Tyburs are nobles and normal eldian, Annie being related would be odd since the Tyburs are filthy rich and the Tyburs do not have special abilities like the Fritz family. Marley calls it the Female titan and know much more about the 9 titans so that should be its offical name and Magath mentionted screaming is its natural ability. Eren ate a serum called "Braun" but its pretty impossbile for Rod to ever have gotten anything Reiner since it's clear they never met. I really don't see how eating a another of the 9 titans serum would do anything. Should that be the case then why hasn't Marley just simply upgraded all of their shifters?
