Owen is a new character introduced in Metal Slug Attack, making his debut in the Extra Ops "United Front the 4th".
A Ptolemaic Army guerrilla captain, he is a strong leader and is looked up to by his allies, who call him "Colonel" Owen. He is fairly thoughtful and laid back, telling Dragunov that their ranks are just "titles".
He uses special gauntlets to attack his enemies.
Dragunov, suspicious of Ptolemaios and Mira's hidden agendas, tasks Owen with spying on Mira to see if she is doing anything suspicious. He also told her that he picked up someone in his travels. Owen makes his way to Mira's last known location where she is seen attacking a Rebel facility alone.
Marco was also at the facility, attacking the base with a newly built "Golden" Slug Gigant after the Rebel Army had attempted several worldwide attacks which were barely repulsed. As Owen arrived at the base, he saw several black flames in the distance which he immediately knew was Mira's. However, he bumped into Marco, and fought him because he was in his way. He easily destroyed the Golden Gigant and was about to finish off Marco when he saw Mira's flames in the distance. He warned Marco that he was lucky to be alive before departing. Mira had anticipated Owen's arrival and knew what he was there for, which Owen tried to deny. He asked her what he was planning to do with the dead soldiers, but Mira cryptically stated that he would know in the future before teleporting away.
When the Ptolemaic Army begins their attack against the Golden Kraken, Owen accompanies them to assist the rookies participating in the battle.
After this operation, the Ptolemaics developed a golden version of "Deneb". Owen entrusted the machine to a petty officer as part of his orders, though he does not state why the officer is allowed to drive it when he asks him. When the operation is finished, Owen speaks with Dragunov about the battle. Owen felt that someone had been watching him and that it made him uncomfortable.
- He is the first Ptolemaic male character to be introduced in Metal Slug Attack. He also uses a different death animation compared to other members of the army.
- His appearance is loosely based on Shen Woo from King of Fighters and Geese Howard from Fatal Fury.
