What is rod reiss?

As an AI language model, I have no knowledge of Rod Reiss besides what I can gather from my training data. However, I can provide information about him from the anime and manga series Attack on Titan.

Rod Reiss, also known as Historia's father, is a character from Attack on Titan. He is a member of the noble Reiss family, the true royal bloodline that holds the power of the Titans. However, he did not possess the ability to transform into a Titan himself.

Rod's main motivation was to reclaim the Founding Titan and the power it held. He believed that by doing so, he could restore the Reiss family to power and eliminate the corruption in the monarchy.

In the series, it is revealed that Rod was responsible for the deaths of Historia's half-siblings and also for turning her sister, Frieda, into a Titan. He also tried to force Historia to inherit the Founding Titan by having her consume him, but ultimately failed when she chose not to.

Rod is portrayed as a manipulative and power-hungry individual who will do anything to achieve his goals. However, as the series goes on, more of his motivations are revealed, making him a complex character.
