How would Cryptid Eclipse suddenly found their Y/N turned into a 'Mothman' (somehow. Maybe like werewolf situation but Mothman)?
Oh, this is fascinating! Perhaps the little hunter received a bite or scratch, a small injury that they've received dozens of times before and watched heal and turn into a scar, and maybe there's a symptom or two but they brush it aside despite their sweetie's complaint. It's nothing that they don't make a tiny note of in their book. Y/N researched beforehand about the potential of the cryptid infecting a human and transforming them into something monstrous, but it's not a werewolf, so there's no need to worry. It'll heal. They're a little feverish but it'll pass. Don't worry, sweetie.
It could be very scary at first. If Eclipse, say, after returning from a little midnight hearty snack, finds a mothman creature in Y/N's bed where their little hunter just was, red glowing eyes round and staring back, Eclipse is going to attack.
Eclipse is furious and blinded by rage and panic for Y/N but strangely, the creature flapping and thrashing over the quilts has the same heartbeat as their little hunter. They keep squawking at Eclipse, calling them by name. The cryptid looks terrified and bewildered, too. It just doesn't make sense until Eclipse stops attacking long enough to hear the beast cry out "Sweetie, it's me!"
Then Eclipse stop, their claws around the fluff of their throat, and ask "Heart?"
Eclipse helps them sit up and stare at them, their body covered in tiny pine green and cream colored scales and their wings are large and angled, decorated in great patterns of mud brown with piercing green eyespots.
You're still their heart, freaking out and trying to make your wings stop knocking into the walls of the airstream while simultaneously trying to grab your book to jot everything down. Eclipse decides they can make one except for the mothman creature they so despise—because it's you.
