Pain

Pain was a sensitive child, prone to crying over the sufferings of himself and others. However during time he realized, that his sensitivity was actually a strength, as it allowed him to understand pain better and, in turn, be kinder to others. He spent his entire life placing the needs of others before his own.
Thought he looks fragile and weak to the untrained eye, he helds a great amount of power and is even called a god among some Dragons. Hearing this often enough, Pain, too, started to regard himself as a deiety and made his life goal to bring peace to the world and eliminate all pain and suffering.
