Quote: Doc.Mid-Nite said: In JLA #122 Dr. Light uses an invention of his to discover the secret identities of the JLA, and is "mind-wiped" by Green Lantern (Hal Jordan) & in #154 Dr. Destiny learns the identities of the JLA and is "mind-wiped".
I think I mentioned before that Green Lantern gave Major Disaster a mental block preventing him from giving away the identity of Hal Jordan as GL, and which drove him insane. Following his reform, Disaster now is a member of the JLA (I'm not up to date with that, so maybe not) and knows their security systems.
So, he was a mind wipe victim who went mad and then silly like Dr Light (see Major Disaster in the Injustice Gang / JLAntarctica) a former Silver Age foe of Green Lantern (which might explain why the Spectre cannot intervene in this), and knows how to bypass JLA security.
