Oluo Bozado was a soldier of the Survey Corps hand-picked by Levi Ackerman to be included in the Special Operations Squad. He was a skilled soldier with a very high Titan kill record.
Oluo had a much older appearance than his peers, having more pronounced wrinkles despite being implied to be around the same age as his teammates. He had slightly curly, brown hair styled in an undercut and small eyes. He wore the standard Survey Corps uniform, as well as a cravat, and his eyebrows were often pulled down in a condescending manner, similar to Levi. Oluo purposely styled his hair and cravat to resemble his Captain, Levi.
Oluo was a very self-confident, outspoken individual, and enjoyed boasting about his own prowess. Despite his obnoxious demeanor, he was the best out of Levi's Special Operations Squad; his 39 solo kills (highest solo kills out of his peers, bested only by Levi) fueled his haughty nature. Though Oluo tried to come across as self-important, his cockiness was rarely taken seriously, and he was also shown to be somewhat clumsy, frequently biting his own tongue on accident.
