First I will establish some facts:
X Drake also known as the “Red Flag”, is a former Marine rear admiral who later turned pirate and the captain of the Drake Pirates. He wields a sword which looks like a rapier and was seen using it with a four bladed axe. He has been seen to have the sword in his left hand and the axe in his right.
X Drake possesses what is referred to as a “rare, Ancient Zoan Devil Fruit”, giving him the ability to transform into a theropoda dinosaur.
In this form he is large and powerful enough to directly wound one of the Pacifista troops by biting it in the head, something that is quite difficult due to the cyborg’s heavy armor.
X Drake’s Potential:
There is a likelihood that Ancient Zoan devil fruits may contribute in an individual having high endurance and stamina compared to normal Zoans. We know for a fact that the T-Rex had tough skin and heavy bones. It could sense prey using their body heats jut like infrared.
X Drake’s dinosaur transformation can also be classified as carnivorous. It is mentioned that the more carnivorous a Zoan fruit is, the fiercer the combat abilities gained from eating it, which suggests that Drake’s Devil Fruit makes him a strong and formidable opponent.
With the above stated facts, let’s imagine a battle scenario. With what we witnessed in Sabaody Archipelago, X Drake is a close combat fighter.
An opponent for X Drake will have to watch out attacks from the two weapons that he wields. I believe that X Drake uses those two weapons during his base form and hybrid form.
X Drake probably uses the two weapons in base form when he is testing out an opponent, like the way Luffy uses base form, Gear 2 and Gear 3 to test and if they don’t work he uses Gear 4.
When X Drake uses the weapons in his hybrid form it’s probably when he is going all out, I doubt he would go all out in his beast form since it’s huge and cumbersome to dodge attacks in that state.
Furthermore, X Drake as former marine may have knowledge and experience of the 6 powers “Rokushiki”. Now imagine this:
-A Dinosaur doing Soru;
-Full Shigan using Dinosaur claws;
-Tekkai in his Dinosaur form;
-Shigan with his tail;
-Rankyaku using his massive Dinosaur Hide legs;
-Rankyaku using his tail;
-Biting an opponent with those huge canines and powerful jaws.
Then imagine all above attacks using Armament Haki. Can you imagine how destructive this guy can be? Imagine his huge canines with armament haki or Tekkai plus full body armament!
