Henning had short brown hair that seemed to be pointing towards the back of his head and he wore the typical Scout Regiment uniform.
Little was known about his personality, but due to the fact that he chose the Scout Regiment instead of any of the other military branches, Henning was a man who wanted to fight the Titans to guarantee mankind's survival.
Henning is one of several soldiers, including Gelgar, Nanaba, Tomas, and Lynne, brought by Miche Zacharius to oversee a group of potentially untrustworthy Scout Regiment members. The group is assembled close outside of Wall Sina, and disarmed of their weapons due to the suspicions that one of the new recruits might be an accomplice to Annie Leonhart.
Before an investigation can begin, Titans appear within Wall Rose. Miche orders the group to split into four squads to warn the nearby villages. Henning is in Nanaba's team, which begins searching Wall Rose for breaches. However, the squad encounters Gelgar's squad coming from the opposite direction without finding any, signifying that there is no breach. As night falls, the two groups take refuge in Utgard Castle.
Utgard Castle soon comes under attack from numerous Titans capable of moving during the night. Since the soldiers who had been under suspicion do not have omni-directional mobility gear, the only ones able to directly engage the Titans are Henning, Gelgar, Nanaba, and Lynne.
However, when Henning and Lynne separate from Gelgar and Nanaba to check on the rookies within the castle while Nanaba and Gelgar eliminate more Titans, they are both struck by a projectile thrown by the Beast Titan which kills them instantly.
