In the books
In the A Song of Ice and Fire novels, Viserys II was the second son of Rhaenyra Targaryen and the younger brother of King Aegon III, the Dragonbane. He served as Hand of the King to both his nephews, Daeron I, the Young Dragon, and Baelor I, the Blessed, helping keep the realm intact first while Daeron warred and then as Baelor prayed. It was rumored that he had the stonemason Baelor had appointed as High Septon poisoned. It was also rumored that he poisoned Baelor, which is the reason he's not remembered fondly. He officially reigned only for a year, but he truly ruled and preserved the land for much longer as Hand of the King, keeping the realm together while Daeron obsessed with fruitless conquests and Baelor obsessed with prayer.
According to a semi-canon source, Viserys II was clean-shaven with long hair. He had a prominent nose, bushy eyebrows and a shrewd, calculating look to him. He wore the simple crown of Aegon III.
