Gandalf The Grey
“He wore a tall pointed grey hat, a long grey cloak, and a silver scarf. He had a long white beard and bushy eyebrows that stuck out beyond the brim of his hat”
Gandalf was the wisest of the Maiar and the most awesome wizard, like, ever. He is immortal, defeated a Balrog for 2 days and 2 nights on the peak of Zirak-Zigil (A Balrog is a corrupted Maiar, and it takes huge amount of power to destroy one), and single-handedly defeated all nine of the nazguls on weathertop by summoning fire and lightning for a FULL NIGHT! Awesome right! Like this threadless shirt, you shall not pass!
