Does my manga character sound too much like lavi from d gray man?

He's not that much like Lavi, although, if you were to make his headband a darker colour, such as crimson or a dark orange. For his hair, have VERY strong highlights, because, even with the other colour headband, he still looks a lot like Lavi. Also, in the manga itself comment a lot on his hair (something like FMA and Ed's shortness...like that a little). Give him a catch phrases (if you truley wish) that sounds nothing like Lavi's (in case you didn't know, that's "Big Hammer, Little Hammer *Grow, Grow, grow!*)
