Tom Ksaver

Tom is a minor antagonist from Attack on Titan. He is an Eldian who are a race of humans capable of becoming large humanoids called titans. He is a citizen of the country of Marley who enlisted in the country's Warrior program and inherit the Beast titan but sometime during it he'd hide his Eldian heritage after having a family with a Marleyan and upon her discovering his origins, she would ultimately kill herself and their child which nearly drove him over the edge of depression until he met a candidate named Zeke who would later inherit his titan. During his time as a Warrior he'd do research into titan origins rather than being involved in combat due to the lacking effectiveness of his titan. It was then that he inspired the euthanasia plan he and Zeke would agree to in order to save Eldians from future suffering.

He is a young adult of average build with slightly rounded facial features. He also has gray eyes and short black hair and also seems to wear particular rounded glasses which he'd later pass down to Zeke.

As an Eldian he's capable of transforming into the Beast titan that he was granted. His in particular appears to be of a humanoid build with the features of a ram around the head. His only notable means of combat in this fashion are charging headfirst using the curled horns of his titan. As a shifter he is also granted regeneration.
