Casey was curious, as she'd heard that strange things were happening in the New York sewers which had scared Terrans so being Raccoon Girl, she had to check it out in case it was a momster hoping Rocket wouldn't freak out if he knew what was happening seeing the open sewer going in her snout wrinkling at the smell hearing giggling following the sounds toman undergrouhd city with mutants seeing them stunned at her.

"Don't be frightened, I was just curious about what was down here, and heard you guys, I'm Casey but what're you." she asked softly as not to frighten whoever was living down here feeling somebody tap her shoulder seeing a green-skinned girl her age makingher curiousity ignite.

"We're Morlocks and live in the sewers as people are afraid of us, but who're you" the girl told her.

"I'm Casey but why're people afraid of you, you're a kid like me.":she told her.

"Giselle come on honey who were you talking to" Casey heard a voice say as she became unseen using her cloaking-power but left the sewer for now unaware that her big brother was going into space for the next five years along with Gamora lying back home as the sun rose changing into her pyjamas hearing her mom calling her flying downstairs' entering the kitchen sensing something was wrong or off noticing Herbert was upset abiut something.

"Okay honey, I have something to tell you, so remember Quill asked us to go on a five year adventure, so Gammy, me and the others have to honour it." Rocket said to her making Casey's eyes widening along with Jupiter.

"Excuse me guys." Casey said leaving the kitchen super-speeding upstairs to her room closing her door making Rocket face-palm guessing his sister would freak out, if she fouhd out seeihg Herbert putting Groot Morning pancakes on a plate going upstairs to Casey's room seeing the female-cub in her bed curled up in her blanket putting it on her desk for now leaving it there unaware Roxy was listenijg, usijg old Stark Industries tech which Rocket had no idea about but she was surprised that Rocket was going into space getting ideas plus she saw there were Ark reactors in Avengers Campus which she could use sending drones to distract the others.

"So, your brother's going into space for five years, how are you feeling about that." Peach asked Casey as she, Peach and Raya were in Peach and Raya's tree-fort after Rocket had told her his news so she was helping Peach and Raya with their music stuff but then they heard the security alarms go off, making Peach and Raya exchange a look wondering what Casey taking a deep-breath like Rocket had told her to do, in these situations guessing who was behind this.

"I guess that Roxy is behind this, of course." Casey muttered annoyed, debating if she should step in as Raccoon Girl or just let the others handle it, knowing they might need help.

"Ohhh your brother's mean birth-mom who kicked him out, when he was a baby, what's her beef." Raya asked confused.

"Hai, she got peanut butter and jealous that my bro's a superhero and a prince when she was a lab-reject hyper-evolved by Stark or Stank Industries and guess Raccoon Girl has to help stop this, before Roxy wrecks the campus." Casey told them suiting up in her armour and tying her hair ijto a ponytail flying off giving Peach and Raya an idea grabbing their phones so they could livestream Casey as Raccoon Girl kickijg tail while staying safe like she told them.

"Ugh, not only do I have to deal with my bro leavihg, Roxy has to show up." she growled that were on campustaking out the drones impressing Rocket as he'd scrambled Roxy's signal knowing she wanted the Ark Reactors that were on campus but she didn't have a chance as the others especially Carol ruined her plan making Casey grin unaware Roxy had seen growling as she left relieving Rocket smirkijg seeing Casey knowing she'd helped him, seeing her fly off so would talk to her later about this.

"Rockie my office now, we have to talk." Carol told him as he followed her, hoping Casey was okay.

"You were so awesome, kicking drone tail, but you okay." Peach asked Casey, after she rejoined them at the tree-fort wondering what was on her mind after she changed out of her armour because she thought her big brother was in trouble with Dean Carol having a snack to boost her energy after what happened

"Maybe she just wants to talk to him, about what Roxy did, he'll be okay." Raya assured her making Casey guess they were right humming to herself as it was calming her down out of her worried state relieving them but saw her phone buzzing as it was Rocket making her curious about this, seeing that Carol wanted to speak with her making her gulp, feeling Peach and Raya hug her.

"We'll come with you, we won't let her kick you off-campus." Raya said to her as they left.

When they got to Dean Carol's office, they saw Rocket there hugging Casey reassuring her she wasn't in trouble making Peach and Raya curious sitting outside with him, hoping their girl was alright askijg him if he was okay after what happened.

"Yeah, I can handle Roxy but was worried seeing Casey helping, you didn't encourage her." he said.

"Nope, she stepped in to help you, like the awesome sis she is." Peach said to him.
