What was the nickname of Sir Henry Percy, the English nobleman who lead rebellion against Henry IV?

Sir Henry Percy (20 May 1364 – 21 July 1403), nicknamed Hotspur, was an English knight who fought in several campaigns against the Scots in the northern border and against the French during the Hundred Years' War. The nickname "Hotspur" was given to him by the Scots as a tribute to his speed in advance and readiness to attack. The heir to a leading noble family in northern England, Hotspur was one of the earliest and prime movers behind the deposition of King Richard II in favour of Henry Bolingbroke in 1399. He later fell out with the new regime and rebelled, being slain at the Battle of Shrewsbury in 1403 at the height of his fame.

Percy and members of his family had many grievances with Henry IV (the new regime). They rebelled in the summer of 1403 and took up arms against the king. Percy marched to Shrewsbury, where he intended to do battle against a force there under the command of the Prince of Wales. The army of his father, however, was slow to move south and it was without the assistance of his father that Henry Percy and Worcester arrived at Shrewsbury on 21 July 1403, where they encountered the king with a large army. The ensuing Battle of Shrewsbury was fierce, with heavy casualties on both sides but, when Henry Percy himself was struck down and killed, his own forces fled.
