Although the narrative that I had worked out with this PS 238 plotline was slightly different: I had the Crystal Skull pegged as a supervillain who had first infiltrated the casino in order to steal from it… only to discover that his organizational skills and mild megalomania were actually well-suited towards rocketing up the corporate ladder to head manager. And, of course, at that point he was in that sweet spot where the money was rolling in, the minions were bustling, the papers were avidly following every cackle and grandiose statement, and those cops and do-gooders could do nothing, NOTHING! MWHAWH-BAH-HAH-HAHH!!!!!
But having him just open the casino in the first place works, too.
PS: As you might have guessed, I’m a fan of the webcomic PS 238.
