Re: Why did Zedd and Rita abandon Thrax?
 

I think the idea Rita and Zedd had an earlier relationship that led to Thrax. Rita just must have fallen out of favor at some point.

It did seem lime Thrax was forgotten. It was probably part of his motivation, even if he didn't want to admit it.

Re: Why did Zedd and Rita abandon Thrax?
 

They got separated after the Z Wave. Maybe Zedd and Rita tried to reform Thrax and he refused to listen.

Thrax was created from the evil energy that was purified from Zedd and Rita. Somehow some of it survived and reconfigured into Thrax. Rita and Zedd didn't know about him .

Re: Why did Zedd and Rita abandon Thrax?
 

Its likely the evil energy couldn't just be destroyed so it had to go somewhere. The creation of Thrax was one of the side effects of this. Ironically Thrax is as much Zordon's son as Zedd and Rita's.

Thrax wasn't exactly a cute baby.

Re: Why did Zedd and Rita abandon Thrax?
 

We don't know that..Maybe he let himself go.

Sounds like Thrax lost contact with them after Space.

Maybe Thrax went back in time to try and change history so the UAE never lost. And where his parents became all powerful. But Sentinel Knight ruined his plans.

I wish Thrax stuck around and united the villains into one powerful faction for the rest of the season.
