Razorwhips are reclusive by choice, due to extreme mistrust of both humans and dragons. However, those who are able to prove their worthiness to a Razorwhip will have made a powerful friend and ally for life.
Speed and Agility
Razorwhips have been shown to be quite acrobatic dragons as their metal-like bodies have no lack of flexibility at all. They are able to twist their neck and their tail as well. They can also tie themselves into a knot, according to Bucket.
It was shown from Windshear that Razorwhip speed are fast enough to be near as Night Fury.
Strength and Combat
The Razorwhip has shown to be able to pull a tree off the ground quickly, and drag it in the air at full speed without any struggle. They were described to be as powerful as a Typhoomerang, as Windshear fought one. But it is unknown who had won, and Windshear was badly wounded. It is described to be as strong as a Typhoomerang meaning they could lift possible amount the weight that Torch has done in the past.
Razorwhip from the Dragon Arena was shown to be able to fight against Toothless the Night Fury as it was able to leave scratch on the foot fast enough before Toothless could react to dodge but soon was defeated in short battle from intelligent battler.
The Razorwhip has a telescopic tail that it can use as a whip. and can even be used to grip objects. This tail is also
extremely sharp, seen to be able to cut wood and rock. The rest of their body is quite flexible. The Dragon Eye indicates that a Razorwhip can use its tail to squeeze the life out of its victim.
Like Deadly Nadders and Whispering Deaths, Razorwhips can shoot spines from their tails. They are incredibly sharp
and can pierce through wood with utmost ease. The sharp barbs are compared to that of a Speed Stinger's by Fishlegs.
The Razorwhip's breath can burn the flesh off a human from a hundred feet away. The intense heat of the Razorwhip's
fire can be shown from its bright blue color. However, it might have been an exaggeration from the Dragon Eye, because the twins, Snotlout and Barf and Belch were able to survive at very close impact.
Razorwhips have extremely poisonous tears.
Endurance and Stamina
As it was shown that Razorwhip is able to take the attacks from Typhoomerang but can take serious damage from large opponent according to Heather as her dragon Windshear has proven needed to be treatment of care to heal. As for Razorwhip like Windshear took amount of pain from Shattermaster the Gronckle under the belly as a sign of weakness to Razorwhip.
Razorwhip has amazing stamina as it able to travel high speed long distance as it was being chased by Night Fury like Toothless and able to still travel.
It is also shown to be highly intelligent, distracting Hiccup before hurling a tree towards them.
The only vulnerability of the Razorwhip is its propensity to eat sea slugs and it seems that the belly of Razorwhip can be weak spot as proven by Dagur Shattermaster have done that makes Razorwhip drop down to the ground to be stun for short period of time.
