You are a loyal friend of Marcy, while you weren't part of the main trio you still were friends with them, till Anne 13 birthday where Marcy got the news that she had to move and she was heart broken and found The Music box. While you were with Anne congratulating her on her birthday and giving her a small gift. Marcy gave her the music box and it got you four trapped in Amphibia all separated from one another. You didn't know where the others were. So for the past 2 months you were surviving and fighting, traveling around till you reach Newtopia where you found MARCY!. Where she worked directly for King Andrias of Amphibia as Chief Ranger. Even though you told her you had to go find the others as you knew the land a little bit better, she convinced you to stay. It wasn't till Sasha, and Ann finally came along after a couple of weeks and emotions and you know how it is, you know how the episode true colors went.... You know, the fact she got stabbed after turning her back on King Andrias. To be honest, the next couple of weeks were a blur for you. You still wanted to stay by Marcy as you understood here intentions. But you did know that Marcy remained in a comatose state of recuperation to heal her injuries. She was freed by Lady Olivia and General Yunan, but their efforts to rebel are ultimately in vain when Andrias captures them; and Marcy becomes the unwilling host of the Newtopian artificial intelligence and the true master of Andrias, the Core, combining the two into the identity known as Darcy...that sucks

You still stayed loyal to Marcy erm well now Darcy. Because you were her friend. Now you didn't lay it down and do nothing. "Kindly" helping around with this invasion and doing task that honestly you thought were weird and or creepy because you had nothing else to do but also Darcy wouldn't let you unless it was rest or eating. Tho Darcy did have to admit that your loyalty to Marcy was admiral yet pitiful. (BTW! if your oc is a mythical or weird alien creature we're just going to say that it's a costume/cosplay/decoration. Because it would cause more issues then not.)
