super Symbiote (A chain of forms picked up from being attached to Dogeku, which mirror Super Doge's main lineage of forms (SSJ-3); each form gives him a boost equal to that of the Super Doge forms, each respectively with the same multipliers and almost the same auras aside from color; whilst FP forms contain the transformation into Project IV's body to use as he pleases, non-FP forms cause his body to become more ridged and primal, giving him sharp teeth and teardrop-like eyes)

Random Purple Form (Super Symbiote but purple replacing the matte with a Super Doge God aura with purple and black replacing the red and orange; Project IV's equivalent to Super Doge God, and origins are mostly unknown)

Supressed Random Purple Form (Random Purple Form supressed to an aura and making Project IV look like an all-purple base form of himself)

Golden Form (Project IV with a gold aura and skin color; Project IV's equivalent to Super Doge Blue)

Pure Golden Form (basically Golden Form Evolved; it has the appearance of basic Super Symbiote with shades of gold entracing the dents in the skin, his eyes a neon gold as well with a steam-like aura to match; this form was made to be a last resort, as the form would push his limits far beyond )

Stone Form (basically an aura around his body that makes his limbs match the stones)

Meme Instinct (starts off as Stage 1; this form makes the matte parts of Project IV a light grey, but transitions to MUI, which makes Project IV's skin white and his right arm,leg and head light gray, although this form is on par with UI Stage 2)

Techniques
Body Manipulation (the ability to make things out of self and in extension able to make limbs and body parts stretch to infinite lengths)

'Possession' (the ability to take over people and make them into hosts against their will)

Symbiotic Copy (the ability to copy techniques and form designs the longer the symbiote is physically and maybe emotionally bonded to the host)
