It depends on which Lara-Su you are interested in as there have been two. The first one is already profiled in the Encyclopedia, which will answer those questions. If you mean the version seen in M:25YL: 1) Sonic #131, 2) No, 3) 16. --True Red
whats the name of the comic where lara-su appears? does she have any brothers or sisters? whats her age?
