Teela's characterization had been one of the especially low aspects of this new DC ongoing series (constantly complaining about things, getting angry over small details, berating her fellow Masters), so it might be for the best that old Teela has passed away from the continuity. Granted, however, I thought that Abnett had done a considerably better job writing Teela than Giffen had. Maybe that crossover with the DC Universe humbled her a bit?
Agreed, any evolution away from the "bitter Teela" will be a great improvement. I'm quite curious to see where it all goes from here. They've survived their adventure into the depths of Eternia, now they have the Horde to deal with up top!
The Horde may be out there, but now they have an army of snakemen to help them out!
I wonder if there's a good in-universe explanation for why Teela was so bitter and mean in early issues (outside of bad writing). Perhaps... the pain of being "betrayed" by Orko coupled with the ongoing frustration of not knowing her mother might have pushed her into a dark place?
