As another reviewer already mentioned, your character has a lot of Mary Sue-esque traits. You've probably heard the term thrown around before, and I'm not sure if you know what it means, but, basically, it is a loose term used to refer to characters who are unrealistic.

Of course, a writer wants their original character to be likable. After all, who would want to read a story centered around a character they hate? It's only natural that a writer, trying to create a likable character, inserts any traits he or she deems desirable into the character. Often, this includes beyond beautiful looks, powerful abilities, personality traits the author likes, good relationships (or even romance) with characters the author likes, bad relationships with characters the author hates, etc. What results ends up being an overly perfect, unrelatable character, and what often follows are canon characters acting completely out of character.

What I am seeing here is this Haley character wandering into the Titans Tower and instantly winning Robin's heart and, seemingly, Cyborg and Beast Boy's friendships. When an original character walks right in and instantly charms a normally stoic character simply by being beautiful, that's a major red flag. And, from what you've implied, she's going to become close to Raven. While there's nothing saying that Raven can't become close friends with an OC, one must consider that Raven is the type that one must get to know for a while. Oftentimes, writers handle this poorly and have her instantly take a liking to a character for no apparent reason.

This isn't to say that your character can't have any likable traits. What she does need is some actual flaws; ones that can be relatable and create conflict. I'm not talking tragic flaws (unless you want the story to be tragic), I'm more talking about flaws that make sense for her personality type. As a hypothetical example, say you want Haley to be a funny, friendly, playful character. Worded that way, it seems like a likable personality. However, personalities have their downsides. Sometimes, playful characters clash with the more serious personality types. Also, friendly characters may, at times, be viewed as overly friendly, naive, or eager-to-please. Having some of the less likable parts of her nature come into play will help make her more realistic, and likely even more endearing to readers.

Don't feel like you're a bad writer. Heck, your grammar is some of the better I've seen on this site. I like your power concept, too. It isn't often that I see female original characters with technology-related powers, and from what I've seen so far, it seems relatively well-balanced. Again, accidentally creating a Mary Sue-like character is common, and can be fixed with practice.

Feel free to PM me if you have any further questions. :)

WAY ooc you need to make sure that they stay in character. First off they wouldn't let her into the tower, cyborg and beast boy would be louder, Raven isn't always meditating, Robun wouldn't let her touch his communicater AND they would be more careful after Terra. It's a good idea BUT you need to work on it ! Before I forget,you might want to elaborate on Starfire's mission and her relationship with Robin. BE VERY CAREFUL!Your. Really close to making a Mary-Sue
