What if NOSK were in rivals?
Stage intro would be his long transform into his form. His taunt would be his battle cry. like grimm, it would stun nearby foes.
His jab would be 2 scyth slashes and it'll end with a bite.
His dash attack would be quick closing with his scyth-like hands, as in a last resort manner of a predator trying to catch his prey.
The side tilt would be spitting an acid blob forward, resembling an aspid.
Up tilt would be expandong his back spikes,
And down tilt would be changing his head into a dirtcraver (one of the residents of deepnest, and a victim of his) for a quick bite. He would also be able to crawl.
For his side strong, he would charge by guarding his face and then launch forward, just like the stalking devout, a resident of deepnest and the largest victim nosk caught.
For up strong, he'll jump high into the air, only to pound the ground with massive blow, the more you charge, the stronger the attack.
For down strong, he'll roar and by that, will cause several orange blobs to fall from the sky, covering both sides of nosk. The more your charge, the wider the attack is and more blobs will cover the area.

His netural air would be expanding all of his limbs to all directions.
His forward air would be a quick slashing of his hands from up to low.
His back air could be bumping the opponents with his core-like heart.
His up air would be expanding all of his back spikes upward,
And his down air could be dropping one blob of orange infection, resembling his "rain" abillity.

Netrual special would be summoning a balloon of infection that homing toward the closet enemy.
Side special would be his dash attack. He'll keep running until he jumps or parry. Meaning he keeps running even if he hitted foes and cannot stop at ledges.
His up special would be changing into his winged form for recovery, giving great mobillity in the stage, and then freefall (like captian olimar's from SSBU up special),
And For down special, he'll use eruption. This attack will have a cool down as nosk need time before using it again.


For colors, the main changes will be his heart, giving how nosk is already faceless (as his title says) we will mostly change the colors of his core. There'll be orange, red to resemble grimm, yellow to resemble godhome, green to resemble greenpath, blue to resemble bloodlife, purple to resemble deepnest, white to resemble the pale king, and black to represent the void.
