Releasing the ball roughly in line with the umpire's chest, and at sharp pace, it is devilishly hard to pick up - even after years of perusing film of his action. Throw in his clever slower ball and the job gets even tougher.
His numbers tell part of the story: 177 ODIs, for 271 wickets at 27.1. Against New Zealand, it's 29 wickets in 21 games at 23.8 apiece.
Sure, Malinga, with his distinctive yellow-tinted mop of hair and jewellery in ears and eyebrows, has been collared at times.
But it's in the dying overs, as batsmen are looking for victory, trying to manufacture runs at a time when they might prefer to focus on survival, that the threat is writ large.
The list of batsmen fooled by fast in-ducking yorkers or half-paced, dipping full tosses from his odd trajectory is long and illustrious. There's no shame in having been Malinga'd.
One point in New Zealand's favour: the 30-year-old from Galle is seriously underdone after being sidelined by an ankle injury, and subsequent surgery, since the end of August.
It may be that the teams who have more to worry about are the likes of England (March 1) and Australia (March 18), who will face Sri Lanka and Malinga later in the Cup, when he's got his game in full swing.
Still, there's no doubt the balance between the teams - after New Zealand's convincing recent 4-2 series win - will have shifted on the back of Malinga's return.
