Thornton was unveiled as the new man in charge of the current Elite League Champions on Monday night.
He previously led the Giants for two seasons - winning both the British Knock Out Cup and the Challenge Cup in 2009 then followed up with a Playoff Championship the following season in 2010.
Thornton originally came to Belfast for the second half of the 2002-03 season as a player and the final piece of the puzzle for a team that eventually went on to win the first Playoff Title in franchise history.
