Orga is a pale-skinned, very massive and heavily muscular man, possessing extremely well-built arms and torso, and normal-sized legs which, in comparison, look small. He has long, light green hair, reaching down below his shoulders, which is arranged into a variety of massive spikes jutting outwards, with a pair of them going down vertically framing his face, and those topping his head pointing outwards, being held in place by a plain black band covering Orga's forehead; his eyes have a similar though visibly lighter shade to them. He possesses an elongated, almost rectangular face, which is usually shown retaining a frowning expression, with Orga's linear eyebrows being placed diagonally at his eyes' outer sides, pointing upwards, and his mouth sporting a slight grimace; covering his flat chin is a distinctive beard, consisting of four horizontal black stripes placed one near the other. His massive shoulders and biceps are adorned by large dark tattoos, with each arm bearing a circle flanked by a pair of slender objects, reminiscent of both wings and elongated leaves.
Most of Orga's muscular upper body is left exposed: his clothing only consists of a light, striped pair of pants, with a large, tiger-patterned cloth with furry edges secured around his waist by a plain light band. He also wears dark armbands with light edges circling his massive forearms, each bearing a pair of small furry balls on its outer side, near the hand, and dark shoes with light soles, sporting similarly light, simple elongated motifs on their upper part. Circling his massive neck are three golden-colored, plain ornamental rings.
Orga seems to be one of the quietest members of his team, rarely ever talking or changing his usual, neutral expression, not even on the battlefield, when confronted with an opponent. In such cases, his demeanor appears to remain the same, with him striking the foe down with no seeming transport or emotion. He did show, however, a completely different, odd side: after the instantaneous defeat War Cry suffered at his hands, when Sting Eucliffe nagged him for not making his battle "more exciting" to behold, Orga plainly went on to say that he would have sung a song, something which he subsequently did, pulling out a microphone from nowhere and using off-pitch words to exalt his guild, much to the surprise of the members of Fairy Tail's team A and to the joy of the Grand Magic Games' audience. He was also rather baffled when he saw that Jura got a way higher score, than he did.
Grand Magic Games arc
After successfully claiming first place in the preliminary rounds for the X791 Grand Magic Games, Orga enters the arena with the rest of his team to enormous applause. He's later chosen by fans to take part in the third battle of the first day of the Grand Magic Games against War Cry of Quatro Cerberus. War Cry immediately attempts to use his Tear Magic on Orga, however Orga quickly defeats him with his Black Lightning Sphere. After the fight, Sting asks Orga if he couldn't have made the battle more interesting, to which Orga replies by singing a song that exalts Sabertooth. 
Orga would chastise Sting for failing the Chariot event and was later shocked to see his teammate Yukino Aguria lose in her match against Kagura Mikazuchi. With her defeat, Team Sabertooth gains 0 points overall in the second day of the Games.
Orga is present the night Natsu Dragneel attacks their lodging and is just as shocked at the sight of Natsu's rampage as the rest of his guildmates.
On the third day of the Grand Magic Games, Orga chooses himself to represent Sabertooth for the Day's event. The event, Pandemonium, consists on defeating monsters of different levels to earn points and progress. However, the event is finished by Erza Scarlet alone, which amazes the entire audience. When the "MPF" is announced, Orga later strikes the MPF machine with his 120mm Black Lightning Cannon, gaining a score of 3,285, surpassing Millianna, Nobarly, Hibiki and Obra. After his turn, he sings, however, when Jura strikes and gains a larger score than him, Orga becomes shocked.
Magic and Abilities
Lightning Magic (雷系各種魔法 Kaminari Kei Kakushu Mahō lit. Various Lightning Magic): A form of Magic which Orga is known for employing in a peculiar way, summoning forth at his command electricity which, unlike normal one, is black in color. Such distinctive "Black Lightning" of him, granting Orga his epithet, possesses high voltage and great destructive power, and, much like that employed in standard Lightning Magic, can be generated in places away from the caster.
- Black Lightning Sphere: Orga brings one of his arms forward, the elbow slightly bent, creating a very large sphere of black lightning, with its sparks occupying an even larger area around it, in a location which can be some meters away from him. This is generated around a certain target, which is subsequently electrocuted. The sphere can be formed almost instantaneously, being fast enough to prevent opponents who might have already started casting Magic from completing their spells, making for an extremely effective form of offense. This spell was powerful enough to defeat War Cry of the Quatro Cerberus guild with one hit. (Unnamed)
- 120mm Black Lightning Cannon: A focused attack which is initiated by Orga horizontally placing his hands before himself, their partially open palms facing. Tiny sparks of the man's signature black lightning are generated between his hands, growing larger and larger in semicircles as an electric projectile is fired from their center towards the target. Despite is reduced size, the generated blow is strong enough to create a mildly large curtain of smoke when it connects with the enemy, and it was noted to possess an astonishing amount of Magic Power, 3825, when fired against the Magic Power Finder. The 120mm is a large weapon caliber employed to load very massive cannons and mortars; hence the spell's name.
Immense Magic Power: While nowhere as abundant as the Wizard Saint Jura Neekis', Orga has been noted to possess large reserves of Magic Power: when firing his 120mm Black Lightning Cannon against the Magic Power Finder during the Grand Magic Games, he was able to achieve 3825 points, a score which left two powerful Mages the likes of Natsu Dragneel and Gray Fullbuster blank, and which was noted to be ten times the average score of a Rune Knights' Squad Captain. Even Laxus Dreyar, an S-Class Mage known for his great Magic Power, was shown to be positively impressed, sneering satisfied. Orga's Exceed guildmates Lector and Frosch described him as being unmatched in terms of sheer Magic Power within Sabertooth, a guild which is currently considered the strongest in Fiore, and which counts two Dragon Slayers among its ranks.
