Reichtangle

has a rectangle head with the German Empire flag pattern on it, microscopic white eyes (Wich rarely shows emotions) and usually dresses formally.
he "doesn't" has a mouth, and when he shows it, it's usually be sure he wants to threaten or lick someone (his tongue is really long, being 25 cm. yes, really long). when his "mouth" shows up, it looks like a monster's, full of sharp teeth and sometimes black saliva.

he is autistic and has ADHD (yes, a autistic adult ^^), likes to draw and is really quiet. when he says something, it's short sentences and his English is broken. he also may use some German words on his sentences.
he usually stands with his hands behind his back because he likes it. he licks someone to show his affection, but it rarely happens.
he is usually blank, emotionless, but can be silly.
he tends to imitate someone when he sees them for the first time, if the person tilts their head to the side, Reichtangle will also tilt his head to the side etc.
