There is a diverse array of characters throughout the entire series and this will be reflected in the casting. In the future Humankind won't change its behaviours and cultures however, their environment will change and it will be fascinating to discover what those behaviours will be as we progress through the known Solar System.
Aliens haven't yet been in touch so the only Monsters will be Humankind in the form of Space Pirates, Slavers and genetically advanced humanoids, the Gen-I's. There are also Cyborgs and Robots which have gone rogue.Â
