Leo is the captain of the Ravens, as well as a born leader. He is a musician, and can play multiple instruments, as well as sing. He even writes a song for Hayley in season 1. It's shown that Leo can be a coward, for example, when Hayley and him first kiss, he tries to ignore that it happened and not face his feelings, or when Aspen arrived and he struggled to tell her that he actually was in love with Hayley. Another example is when Marcus shows Leo that Ryan Woods, (Hayley's mother) is still alive and that she will come back to consciousness after the next earthquake, but only if he stops his team (Daniel, Hayley, Jackie, Max, Alex, Brooke) from preventing the earthquake. He attempts to convince the team that this is the best option, which led to them all arguing over which is more logical (Standing back or taking action).
