15Billy Watkins
A Young Boy With Incredible Potential
What Makes Billy Strong?
When thinking about individuals with over-average physical strength, children rarely come to mind. However, a clear example is an infant who could beat a grown man in a contest of strength in Eden Academy, Billy Watkins.
Anya’s schoolmate has been trained since he was a toddler to becomean exceptional athlete. Despite his young age, Billy has enough strength to seriously harm someone, as seen during the dodgeball game between Anya and Billy’s classes. Nonetheless, he is still a child, so he has a long way to go before surpassing the most powerful characters in the show.

14Daybreak
Twilight’s Self-Proclaimed Rival
What Makes Daybreak Strong?
Being a spy is not an easy job by any means. You need to be intelligent, agile, diligent, cautious, daring, and work in the shadows.

The secret is selecting solid source material.
Still, he does seem to have the condition necessary to be a spy. He could infiltrate Eden Academy without being detected, as well as break a window with his elbow without so much as complaining. Sadly, the lack of proper training means that his strength will most likely not increase.
A Certified Good Boy
What Makes Bond Strong?
Pets in anime are rarely utilized as well as Bond was in Spy x Family. He was a dog with some unique abilities, such as peering a few seconds into the future, similar to Anya, and was the result of brutal experiments. However, despite his tragic past, he seems to be the most loving dog in anime and routinely helps Anya save the day with his abilities.
In the story, Bond’s involvement is significant as he is an integral part of the Forger family and provides comedic relief, such as how he dreads whatever Yor feeds him before she does. He’s a hero in that sense, and his abilities make him one of the strongest characters in the anime.

12Martha Marriott
Anything But Frail And Old
What Makes Martha Strong?
At first, Martha may seem like Becky Blackbell’s sweet and elderly personal nanny. However, you better not underestimate this respected older woman. Before working for the Blackbell family, Martha served as a soldier in Ostania’s military.
As stated by Loid when he first met, Martha could be working as an undercover bodyguard for Becky. She carries herself like a warrior, always ready to strike against those who dare hurt Becky. Sadly, due to her advanced age, it is likely that she does not have the same strength as she did in her youth.

Little Screentime But Established Himself By Surviving Against Loid
What Makes Nguyen Strong?
Before adopting Anya and beginning his work on Operation Stix, Agent Twilight was tasked with investigating a small but powerful criminal organization. After Anya became a part of the Forger Family, she mistakenly sent a message through Loid’s communication device, which got intercepted by this organization.
To make sure that Twilight was silenced, they sent a group of brawlers to take him down, lead by Ngyuen. Despite his brief appearance, the man proved to be a proficient fighter, forcing Loid to narrowly avoid many of his hits during their short confrontation. Still, he was beaten quickly by Loid, proving he was not the strongest fighter in Ostania’s criminal world.
10SSS Lieutenant
Cold, Calculated, And A Stoic Threat To Loid
What Makes SSS LieutenantStrong?
The SSS Lieutenant is an enigmatic figure operating within the Ostania State Security Service. He’s Yuri Brair’s supervisor and even has an intimidating appearance with scars on the left side of his face. He’s a dedicated individual and is solely focused on doing his job, eliminating any potential spies, and looks to eventually eliminate Twilight.
Though despite his cold and calculated appearance and methods, he’s kind to his subordinates, like Yuri, and his intelligence is his strength. Though he isn’t a field agent, he is a threat to Loid and, as such, deserves his spot.
9Yuri Briar
Potentially Psychopathic Elite Officer
What Makes Yuri Strong?
Yuri, Yor’s younger and slightly unhinged brother, works as an agent for the State Security Service, Ostania’s elite police force. He chose this job due to his deep love for his older sister, whom he wants to keep safe from all danger.
10 Anime You Should Watch If You Love Lycoris Recoil
Lycoris Recoil isn’t a long show, but it offers such a distinct premise and experience. This list breaks down anime that scratch a similar itch.
As an elite officer, Yuri has gone through rigorous training to ensure he has what it takes to keep his country protected. While we have not seen him use force often, the few times, he has proven that he is not a man to mess with. Nonetheless, Yuri has not done anything too out of the ordinary, which is why he cannot be considered one of the strongest characters in the show.
8Shopkeeper
Leader Of An Elite Group Of Assassins
What Makes Shopkeeper Strong?
The Garden is the most notorious group of assassins working in Ostania. Since their missions often make them fight against many enemies at once, they have to be some of the most powerful and skilled warriors in the show.
The Shopkeeper is the leader of these intrepid fighters, being the one who controls the entire operation. Although we have not seen him fight yet in the show or the manga, Yor herself seems to hold the utmost respect for this man. Sadly, until he proves his strength, we will have to keep imagining how powerful he is.
7Sickle And Chain Barnaby
A Man Who Lives Up To His Name
What Makes Barnaby Strong?
Of the colorful cast of characters present in Spyxfamily, Sickle and Chain Barnaby is aptly named since he carries a sickle on a chain as a weapon. He’s an assassin who was sent to kill Olka and Gram Gretcher, and the strongest of the group sent after them.
He makes his debut in the cruise adventure arc and is shown to be a selfish and greedy man who wants to keep all the bounty for himself. His strength was enough to even give Yor trouble while she was protecting Olka and Gram, showing just how powerful he was. Eventually, Yor managed to tie him up with his chain, which made him harmless for the rest of the trip.
6Winston Wheeler
What Makes Winston Strong?
Winston Wheeler is a spy for Ostania who manages to infiltrate the WISE agency and successfully becomes a double agent and leaks information that Westalis holds against Ostania. To reach his position required a fair amount of cunning, but strength plays a role too.
After being discovered as a mole, he fights Twilight and even impresses him with his fighting skills and is good at utilizing weapons and his own hands during combat. His strength level, for this reason, is considered above average until he’s eventually defeated by Fiona.
