Porco Galliard

Galliard appeared to be a brave figure, using his Titan to leap in the way of bullets and protect his fellow Eldians Gabi and Falco. It is, however, quite possible that Galliard was not acting on bravery and was instead certain of his ability to withstand gunfire with the absence of the anti-Titan artillery, indicating that he has fought on battlefields before. As a dedicated Warrior, he would charge right into the heat of battle, attacking an enemy gunman and crushing him for his people. He also had somewhat of a bitter personality, and was shown to treat others, particularly Reiner Braun, condescendingly. Galliard seemed to be prone to using passive-aggressive language, although this may simply be motivated because of his animosity towards Reiner. He is, or at least was, prone to violence, as seen when he punched Reiner after they had an argument. He also appears to be extremely arrogant in his own power, trusting that his Titan powers are more than enough to keep him alive against the experienced Survey Corps and was visibly shocked when they are able to essentially fight him to a standstill. It should be noted that despite his rude attitude, Galliard cared very deeply for his fellow Warriors. While he was initially cold and unwelcoming to their friendly advances, he showed great panic and anger when Pieck and Zeke Yeager are defeated during battle with the Survey Corps. Also, he showed himself to be quite a headstrong person, liable to act recklessly in critical situations. Driven by anger when he learns that Bertolt Hoover died and his former Titan is being used by Paradis to destroy the Marleyan fleet, Galliard rushed against Eren in a blind rage and oblivious to Pieck's pleas. This left both Pieck and Zeke more vulnerable to attacks, which was the opening the Survey Corps needs to defeat them afterward. This personality trait also got Galliard ambushed by Mikasa Ackerman, when she realized he will act carelessly once he saw the Paradis Island airship flying above Liberio. This led to him being mangled and used to destroy the crystal in which Lara Tybur protected herself.

Human form
In his human form, Galliard had the appearance of a young man of medium height and slender complexion. He had gray eyes, and his blond hair was in an undercut style which was pushed back. He wore combat trousers and a short coat. He also wore the Eldian armband on his left arm, as required of all Eldians under the authority of Marley. While undercover on Paradis Island, Galliard stole a Garrison uniform to disguise himself as part of the Yeagerists.

As an Eldian Warrior, Galliard had undergone advanced military training in order to prepare him to use the Titan power. He was in very good shape and his overall abilities were strong enough to make him an Eldian Warrior.
