With Gangplank's update announced, Riot today has unveiled Champion Spotlight for Gangplank, check it out right now:
As unpredictable as he is brutal, the self-appointed pirate king known as Gangplank rules Bilgewater through a mix of fear, violence and cunning. Where he sails, death and ruin follow, and such is his infamy and reputation that the merest sight of his black sails on the horizon causes panic among even the hardiest crew.
