Well, as soon as Red X spoke, I thought, "Hey, I think that's Robin." When he mentioned a partnership, I knew it was him.
Okay, that's not my complaint. What bothered me is all of Red X's powers. He now has a glove that can shoot, well, all sorts of things. Also, some of X's disappearing can be chalked up to him being a hologram, but other times, he's clearing physically fighting the Titans before vanishing, meaning he can turn invisible.
I think it goes without saying that Robin won't be using the glove or invisiblity tricks ever again. True, Slade would probably have a way of getting around those things, but other villains won't. Heck, every time you need to sneak around, you'd be using that invisibility thing.
I know, it's just a cartoon and I shouldn't think about such things to much. But, when you show a character using a cool superpower, you have to wonder why they don't ever use it again.
It reminds me of an article in Comic Buyers Guide years ago. It was a review of an old silver age Superman comic. It was all about Jimmy Olsen getting zapped by a growth ray and Supes has to use the shrink ray that Brainiac used to shrink the Bottled City of Kandor. At the end of the story, Supes either smashes the growth ray or stores it away or something, leading the writer to ask why he didn't use the growth ray to restore Kandor to its original size.
It's the same thing here. I know we'll be seeing stories where turning invisible or shooting some kind of adhesive will be necessary, but everyone will forget that Robin can do that.
