Dina Fritz was the first wife of Grisha Yeager, a member of the Eldian Restorationists, and, before having her son Zeke, the last descendant of the royal family living in Marley. She was caught committing treason against Marley, therefore turning her into the Abnormal Titan that would later eat her husband's second wife, Carla Yeager.
Dina was a small woman; petite in her frame and relatively short. Her eyes were large and light in color as was her fair skin. Dina's blonde hair passes her cheekbones but does not reach her shoulders and is kept parted down the middle. It is a bit longer in the back than it is in the front and has some layers to it.
Not much is known about Dina, however, it can be deduced that she was a very loyal follower of the Eldian Restorationists. She had a generally soft expression, sometimes plagued with worry. Although Dina admitted that the purpose of Zeke's birth was to lead to Eldian Restorationists and was neglectful, she appeared to still love her son deeply, and was horrified to learn Zeke was the one who turned them over to the authorities.
