At eight years old, he was somewhat tall for his age, since he was two years younger than Sabo but was still about the same height as him. He wore a shirt with frills going down the middle along with a bow-tie and suspenders. He was often seen smiling. He had a round head with a thin, flat nose and a bowl-shaped haircut.
As an adult, Stelly is much taller, wearing a shirt with a sash on the back, frills on his shoulders, and a high collar. He still has the same hairstyle as he did as a child.
Like most Nobles shown from the Goa Kingdom, he is an arrogant person who does not care for anyone that is of lesser status than himself, referring to them as trash. This extends to referring to Sabo as "stupid" and "trash" due to what he heard from their parents, all casually, disregarding any manners or respect. However, Stelly can put up a facade of good manners and devotion in front of his foster parents. He is also not very brave, crying in fear when Sabo threatened him, and shunning any responsibilities when Sabo ran away again. In short, he is the complete opposite of his older adoptive brother. Stelly also seems to be intelligent, according to his teacher and adoptive parents, due to his higher status upbringing, and Sabo's father desiring him to be the back-up heir.
As an adult, Stelly still acts rudely to people of lower status and acts spoiled, as he complained about his lavish living quarters on Loguetown.
When he was eight years old, Stelly's birth parents were unable to continue raising him and he was adopted by Outlook III since he had shown lots of promise. When Sabo was brought home by his father, Stelly introduced himself to him. Stelly later visited Sabo in his room, telling him if he will not succeed and that he would replace him, becoming the new successor. He also told Sabo that he had the devil's luck, saying that if he had stayed in the Gray Terminal, he would have died. Sabo grabbed Stelly's shirt and demanded him to tell him everything. Stelly then told Sabo about an impending visit from a World Noble and plans to burn the Gray Terminal to make the kingdom clean of trash.
Totto Land ArcEdit
As the time for Reverie approached, Stelly and his wife were staying at a hotel for royalty in Loguetown. He commented to his queen that the hotel is nothing special, only offering a view of Gol D. Roger's gallows.
