Ogweno (オグウェノ Oguweno?) is an ambassador from a foreign land and a friend of Willy Tybur. He serves as one of several ambassadors for his nation during the Liberio festival following the Marley Mid-East War.
Ogweno is an old, clean-shaven gentleman with close-cut hair and brown skin. As ambassador, he dresses in a quality tuxedo and bow-tie.
On the eve of the festival in the Liberio internment zone, Ogweno and Nambia attend a gathering of world ambassadors. They joyfully greet Willy Tybur, an old friend, during the festivities. Ogweno joyously applauds Willy before his speech, calling him "kin of our savior."
Ogweno sits near the front of the crowd on the day of Willy's production. He learns a more accurate depiction of history. This history discredits the Tybur family, but he seems to hold no ill-will about the matter, tearing up at Willy's bravery in telling the truth. Ogweno remains emotional when Willy laments his Eldian blood, and requests the world to unite in the effort against Paradis Island. When Willy Tybur declares war, Eren Jaeger bursts through the building behind the stage, which he crushes. This attack eviscerates Willy, and sends debris into the crowd Ogweno stands in.
Eren's transformation and his brutal devouring of Willy causes a panic in the audience. In their effort to get away from the Titan, Ogweno and Nambia rush away from the stage amidst the crowd.
- Ogweno and Nambia are the first black characters introduced in the Attack on Titan anime, resembling those of African ethnicity in our world.
