When i was in middle school, I remember drawing some ideas for Paul an his friends (back then he used to be a weeb kid with a katana and had a sidekick magical friend who was based on Anime Chica from FNIA) in a more steampunk setting.
What you see here is a weapon that was designed to be the main villains ultimate weapon of mass destruction, which was based on the non steampunk villains true form, which was a sky covering blob of dark matter with eyes, tentacles and mouths all over him, but the steampunk one is just a machine that breaths fire and flys with usage of three ballons, with two being filled with smoke.
That's all, its just something I came up with when I was a middle schooler.
