She's the first girl to break my heart.
Terra first appeared in New Teen Titans 26.
She eventually joins the Titans in issue 30.
For two years she was a Titan. I always thought she would be the Kitty Pryde of the team....that despite the hints, foreshadowing and mini-reveals, the story would end differently.
It is tough to post much without spoiling. And the title of the story arc pretty much tells you all.
But these four issues turned my comic world upside down. This was pre-internet...pre-Wizard...there was no community of comic fans spoiling stories....I was lucky to find new issues in one of the two or three stores that carried comics on their spinner racks in town...
It turns out that Terra's joining the Titans and acting like a hero was all a ruse. The whole time she was working with the Titans' enemy, Deathstroke the Terminator, in order to betray and kill them.
The eventual reveal
And the inevitable...tragic ending...
