So, Imagine The next Tier of GC rocketry takes you to the moons of Jupiter. what kind of boss would there be? Are we just going to have an Io dungeon, Europa dungeon, etc? I have a better idea. In GC5, you would have to combat several variants of evolved creatures; A fire-themed creature on Io, An Ice/aquatic-themed creature on Europa, A rock-themed creature on Ganymede, And Callisto.... Idk man, Callisto is boring. Anyway, these fellas would spawn intermingled with the normal evolved mobs, and have a one-in-59 change of dropping some kind of artifact. Then, once you have all the artifacts, You can summon the final boss with a multiblock a la wither. This creature would've called... The Jovian Juggernaut. Tell me what you guys think.
