We open up with the usual Jor-El is telling the Council about Krypton's up-coming end. Instead of the usual, Jor-El (and the readers of Earth-Thinker) got a suprize, the masked Science Controller--"The Main Brain of the Science Council", argees with Jor-El, with out any solid proof. They is a little clues--the other members joked that Jor-El is having affair with the Science Controller, but Science Controller tells her saying "her word is law--and one against her law might up in the Phantom Zone." Jor-El is offer a ride to her house.
We learn that Science Controller--to prevent bad Kryptonians, were mask to prevent trouble. In Science Controller's car, she removes her mask, revealing a 15-year female genius from Argo City, Kara Zor-El, Jor-El's neice.
I don't think I like this version of Kara. Zoning people for questioning her dictates (or even for gossiping about her) isn't something a respectable leader would do.
Your intention is probably that we should like and trust this character because she's based on a character whom we already like and trust. It doesn't work, because your version of Kara doesn't act like the Kara we know.
Of course, Kara gets a call from the Council, Lt. Lesla-Zod, a Council member forces the 'Science Brain Affair Rule' on them. Zod stated that only one male and one female can leave Krypton--between the ages of two and seventeen.
...except on Thursdays and alternate Sundays, but not when there's an "R" in the month.
No, really, that rule is incredibly contrived. How would they justify having a rule like that? Besides, I thought Kara's word was law. If she doesn't like this rule, why doesn't she just tell them to change it?
Durning a space trip into a far planet in far corner of the galaxy, the Kent die of a old age--but are replied by similar people.
Since when do the Kents take space trips?
When Superman hits age 25, a Kryptonian rocket enters Metroplis during a charity event. Inside is blonde hair Kryptonian, named Kara Zor-El. Kara Zor-El now is disappointed again--she had another reason beside her genuis--her new found super-power. Kal-El has a idea for her--but first he need to some checking. Kal-El takes her to his friend, Bruce "Batman" Wayne's Bat-Cave, where Bruce tries to X-ray her--but fails. [In my universe, X-ray can't work on Krypton--even with the new 'Control Break' power-] Kal-El wanted to make sure she was a human faking super-powers. Kara is give to the Danvers, who give her the name of Linda Lee. Of course, being normal human drives Kara batty--so Kara expects a offer from Kal-El, to become Supergirl, his partner. Kara arqees with that.
Ooooookay, you pretty much lost me here. Kara is disappointed because she's lost her powers? How did this happen? Wouldn't that remove her inability to be X-rayed as well? And why bother going to the Batcave? He could use his X-Ray vision, or just borrow a machine at a hospital. Finally, how can Kara possibly be Supergirl if she doesn't have powers?
So what do you think of Earth-Thinker?
The concept needs work, and you desperately need a good copy editor.
