when every I read about Albus talking about beating the leader of the light, I always imagine him puffing up like a chicken
But there was a hitch in his plans, Dark Lord Magneto. Oh... Albus very well knew that Magneto was in no way a Dark Lord but it can't be helped. After all, Magneto actively worked to ruin his plans and whoever ruined his plans must be a dark wizard after all he was the leader of light.
