I just had a cool idea for a whole scenario and headcanon-
Syringeon has gone into his "Hellish" form one single time since he was made, the first, last, and only time he's ever done so.
(I have tons of ideas and headcanons about givanium and what exactly the "Hellish" forms of the characters are, though I haven't really touched on them in any of my posts yet. Basically though I headcanon a character mutates into their Hellish form via one of three mean; either an overabundance/overdose of GV ((i.e. LittleBeak falling into the barrel)) which can be undone via purging the body of the excess GV, a drastic lacking of GV like blood loss from an injury ((a character getting hurt and then acting like when a boss fight has a 2nd phase)) which can be undone just via healing the individual back up, or the outlier of the three being that odd "modified Givanium solution" that's mentioned in notes)
Anyway though, new headcanon/idea; Syringeon has mutated into his Hellish form one single time in his life, and it was in order to protect his family and friends on Layer-4.
I had an idea for a scenario that happens around the middle of the failed-revolution-arc, a team of armed site personnel are sent down to Layer-4 in an attempt to quell the mutants growing revolution, quelling quickly turns into threatening and the situation spirals into a full on attack. Most all mutants who can fight back do, but things go wrong and everyone ends up needing to fall back to the kingdom. Syrin ends up staying behind to buy the others more time.
Syrin heads back to the attacking armed force of humans, manages to easily take a few down, but is quickly and severely outnumbered by the site personnel and surrounded. He bides for more time by getting into an argument with Uthman, who's also there, but not even that plan holds out for long before Uthman is giving orders for the guards to take down and capture Syrin so they can continue onto the kingdom and the other cases.
Syrin starts panicking as the guards start to close in on him. He's damn near impossible to kill thanks to his hammerhead worm genomes letting him heal and regenerate, but he can still be subdued and restrained, and if that happens then the guards will get to the kingdom. Not only will his family and friends most likely get hurt, but he won't be there to heal them up either. Syrin is panicking and wracking his brain for a way out, before a realization suddenly hits him-
He and the guards are currently at a location in the facility that's an upper floor overlooking a lower floor, and not only that, but there's a multitude of very large GV barrels scattered around the lower floor bellow. Some of which have been left open with no covering. Syrin knows what he has to do, and is cringing at what he knows is about to come, but knows that he has no other choice if he's gonna hold the humans off to protect everyone.
Syrin makes a break for it, managing to duck and dodge past the surrounding guards and getting only a few gunshots as a result, before running full-tilt to the nearest balcony and just fucking vaulting over the railing. Diving headfirst into an open vat of GV.
His last thoughts before losing consciousness are "I won't let them get to my family." followed by "It hurts it hurts ithurtsithurtsITHURTS-!" before the world went black for him.
The guards and the site personnel all crowed around the spot of the railing the case had jumped over, and look over the edge at the open vat of GV down below that the case had disappeared into, their blood running cold as they realize what's about to happen...
And after a moment, a hand emerges from the teal liquid and grabs the edge of the vat, mirrored by a second hand on the other side. Followed by another hand, and another hand... and another, and another, and another, and another. A horrifying amount of hands and arms emerging from the GV to grip the edges of the vat, while a horrifyingly large and mutated body hauls its way up and out of the liquid. The mutant now more than long enough that once his pendulum-like head is pulled up, he towers over and looks down on the humans on the second floor. And just-
