Apart from attacking with punches, they are surprisingly adept with stabbing weapons as they can charge players with said weapons. A standard punk, they are dangerous only in groups.
Streets of Rage
In the first Streets of Rage, he is capable of spawning, throwing, stabbing or charging with knives, grabbing the player from behind, using a 3-hit punch combo ending with a knockdown, and wielding a metal bat. Knife Garcia can either stab and throw or charge, with none being able to perform both actions.
Streets of Rage 2
In Streets of Rage 2, Galsia's moveset has been vastly simplified compared to the first game, being the standard street punk with low health and no special attacks. Just like the first game, certain stages, he'll appear wielding a knife and charge at the player; however unlike the first game, if knocked down, he'll not attempt to pick up the knife again. His limited moveset is compensated by one-frame jabs that, when surrounded by several Galsias, can cause a lot of damage and pressure. In fact, some of the things Galsia did in the first game can be done by Donovan, Jack or Storm in this game.
Streets of Rage 3
In Streets of Rage 3, Garcia (Galsia in Bare Knuckle III) is similar to his Street of Rage 2 counterpart, but with an expanded moveset, most notably his elbow drop, which covers large distance and is difficulty to intercept. In addition, Garcia and other enemies are capable of picking up health items laying on the ground, as well knives on the floor. He can also be picked up by Bongo/Big Ben and be thrown at the targeted player. In certain stages, he will also try to jump off parts of the level background. His 3-hit punch combo is absent and was instead given away to Slum and Vice.
Streets of Rage 4
In Streets of Rage 4, he retains the more simplistic moveset from Streets of Rage 2, and can no longer use his jumping elbow drop from the third game. but, in addition to knives, he can also wield sais, broken bottles, tasers, and naginatas as well; the latter makes him extremely dangerous because his charge attack will have a much longer reach. While he no longer has special attacks when unarmed, he retains his 1-frame jab, making him dangerous when surrounded.
During the boss fight with Nora in Stage 3, she can whip the spawning Galsia enemies in the room which turns their hair blonde, making them more aggressive and granting a perpetual super-armor (although they can still be grabbed). Their name will also change to "Galsiaaaaaa".
Aside from "Galsiaaaaaa", all his variants are virtually the same, but with higher health.
