Good names?

So readers, I was just wondering if you thought that the name Jack suited that character. Before lil darlin' red over there decided she wanted David B. to be in the cast, and i obliged happily. Jack Power was supposed to be an invisible character, the hidden/ extra brother you never hear or see about. Remember the Cunnighmans (or however you spell it, i didn't really watch the show, BEfore my time, way before), the Ron Howard character had a brother, but did u ever see him. Nope, u surely didn't. Anyways, now that David B. is playing this character, I'm not quite sure the name Jack suites him at all. And I can't have him being called Angel, so please give suggestions on what the new name should be.

P.S.
One suggestion, it has to be shoutable. Like "STELLA, STELLA"
