Warrior cat names? Help pleaaaase!

So I'm going to write a warriors fanfic. I'm super super pumped about it, but I can't think of good names! My main characters shall be brother and sister. They are kittypets that find their way in to the wild, much like the first book with Rusty. Only problem, I CAN'T THINK OF NAMES!!! Now I'm pretty good at coming up with she-cat names, but I struggle immensely with Toms. So please help me! I can't thin of anything as good as Fireheart, I'm pretty sure that is the greatest warrior name on the planet! Anyways, help!!
