Ok, againts all of Jax feats:
https://vsbattles.com/vsbattles/3681590#136
1. Fugil started using Drag-Knights at age 14 making him the youngest Drag-Knight at the time. He self-taught how to use a Drag-Ride and with that a Divine Drag-Ride, also mastering multiple weapons like swords, daggers, etc. At that age he became the most skilled Drag-Knight and keep training to make him better, take into account that basically everyone he fought were in constant war with decades of experience. He also made his Hidden Techniques from scratch. Also, take into account that Fugil now has over 1000 years of battle experience. Fugil can hit a lot of pressure points without killing his opponent while using Violent Strike.
2. Fugil is also extremely analitical he can see weakpoints despite not seeing his opponents. He attacked Singlen despite the fact he couldn't see him and reacted to his attacks despite being frozen. Fugil's senses are better than Lux's and Lux can do that, Lux did it againts Yoruka, she has such stealth mastery that not even people who can detect invisibles can detect her, and yet Lux can.
3. Fugil masters every type of weapon swords, daggers, lances, pistols, cannons, even non-conventional things like anchors at the instance he enters a new Drag-Ride (if he didn't mastered from before). Fugil was capable of using Typhon to fight physically againts the Paladins, and one of them was a master martial artist that trained Philuffy (the original owner of Typhon) and still was more skilled than her.
4. I don't know how can you use magic by sheer skill (since that doesn't make sense), but eh. Fugil fought againts the greatest Drag-Knights in existence at the same time, he defeated them while treating them like nothing. At the very instant of the battle Fugil alredy had Greifer's weakness and used it againts him.
5. That's just good hearing, and Fugil literally found Singlen's mist's weakness the very instant he activated it.
6. That's what Chaos Brand is, a blade larger than Fugil, he can still wield it. Fugil's skill was so great that he was deemed as the perfect Drag-Knight and the XFer gave him Ouroboros because of that. Fugil in base can already defeat one of the Seven Dragon Paladins, blocking a blow of a Divine Drag-Rid deespite the difference in mass and strenghts and he defeated her.
7. Fugil's blade skills allowed him to fight againts the six most skilled Drag-Knights of their countries at the same time and he is basically the most skilled Drag-Knight in the world. Fugil literally killed people after going out of a cryonegisation, Fugil is also extremely skilled with basically every weapon since Drag-Rides have different weapons and some of them have multiple of them, and not only that, he is also extremely skilled with things like anchors. Fugil turned down the enviroment created by Singlen, Singlen created mist and rain that blocked Fugil's vision and being capable of comprenhed Fugil's movement and position, Fugil still countered that by slowing down the rain completely misdirecting Singlen, and he was capable of doing that in the instant Singlen activated the technique, and Fugil battle style adapts to the battle style that adapts to his own.
8. Fugil already defeated the best armies in the world and the best group of Drag-Knights of the world, the Seven Dragon Paladins and Aeril.
9. Fugil masters every type of Drag-Ride in the planet, including Divine Drag-Rides when only mastering one type of Divine Drag-Ride requires extraordinary stamina, mental strength, and skill. And he outskills Mishis who knows how to counter every Drag-Ride in existence.
10. Fugil outmatched Singlen who is superior in skill to Mishis.
11. Fugil dodged and attacked while his vision was completely blocked by a thick mist and his opponent could predict his movements. And he should be more skilled than Lux throwing things like Daggers, since Fugil is Lux 2.0.
12. Only mastering one type of Divine Drag-Ride requires extraordinary stamina, mental strength, and skill; and Fugil masters them all. That's literally his battle style, just that he can find openings or weaknesses without actually seeing the person like he did with againts Greifer's Invulnerability and Singlen's mist.
13. Fugil literally casually outskilled Mishis, who he praised by almost touching him, and also outskilled the Seven Dragon Paladins, which he recognized as the most skilled opponents he ever faced with little difficulty. Fugil mastered the use of a Divine Drag-Ride at age 14 when he started wielding Drag-Rides at... age 14, and outskilled every Drag-Knight there was.
