Engel's alternate appearance as a child shares many similar details to his normal appearance. His messy hair is a reddish-orange hue and is tied into a low ponytail. He wears a dark orange Tyrolean hat on his head, with two feathers, one blue and the other reddish-orange.

He wears a white collared shirt with two blue and red stripes on the left sleeve, accompanied by black overalls.

Engel appears to be kind and caring, willing to go to extreme measures to protect those he cares about. This is shown in Behavior Basics when he befriends Claire and is later willing to risk his life to save her from Miss Circle.

Engel is seen in Miss Circle's math class, looking annoyed with Oliver, Zip, and Edward as they throw trash and paper airplanes at Claire. He later befriends Claire in the library and the two talk, before Claire is abruptly picked up by Edward's drone and thrown into a hole. Engel later appears in the episode to protect Claire, stopping Miss Circle's compass as it is about to kill Claire, giving her time to run.

He is then thrown against the wall, causing his right eye to bleed black ink and turn red. Seeing Claire's dead body, he is distraught to see her in such a horrible state.
