Um if u guys like lore feel free to read if not Welp 😭😭

OK.

Marine & Merlin They're paired together since they're siblings. Merlin is the older brother of marine with him being 19 almost 20 and marine 17. They both are guards and enjoy what they do! They both always loved back line weapons with marine maining Chargers and Merlin stringers. When they were younger they decided to run away together away from home, they lived in a small town and eventually ran away to inkopolis square and lived their lives since, they ran away due to their parents. They felt as if they didn't want them anymore since they always said bad things behind their backs about them, their parents wouldn't physically abuse them but would mentally (?) abuse them by saying horrible things. So they just ran away lol. Merlin is very protective of marine since she's all he has left of family, marine cares a lot about Merlin but doesn't feel the need to always be protected by her brother. They are both more chill and laid back but Merlin being more laid back and introverted.

Cyro Oh Cyro the silly guy who loves music and to sing!! He's 17 and together with marine after they met when marine was on guard duty. She came across him whilst he was singing. He's not into fighting much but still mains blaster he likes being in the middle of fights when he does fight. He spends most of his time in splatsville and eventually Merlin and marine moved to splatsville since it was the more popular of the cities, he comes from a small town as well but moved to splatsville since he thought it would be fun and a good path for his life, he has very loving parents and his best friend still lives in that small town but eventually plans to move to hang out with Cyro, Cyro enjoys company but he just spends his days living his life

Coraline She comes from the octarian army and eventually escaped due to hearing the spicy calamari inkantation after agent 4 saved Callie from Dj Octavio, she never got to know her parents due to shortly after her birth her parents were called to fight for the underground due to an emergency, they ended up dying but saving the underground. Shortly after she escaped she met marine and became best friends with her, she really enjoys fashion and machinery, fashion the most out of both. She's a super energetic and positive person no matter what happens, unless you bring up her past.

Aquamarine She's a Kraken, she knew Merlin when he lived in the small town they were close friends from childhood but everyone always looked down on her due to being a kraken. She has a very short temper and lots of things get on her nerves. After a friend of merlin's basically insulted her infront of many she snapped back but everyone thought she was attacking and going to hurt everyone which caused her to run away from town, she eventually met an octoling which soon became her best friend, but she lost her friend to the octarian army and never got to see her again and all the anger and sadness she had bottled up she decided to let it out by doing the exact same thing the octarian army would do to the people who won't join. She would make goggles and put them on thousands of inklings and octolings and make them fight everyone and make everyone see that she's not a pathetic little kraken and wants people to respect who she is and make the octarian army and everyone pay for everything that had happened

Indigo He's just a chill octoling who was minding his Buisniss until aquamarine took him captive and put him under control with the goggles she made, aquamarine eventually noticed that he was a lot more powerful than he looks and he became the assistant of aquamarine and would fight in her place if needed, after an ancounter with marine and coraline they managed to get the goggles off him and save him and take him back, he knew a lot about aquamarine and all he plans and he would use it against her in the future, overtime he caught feelings for coraline he liked her positivity and energy. He just minds his business and is more quiet of the bunch, but he is not introverted.

V Acid squiiiid! He's just the smug leader of the acid squids! He has a super long tounge he can use to spit acid at people, he usually doesn't care unless you get on his bad side, splatsville saw him and saw harm so he decided to build a place that could hold the acid he and the acid squids produce, he would plan to flood any place that hurts him or his gang, but because of the amount of acid he was creating it caused him and his gang to dry out but he still held on to make sure people will learn why he's really alive

Dolphie is just the guy who leads you to turf wars and anarchy battles he's just the friendly face who greets everyone!! Despite being a kraken.

Punchie is just punchie lol she's just a silly jellyfish

You're right Henry how did u know
