Summary
Yor is undoubtedly among the most powerful characters inSpy X Family. Throughout the series, fans have witnessed this trained assassin accomplish acts that no regular human should be able to. No one in the franchise seems to hold a candle to Yor regarding strength, flexibility, agility, or battle instincts Nonetheless, the series has been hinting at a character who could become equally powerful with the right preparation,Yuri Briar.
Yor’s little brother has also been shown to have an almost supernatural physic. This means that the Briar genes are the source of superhuman physical abilities. While Yuri is already a capable security officer for Ostania, by training rigorously like his sister, he could surpass almost all other fighters in the series.

Spy x Family Finally Fleshes Out One of its Most Promising Characters
Chapter 89 finally adds some much-needed depth to Yuri Briar, opening the way to a more interesting character who exists outside of one joke.
Yuri Could Become One of Spy X Family’s Strongest Characters
The Briar Family’s Genes Have Blessed the Siblings
As theSpy x Familyseries has progressed,the feats achieved by Yor have confirmed that she is no regular human. She is strong enough to cut a tennis ball with a single blow of her racket, jump in between buildings, and stop moving cars with a single kick. While the series oftenuses her immeasurable strength to highlight comedic moments, there is no reason to believe that these actions do not take place in reality. While on a lower scale, Yor’s little brother has also accomplished some inhumane ventures.
During chapter #68,the youngest Briar sibling is hit by a moving truck at high speed. This kind of accident would have almost guaranteed the death of a regular human. Despite this, Yuri is later seen arriving at work, as if nothing had happened. His commander goes as far as to admonish him for being struck by oncoming vehicles more than once in the past. The only other character to have accomplished such a feat is Yor, as she was also struck by a car during chapter #59.

Another major proof of Yuri’s superhuman abilities occurred earlier in the series. When Yor’s brother visits the Forgers’ household to meet his sister’s husband in chapter #14, the Secret Police member is slapped by the older Briar sibling at full force. Yuri is visibly hurt after that attack, but he is still able to walk without any issues and even goes home by himself.When Loid received a kick from a drunken Yor, he fell unconscious shortly after, which proves just how resilient Yuri was to be able to walk on his own.
Yuri Could Still Increase His Strength Like Yor Did
His Training Has Most Likely Not Been As Rigorous As His Sister’s
TheSpy X Familyseries has maintained the past of the Briar brothers as a mystery for many years. Nonetheless, many hints have been given that point at Yor having beentrained as an assassin since a young age. In Yuri’s flashbacks, his sister can be seen returning home covered in blood, which implies that she was already working for the Garden as a teenager. If this is true, that means that she has been under an intense and complicated training regime ever since she was young. Her amazing reaction when the Shopkeeper attacked her solidifies this theory.
This intense exercise regime, as well as the Briar Family’s inherent superior physical condition, is likely what has turned Yor into such a powerful and precise warrior. Yuri, on the other hand, has almost definitely never been pushed past the regular limits of a human. His job as a Secret Police agent implies that he has only received the average preparation that a member of this government agency does. Despite this,his endurance and strength already seem to be above average. With proper training and time, Yuri could become just as powerful as his sister, andone of the strongest characters inSpy X Family.

Chapter #89 might have beenthe beginning of Yuri’s journey to becoming an overwhelmingly powerful fighter. During this chapter, the younger Briar sibling can be seen trying to imitate his sister’s fighting style, claiming that he will become powerful enough to keep Yor safe. Yuri’s training regime could lead him to unlock the superhuman strength that his sister possesses, becoming a serious threat to Loid and Operation Stix.
The Briar Family’s unmatched power and durability is one of the most intriguing topics of theSpy X Familymanga series. Yuri and Yor’s past will likely be revealed at some point in the future. The series might explain why and when the siblings acquired these superhuman abilities.
