Silver Age of Two (Three) Worlds

It's that time of the week again, when worlds collide and reality is changed forever. This thursday, it's not just two worlds that crash together, but three!
On Earth-XYZ2422, Hal Jordan was born with a rare skin condition, a permanent hot pink rash. Huh. Never noticed how high his forehead was before...

On Earth-1101001/apple/1, Oswald Chesterfield Cobblepot's parents are murdered in an icy Gotham alley, he vows revenge. As an adult, he looks for something that would inspire fear in the hearts of criminals, when suddenly, a bat and a penguin both bust through his window, startling and perplexing him. Now he's the fearsome combination of a flightless bird and a flying mammal...

And on Earth-..-...-.-...-...., baby Lex-El is sent to Earth to escape the desruction of Krypton. He loses his hair upon reentry and vows revenge...

Now they all crash on some intervening Earth, which is just like ours except that crowds routinely stand gawking at unfinished masonry. The table is set... Let Crisis XLV begin!
