This is splatoon 3 concept art. Introducing the Rayling (left) and sharkling (right)'s "squid" forms! both are very much different from the squids and octolings, although they do swim in ink. Let's move on to some lore Raylings- honestly, not my idea, but I will explain what I know. Raylings are more of a group or army than a species. They take control around the area, and is more of dictating force. Assuming that not all raylings are evil though. They have their base and futuristic technologies. But this "evil" force is more so the rayling society. The Emperor rayling has control over a huge army, and probably doesn't tolerate traitors either. Seems as though there are groups moving in to protest or fight back... Sharklings- These species are actually the former residents of the broken villages is salmon run. They were known to be peaceful islanders until... well, the salmonoids struck. At first it was a mess. Not many survived. So the remaining sharklings did the one things they could do. Try and take or use the salmonoid technology. Throughout the years, the sharklings fought back against the salmonoids, slowly modifying the weapons to fend against the salmon better. But in some point in time, the great mothership struck: a huge mothership that carries around ten normal motherships. With very few numbers, the sharklings didn't stand a chance. Not to forget, but the islands have also mysteriously sunk into the ocean slowly every year, and at this point there wasn't much land left (as seen in splatoon 2). The battle didn't last long, and the salmonoids dominated the field surrounded by water. Soon enough, the sharklings had no choice but to get on a boat and sail off into wherever else. They finally reached the main islands including inkpolis and many other areas, but the majority of the sharklings ended up in the place where is not called the "Inknation". The background is a small sneak peak, or more of a concept art for a new stage. It is called "the gates of the ray base" Both teams spawn on the opposite side of the gate, and to get onto each other's side, they have to pass through the gate. The gate serves as an easy to defend choke point. Again, this is only a small idea therefore the stage is not so important and has nothing to do with the story.
This is concept art for the idea of splatoon 3! please read the instructions for a detailed explanation of the new weapons and characters. What should I draw next? please tell me in the comments. visit the splatoon 3 studio if you want to think of ideas too!- https://scratch.mit.edu/studios/26168612/ splatoon dubstep- https://www.youtube.com/watch?v=wbYM2Ax3gS8
