Suicune's life before the fire was a troubled one using the obsession to find an 'untainted' water source as the excuse to travel. After the fire, even more so.
His journey takes him far and wide across several regions when he encounters one particular water source that sends the Pokemon into a world vastly different than his own. A world without Pokemon or humans, and founded on the concept of kindness and love.
With nothing to return to, Suicune decides to stay, and explore everything this world has to offer. His long life ensures the seas and oceans are his domain, but its never enough for the free spirit. His explorations never satisfy him until he discovers something he had been missing all long, and desperately needed.
The ability love again, and perhaps forgive.
