Challenge. What's the most complex and unique superpower that could still be mimic by a Green Lantern construct?
Atom Even also count here. How versatile can construct creation be? Can construct creation be indistinguishable from a Rogue (X-Men) style power?
I ask this question. Because I have power system based in construct creation. Where the users have construct creation, probability manipulation, and also make portals that could travel trough time or different universes. These superhumans limited to objects, they become useless average humans without the objects. These superhumans are the Wizards of my superhero world.
