Dalia is a character introduced in Metal Slug: Commander.
Dalia a famous Japanese mercenary who is known for always winning her battles. She gradually grew tired of her mercenary life, yet she had a hard time pursuing any new ventures. This eventually changed when she noticed Morden and grew deeply attracted to him. Dalia ultimately dropped her mercenary career to join the Rebel Army.
Dalia entered the force during the time the Rebels were scouting an operator for their new machine. She was able to earn her position by passing their practical exam without any problems. Dalia's strength and skill as an operator increased to where she has yet to be bested by any Regular Army mechs.
- Although debuting in Metal Slug: Commander, Dalia makes a brief cameo in Metal Slug Attack's promotional gift campaign for the former game.
- Some of Dalia's in-game sprites fail to load during gameplay and appear as black boxes.
