I think the idea that Terry's DNA was manipulated before he was even born to make him more like Bruce only takes away from the character. It adds nothing.

If you want to think of it as such, he was already a "hero of fate." It doesn't help to know that half of him is Bruce Wayne, especially when the character was built on the idea that he was supposed to be so different from his predecessor.

And Pariah is right, it wasn't much of a JLU episode. I've seen more JLU involvement in thirty minutes of Batman Beyond. It would have fit better as the final BB episode.

I'm complaining but the storytelling is great, the best I've seen on JLU really. It's just that the story itself needed work.
