Floch appears to be of medium height with short, tousled red hair. He wears the standard Scout Regiment uniform.
Floch appears to be somewhat lacking in self-awareness, being one of the many Scout Regiment recruits to freely show excitement and even celebrate the upcoming mission to reclaim Wall Maria, seemingly without consideration for the danger that will be involved. He also appears to be somewhat narcissistic, showing an unwillingness to admit that other graduates from the 104th who joined the scouts before him are more experienced than him.
During the feast before the expedition to Shiganshina District, Floch overhears Jean Kirschtein badmouthing the new recruits who have transferred to the Scout Regiment and jokingly confronts him, noting that they all trained together in the 104th. Floch is left uneased by Jean's nonchalant attitude toward him, noting that the cadets who joined the scouts after graduation have changed greatly since the last time he saw them. He begins to ask what happened to them, before thinking better of it and leaving.
Floch, along with other scouts, takes part in the operation to retake Shiganshina District. He and the rest of the recruits enter Shiganshina on foot while the rest of the soldiers use their ODM gear to make their way on top of the Wall. They are ambushed by Beast Titan, who appears with an army of Titans and throws a boulder into the side of Wall Maria, causing a collapse which blocks the scouts' entrance to Shiganshina, leaving Floch and the other recruits unable to enter with their horses. Floch and his squad mates are left in charge of the scouts' horses, and are ordered to defend them from any approaching Titans.
The Beast Titan suddenly begins targeting its throws at the Scouts themselves, and Levi orders the recruits to take the horses closer to the Wall, where they can use buildings for cover. Floch begins to panic, and Levi has to force him along to the base of the Wall. Marlo scolds him for letting some of their horses run away in the attack, but Floch in a frantic state says that it would be pointless to watch them if no one is going to survive for the return home.
Thinking back on the ceremony where he decided to join the Scout Regiment, he remarks that he thought he could be a brave soldier willing to give up his life for humanity, only to realize now that he is not and that his death will be meaningless.
When Erwin Smith gives his plan of a suicide charge against the Beast Titan to the recruits, Floch asks if they are going to die and if it is better to die fighting, wondering if it all would mean nothing. Erwin agrees that they are all likely to die, but he urges the recruits to fight for the good of humanity nonetheless so that the living can give meaning to their deaths. Floch participates in the suicidal charge against the Beast Titan.
