Strictly Hand to Hand

Takes place here

Giyera.

@jsdoctor Thoughts?

Giyera based on scaling and implication

@angeljax: His feat against May is still one of the best performances I've seen a regular human accomplish against her.

Dig should take this comfortably unless Giyera can use TK.

@the_magister: Good matchup, could be convinced either way though leaning towards Diggle. (I'm assuming Giyera is depowered as he otherwise stomps.)

Giyera's only relevant depowered showing is his fight against May - he briefly fought Bobbi in cqc, but often resorted to his powers and was KO'd when Hunter surprised him. The cqc portion of the fight was very brief. His May fight is a much better indication of his general standing as a fighter, and it's an impressive showing. When he fought H2H she was able to overwhelm him, but his flips and agility allowed him to get the upper hand on her a few times, so the setting specified in the OP definitely plays to his strengths in that regard. His skill level in a more typical fight, however, isn't close to May's level. She dominated him whenever he stopped abusing his agility.

Whilst he's often joked about on CV, Diggle's showings are actually much more impressive than many people give him credit for. His stats are well known and generally respected - he's been able to pin Oliver (who's stats are very impressive in their own right); tank a grenade point blank; practically no-sell blows from Ravager on Mirakuru; support the weight of himself, Oliver and Felicity with one arm; and no-sell falling 10-20 floors then being launched 30 feet by a canary cry into a car. His stats are practically superhuman, and the pinnacle for 'peak humans' in the CW or MCU. Speed-wise I don't remember him ever actually arrow-timing, but his reactions are excellent anyway. His aim-dodging is high-end, to the point where I've seen some people argue for this justifying him being a bullet-timer (though I personally wouldn't go that far.)

But people generally respect his stats . It's his skill that is often overlooked, probably because he rarely fights named combatants and most of his showings are against fodder. When he does fight named combatants, however, he performs very well. He performs to a much higher level mainly in later seasons due to his training from Oliver, though even in season 1 he could disarm China White and briefly stand up to her in H2H. Even just a season later he was a challenge for her, if not yet on her level. But skip forward another season and he's contesting with Al Sa-him for an extended period of time. Admittedly in a sword fight, though that arguably makes the showing more impressive as Diggle has little to no training with one. This is evident as, on the occasions when he does use a sword, he still often goes for his standard H2H manoeuvres.

It's once he becomes Spartan in seasons 4-6 that his skill reaches another level. He can very casually disarm and stomp Andy, who was roughly on par with early season 4 Thea. Whilst that was well before the bulk of her training with Oliver and her best showings against Malcolm, her fodder feats and S3 showings against Slade & (contextually) Oliver still put her on a very respectable level of skill. Skip ahead another season to S5 and he's beating Vigilante in H2H, forcing him to his knees with little effort and only losing when Vig pulls out a gun and shoots him in the chest. This is the same Vigilante who was consistently depicted as at least a mid-diff fight for S5-6 Oliver and could shoot arrows out of the air, making this one of Diggle's best, and most often overlooked, showings. In S6 he can stomp Black Siren as well as Onyx, who in turn can beat 5 armed guards and KO 3-4 people on the other side of a room in 4 seconds flat. Each season, Diggle's skill improves a sizeable amount. He's had a consistent growth as a fighter, and his current skill level is much higher than many give him credit for.

Comparing the two, it's clear that Diggle has Giyera outclassed in stats. Skill-wise it's closer and the edge could go either way, mainly because it's tough to judge a fighter like Giyera from one showing. Whilst Giyera will probably be able to use the walls to dance and flip around Diggle like he did against May, Digg should be able to force him into an H2H fight. Even if he can't, Giyera may end up going for one anyway as he won't be able to put Diggle down purely with his wall flips. if the fight ends up going that way, Diggle should win. All that allowed Giyera to do as well against May as he did was his agility and flips - whenever he got up close she was dominating him in a way that she simply wouldn't be able to dominate Diggle. Giyera's only chance against Diggle is keeping his distance, abusing his agility and going for long-range flips but I doubt that he'll be able to put Diggle down by doing that - Digg won't just stand there and let him do so. In a more traditional fight, which this will most likely come down to (just like it did against May), Diggle should beat him (just like May did).

Overall I'd side with Diggle, though Giyera has a chance to win if he abuses his agility and the environment. In an open setting without any walls or objects, Diggle would take this quite comfortably. Other than his ridiculous agility, Giyera doesn't really compare to fighters on May or Diggle's level - and his agility isn't enough to give him the win here unless he abuses it in a way that isn't really in character for him.

Giyera. Good fight.
