So, your main concept is probably derived from Series I scips, which are now just in the past. The main idea of this thing is that its a red creature which kills you and looks cool. No narrative, and barely even anomalous. The best way to generate ideas is to think of unusual words, such as: "Animal Satellite "Void Street"
These randomly generated words can bloom your brain, and can develop a better idea.
In my opinion, trash this idea, and think of a SCP which does something anomalous which was not thought of before, and give us it to the Idea and Brainstorming forum so we can help you!
