venom
"hey kid?" tony yelled from the living room of the compound. "can you bring me my water? i left it on the counter in the kitchen."
he heard the shuffling of his teenage kid gradually getting water until there was a glass in front of his face. "thank you."
a muffled "mhm" came from behind him. he rolled his eyes before taking the glass from their outstretched arm.
"why don't you come sit down dude? hang out with us. drax and rocket are here." he grabbed their wrist before they could retract it from over his head. "cause some chaos like you always do."
(Y/N) made their way around the couch, flashing tony a slit-mouthed grin. "anytime." they snorted, before noting the reaction of the avengers around them. "what?"
pietro pointed at them. "your mouth just..opened?? like.. all the way?" the sokovian stared at them, heavily confused. "i do not understand? how you do that?"
"do...what?" they asked, voice lilting in a way which meant they were trying not to laugh.
pietro raised his hands to his face and mimicked opening his mouth all the way to his ears. "how do you open mouth that wide? it is scary!"
(Y/N) locked eyes with wanda and lost it. they were both laughing so hard wanda snorted, which sent the both of them into another fit of laughter. once (Y/N) had managed to calm down, they took a couple deep breaths and spoke. "i am infected with the venom symbiote. it basically means i have an alien living with me. in me. i'm like the host body. but we're pretty good friends, and i've learned how to control it so i can alter parts of my body. the mouth thing is just pretty common. i thought you guys knew, but i guess not."
"can you do it again??" rocket asked, leaning forward. "that was sick."
they grinned, mouth tearing at the corners of their cheshire smile. their once perfect teeth morphed into a spiky mess, and their tongue elongated until it looked like it would no longer fit their mouth. they glared into his literal soul, pleased to see the fear and respect they deserved residing there. "happy?" they growled, tongue flicking over their ultra sharp teeth.
rocket and drax were staring, ironically open-mouthed. "do you have ANY IDEA how cool that is?" rocket exclaimed.
their face shifted back to its normal state before they spoke. “yeah. it’s like my specialty.”
“second question. i’ve got some people i’d like to impress on Xandar. wanna come?” rocket looked at the teen hopefully, waiting on their answer with bated breath.
“fuck yeah.”
