Type: Transformation (in an imaginary story)
OR the truth may be that Anakronus is a nutjob in a Centurion outfit from a costume shop, wielding a blinged-up .45 automatic. At least, that's what it looks like when the Atom, Elongated Man and Red Tornado show up to save Snapper and his family. Which doesn't explain how Anakronus knew about the Lord of Time or why his gun makes sci-fi noises. I call shenanigans on Len Wein, and to no-win a no-prize, I'll say Anakronus' story is true, but the JLA prevented the timeline from occurring somehow, leaving the poor villain lost in time, his mind broken, with echoes of memories of what once went wrong.
Section for Snapper Carr haters: Instead of using his JLA signal device (he doesn't think of it), he calls the telethon and puts subtle emphasis on certain words to let Green Lantern know he was in trouble. Being subtle with Hal Jordan is a risk, I think you'll agree.
