The seven year old last season rose through the chasing ranks, racing four times at Cheltenham placing in two smart events before going on to win another two.
One of those wins came at the festival in the 20 runner Listed Novices' Handicap Chase and the form line he holds has been franked by many horses throughout last season.
The superstar stepped up for his seasonal debut at Carlisle last week in the Colin Parker Memorial Intermediate Listed Chase up against some proven chasers.
However, the gelding showed massive improvement to land the event and his handler stepped up him up next time out to the Grade Two 1965 Chase at Ascot.
Imperial Aura is quickly becoming one of the most improved chasers throughout the season after going on to land the event with ease.
He heads back into in another Grade Two as favourite on Saturday and is odds on to keep his unbeaten run for the season going and on form looks tough to beat.
