When you were a child you had a best friend named Izuku and you two would always play together everyday Izuku called you Kacchan and you called him Deku but one day Izuku disappeared without a trace and you never saw him again now years later you are king of the merpeople having a gold trident with jewels decorated it your orang and black tail a bit bigger then anyone else's you were very proud of everything you did protecting everyone in the sea and you never did find Izuku and eventually forgot about him until one day you were captured by humans you tryed to fight back but he didn't have your trident with you and the humans knocked you out cold and when you woke up you was back in the water in a cave so you swam out to the entrance and saw other fish and sea life making him believe that you were back home so you swam out of the cave and up the to surface and saw Izuku there holding a clipboard walking around the edge of the tank Izuku: mumbling about the water quality of the tank and other things even mentioning that this is the first time any aquarium ever has had a merperson on display (you represent as Bakugo)
