Arg, short for Agrius, is the oversized meathead of the Darkspin crew.
Agrius is most likely a reference to Greek mythology, as Agrius was a mythological figure in Hesiod's Theogony that was the brother to Telegonus and Latinus, who are also the names of the other lackey's of Darkspin .
With bulging muscles and a deep, booming voice, he aptly serves as Medea's bruiser.
Argius debuted in Wicked, where he along with the other Darkspin members were assigned by Dr. Emmanuel Klipse to test Chase Suno in battle. While Medea was battling Chase, Argius, Latinus, and Telegonus were called in to assist their leader in battle until Chase retreated. Later, Argius and his comrades were called in again to assist Medea against Chase, though this time Bren and Jinja burst through the wall of the warehouse. Argius and Moonfire fought against the two, but was defeated and then he retreated with the rest of Darkspin.
In Appleseeds, he was shown along with the other Darkspin members inside a house in the Lowlands, planning their next attack on Team Core-Tech. Later, Argius dropped down alongside his comrades to where Team Core-Tech was and proceeded to battle them, but in the end his Moonfire was defeated by Evo and Glowblade.
In Deceit, he was shown at the end alongside the other Darkspin members inside a warehouse.
In Ice, he and the rest of Darkspin were hired to retrieve the ample amounts of Monsuno Essence from the Valley of the Five Tribes. Argius and Darkspin ambushed Team Core-Tech on their way to Northpoint and proceeded to battle them until Lock destroyed the dock that Darkspin was standing on. Throughout the episode, Argius and Darkspin were foiled in their attempts to follow the team to the Cave of Convergence, but eventually they caught up and kidnapped Beyal. Once inside the cave, a battle erupted between Core-Tech and Darkspin, but once Beyal woke up, Argius and Darkspin were blown out of the cave by Glowblade, falling all the way back to the base of the mountain.
In Remembrance, he and the other Darkspin members tracked down Jeredy Suno and attempted to capture him, but Team Core-Tech arrived in a Hopper and a battle erupted between both groups. Argius and the rest of Darkspin were eventually defeated when Chase had Lock destroy the bridge that the battle was fought on, sending the Darkspin Monsunos into the river below and causing Argius to retreat.
