As mentioned in this post, where normal Tyson as a teenager was a punk, Teen!Verse Tyson leans more towards being a pastel punk/hipster.
As a teenager in Orphan AU, away from his father’s abuses, Tyson has much more confidence in expressing his own style; rather than the more subdued, secretive choices of the teenage Tyson from his main!universe.
This general premise invokes the main difference between teenage Tyson & teen!verse Tyson. Teen!verse Tyson still fences, plays cricket, and skateboards, but unlike teenager Tyson, he does so with confidence rather than second-guessing his every action. He has anxiety, but it isn’t the same noose.
Where regular Tyson had an incredibly isolated childhood that meant he missed out on learning a lot of key social skills, ones that took him years to scrounge together as an adult and that he continues to struggle with due to a lack of confidence in himself, teenage Tyson grew up surrounded by people.
He finds that smothering and frequently goes off to find some peace and quiet on his own, but that meant that Tyson learnt those social skills at the appropriate age. He is in a much better place mentally, even if his abandonment issues sprung up much sooner after getting abandoned by his mother and father in quick succession.
Where teenage Tyson had a slight DC bias, teen!verse Tyson has a slight Marvel bias due to the comics they grew up/are growing up with. Their interests are more or less the same, but teen!verse Tyson is more willing to show his interests rather than hiding them.
