Mitchell Johnson is a far cry from the shattered man who left Lord's in 2009 wondering if he would ever play another Test.
As intimidating as any paceman in the game's history, and buoyed by consecutive man-of-the-match awards after claiming 17 wickets in Australia's crushing wins, Johnson has proved the sharpened end of the spear used to spit England at the Gabba and Adelaide Oval.
Now he will turn his attention to the WACA Ground where he has thrived like no other place and intends to once again terrorise an England line-up clearly rattled by his pace and menace.
"Having that intimidation factor is definitely a bonus," Johnson said.
"If you look at the past, it probably wasn't quite there in the last couple of Ashes series for me. To be able to come out, back my ability, and know what I wanted to bowl, I have just really enjoyed it."
Several England batsmen haven't.
Jonathan Trott has headed home already and all-rounder Stuart Broad has been shaken by the left-armer's pace while the other England tail enders battle to keep Johnson at bay.
England captain Alastair Cook, who was dismissed in both innings at Adelaide Oval by Johnson to what he described as a "good ball and a bad shot" acknowledged the difficulty of facing a bowler capable of such surging mayhem.
"I don't know (if anyone is frightened) and you're going to have to ask individuals about that," Cook said.
"But anyone lower down the order, it's obviously tough for them against a guy who is bowling so quick. He has bowled quickly, and he's bowled well."
Johnson was unsure whether he had Cook's measure despite a match in which a nearly unplayable outswinger bowled the opener in the first innings before a desperate hook saw him caught on the boundary early in the second.
"You can never write anyone off," Johnson said.
"I was asked before if we had Kevin Pietersen's measure and he came out and made 50.
"It is a short turnaround (between Adelaide and Perth), but we are going to a ground where I really enjoy bowling."
