[@onenote] For example. You could change telepathy to full on psychic which has telepathy anyway.

And if you've seen Naruto, then sire intangibility is a good power but I recommend that you do what Tobi does. It has no time limit however he is vulnerable when the power stops working. For example, he uses it, it finishes and then is immediately attacked from the back. It makes him quite powerful but can still be beaten. Another things is if someone makes something explode inside of him at the precise moment he's using it. The explosion would still get him, as with any other attack.

Basically, he is vulnerable just as he's activities the power and just as it finishes.
