I saw many artist ( often japanese ) who think that Apollo was a delinquent... In my opinion I think he's adorable like that >8D

Considering the fact that his personality a little fearful I suppose that he didn't get a lot of motherly love... *give to Lamiroir a black look* And... this kind of lack often leads to hard childhood.
