When reading something, what ideas did you have based on established premises?
For example, when Pres. Luthor was still in office, there was a storyline about a 'false' Krypton, complete with population and Jor-El, created by Brainiac 13 in an elaborate revenge trap against the Man of Steel. After the storyline, this version of Krypton still existed.
This gave me an idea - Luthor could find this pocket dimension Krypton, and while sending teams to mine for ingredients for Kryptonite, kidnap some Kryptonians.
He would then have these people brainwashed and trained in a black-ops squad, each one with Superman-level powers.
That's one of mine. What ideas do/did you have?
