Soon to be added.
When the Glitch broke over the Underground, those closest to it suffered the most. The Resort and all within it erupted into chaos, overtaking and nearly destroying Mettaton’s EX form in their madness. Catty did not survive the first wave of the Hunger, falling to a pack of starving monsters while attempting to forage through the garbage for food for herself and Bratty.
Bratty lost her mind when she found her friend being torn to pieces by the ravenous pack, and killed them all with the gun she had in their inventory with nigh military precision, saving most of Catty's nearly dead body. She sat with her comatose, vegetative friend in their alcove for months, rocking and talking to her and laughing hysterically, attempting to feed her any food she found or harvested from passing monsters, but to no avail.
Eventually, she ceased to recall anything but Catty, anything even about herself. And in the end, when her mind finally broke entirely, she skinned the cat monster, donned her fur, and, after consuming her entirely, ventured to New Home under her guise. On her journey, she adopted not just Catty's tendencies and voice, but her name as well.
She currently holds a section of the Capitol in check, manipulating and bossing around lesser monsters with sheer charisma. She wields the gun she used to save Catty and a pair of machetes. When she can’t find ammo for the firearm, she slashes into her prey/enemies with said machetes, grinning through razor-sharp fangs and Catty’s empty eyes at her target. She lost a large chunk of her tail at some point, likely chopping it off to eat herself, and instead has sewn Catty's onto the end of hers.
Despite her madness, she is incredibly clever and conniving. She can talk even the most insane monster into obeying her will.
Burgerpants currently holds sway in a section of New Home, a cruel and maniacal manipulator of those lesser than him. After his escape from the Resort, and his near murder of Mettaton, he initially secluded himself in his home and scratched almost all of his face off in his growing madness and despair, baring bone and muscle and tearing away his eyelids completely. His appearance now far more sinister and terrifying, he emerged, starving and insane, to a city ruled by marauding lesser monsters, hunting for boss souls and easy prey.
As a common monster, he was not targeted, and instead cordoned off his neighborhood in quiet times, trapping his prey/cattle in a makeshift pen of blocked off alleys and high walls to secure not just a source of food for himself, but a gaggle of willing and easily swayed monsters to bring in more “members” for him to “protect”. He feeds them, keeps them as nearly mindless slaves, and prowls the destroyed streets with them in tow, where they not only protect him, but pursue prey for him. He barely has to lift a claw for himself, but the monsters under his care are either too far gone to notice, or just don’t care.
Burgerpants has dubbed himself the Eye, citing his never closing, bloodshot eyes, but merely goes by Master to his pets. His face is a mass of yellowed bone, pus, scars, and patches of fur, his body covered in scars from his own claws, and he wears parts of the armor of a fallen guard as representations of his rank among his underlings. His power is like a drug, and thanks to his Village, he is almost never in fear for his own life. He lives in relative comfort, completely immune to the bloodshed and carnage of the rest of the Capital.
End of The Lesser Monsters
The defacto leader of the amalgamates, and the most powerful of them all. She has unnatural power over the magics of other beings, though she has to be very close to use it. She moves extremely slowly until within attacking distance. She has only become more terrifying with very few malformations, namely the further melting of her form. She now drips whitish ooze continuously, draped with strings of gooey, lemon scented slime. Occasionally, another new face forms within her body, strangely resembling the late Doctor Alphys. She screams unnaturally when within striking distance of prey. Otherwise, she moves almost completely silently. The only monster known to have escaped her tremendous, deadly jaws is the leader of what remains of the Royal Guard, though not without terrible injury.
It very rarely leaves the lab, as its form has suffered the most from the effects of the Hunger. It seems to have been fragmented across hundreds and possibly thousands of planes of existence, as it is incapable of existing fully at only one point in time unless completely focused on something, such as eating. Once it has cornered prey, it will then take on a form so horrific and twisted that even the other amalgams cannot stand to be around it; a terror of broken limbs, fractured fangs, and headless corpses devouring the wretch it has cornered. The most consistent of its appearances in this plane is a large mass of white butterflies, or a single floating eye with gnashing jaws as its iris. It speaks in half-formed stutters, moaning the name Undyne, “I’m sorry”, and “Save me” when searching for food.
Endogeny has become a relentless tracker, braying constantly once it has discovered the scent of a monster nearby. Its form is largely unaffected; it remains a convulsing, foaming mass of dog monsters lost to time and space. The liquid it excretes has become a deadly, acidic contaminant that can eat through steel, and its dedication to the chase is unending. You cannot throw off Endogeny’s pursuit unless it is eating, or if anime is playing on one of the lab monitors.
