In a now deleted tweet by VIVINOS, it was mentioned that Till is the most sensitive, delicate and timid among all the participants. [2] This is confirmed by the art book's skill stats in which he is shown to have the lowest mental strength out of the included participants. His shy nature was especially present in his childhood when Till admits to have drawn Ivan a lot but feeling too embarrassed to show it to him.[3] It also manifested in his crush on Mizi as she said in the art book that he tended to avoid her.[4] During his teenage years his timidness and introversion translated to self-conscious demeanour which was demonstrated in a lot of artworks by overly blushing and getting frazzled, most of which around his crush.[5][6] However, it was also stated he tends to "lose his mind a bit" when it comes to art or Mizi.[2] This corroborates his depiction in Round 2 where he is shown to improvise a song for her, as well as his outbursts after the events of Round 5. Till has quite the rebellious streak, which is particularly evident in Round 2 when he sings over his opponent in order to win, or in the flashbacks of Round 6 when he openly defies Urak. It was even stated that he was so unruly that the aliens had to take extra measures in Round 2 by leaving his collar on, which was not usually done as it interfered with participants' performance.[7] Apart from this, Till is also noted to be an exceptional artist, or even a prodigy, though he is said not to recognise it himself[7]. It was said that when he hyper-focuses on a task the whole world around him seems to fade away.[2] In the series, Till is often depicted drawing or composing, suggesting he is very creative. In the comic "True Face" Mizi asks him why does he like her Till replies with "because you're pretty"[8] which right with his floral artworks indicates he holds appreciation for beauty, though not necessarily in a shallow way. He is portrayed as extremely loyal which manifests in flashbacks in Round 6 when he refuses to leave Anakt Garden without Mizi, despite greatly valuing his personal freedom. His loyalty is also shown in the comic "Remember Everything" where Till still considers Ivan and Mizi his family, and even wants to find Mizi, despite having seven years passed since the final events of Alien Stage.[9] Till is a tall, but thin man with fair skin, teal eyes, and shaggy grey hair that sometimes appear to be dull cyan. On the side of his neck is his name marked in silverish-grey, usually covered in a green patch(In some official illustrations and stills from clips, he has two green plasters on the sides of his neck.) for most of the series. It isn't until the events of Round 6, where his branding is officially shown
