He doesn't have any form(s) yet as he is too young unlike his mother-like sister, Shara. His tail is his pet 'soul'.He is the popular one out of their family.Shara's and Null's parents are dead but often(always) saw as spirits, helping with life.He is an Emo yet wants to be a Timechanger founder.Sadly, Shara will take that place once she is 20, so Null slightly wants to kill her so he takes her place.He doesn't have an age but you can tell by saying young or old.