Did not survive her time confined to the labs. Without interaction from her son and husband, she succumbed to oblivion and receded into the mass of other monsters she was composed of, never to be seen again. All that is left of her is a sea of churning faces and fragmented voices, all crying out in agony and wretched distress. They roll across the ground in an undulating mass, seeking out the warmth of living creatures to consume. Items from those it has eaten remain within its mass, namely being clothes, jewelry, and personal affects. A pair of glasses and a ripped lab coat surface on occasion.
All the Amalgamates, barring Endogeny, have a little piece of Alphys in them…
-And for the Alphys thing… Eh, she’s sort of in a limbo state. Not really alive, but not really dead either. My guess is the Amalgs assimilated bits of her soul when they devoured her.

End of The Lesser Monsters
Alphys retreated to the Lab, once Undyne secluded herself in Waterfall and refused to see her, afraid of what the Hunger was making her into, and attempted to find a way to force a Reset on the world, to take it back before the Glitch. The days grew too long and dark for her, though, the impossible task of finding more Determination than Flowey now possessed pushing her further and further into paranoia and depression, and before the Hunger truly set in for her, she released the Amalgams from the True Lab and allowed them to devour her, blaming herself entirely for Flowey’s rise to power and existence in the first place.
This was what Undyne found, when she managed to drag herself from the early slime of the Dead Swamp, her partner’s body being feasted on by festering, starving beasts, and managed to rescue her lab coat from the Amalgams before fleeing back to Waterfall.
Muffet has become queen over her demented kingdom of lava pits and webs, scattered bones and diseased, twisted machines. Her precious pet has long since been consumed by her and her family, and it’s cracked, empty carapace is now a home for the swarms of mutated arachnids. While the Amalgams, unable to be contained by the Lab, rule one half of Hotland, Muffet holds sway over the other half, uncontested and reigning supreme.
She has become the mind behind the hive, the speaker and controller of those smaller than her. When her lovelies cannot find food to feed her monstrous appetite, as her body has grown to enormous size and she is nearly incapable of moving on her own at this point, they sacrifice themselves to her unending Hunger.
Her victims are brought to her alive, screaming and horrified by the sight of the wreckage of the former beauty. They are then subjected to a poison of a dreadful sort. One that deludes them into thinking they are safe, whole, and in their most fantastical memory. This relaxes Muffet’s prey, which enables her and her dear sisters to feed without too much trouble.
Any monster foolish enough to harm one of the smaller spiders isn’t given the toxin, though. They are instead consumed with extreme prejudice, given every ounce of pain they so justly deserve.
Mettaton is a shattered husk of himself, his own machinery integrating with his soul inseparably and stealing all but the dregs of his mind and memory. He was trapped inside his Resort when the killing started. Burgerpants had always hated Mettaton with a passion after having his dreams crushed, and the moment he had the opportunity, the Resort in chaos with the violence and confusion of the early Hunger, he flipped Mettaton’s switch and shoved him into a mob of rioting monsters before fleeing to the capital. As a result, the former star was nearly destroyed by the mob of crazed monsters trapped inside with him. He only survived by fusing his cracking soul with his mechanical body, and has forgotten all that he was before he became the famed robot star. The Hunger has stripped him of all aspects of mercy, and he stalks the halls of the Core and his destroyed shrine of his beauty, haunting the corridors with loud, staticky regurgitations of his television show interspersed with insane laughter, weather reports, and old interviews/conversations.
Despite all this, he remembers what Burgerpants did to him, and would, given the opportunity, happily enact vengeance.
He is relatively harmless in his square form, only utilizing it to move, but once he has cornered prey, his back unfolds, revealing his ravaged, nearly destroyed EX form, little more than dismembered, sparking limbs held together with what remains of his magic. His EX form is deadly, strong beyond compare and, even in its state, nearly indestructible; he is merciless, and always hungry, and any monster that he catches is as good as dead, subjected to his television commentary as they are consumed alive.
Mettaton has many of the same foibles as he did before the Hunger. He is weak to praise, fashion, and daring posing, but these do not distract him from his starvation long. The best way to escape him, if you have the misfortune to find yourself in his presence, is to sing him Napstablook’s song. He will malfunction terribly, his machinery denying the memory but his soul crying out for his lost family, and he will retreat to regroup and attempt to calm his irritation. You had better run fast and hide well, though, because he will come back with a vengeance, and will not be able to be redirected again.
It is unknown whether or not his NEO form remains functional. Whether that's due to him not remembering how to activate it, or no one being able to escape him once he does, remains to be seen.
