As a member of the Seven Deadly Sins, Ban is very powerful. His speed and strength greatly surpass that of an ordinary human, and his specialty is using his speed in conjunction with his ability, Snatch, in order to rip out opponents' organs, preferably their hearts. His most amazing ability, however, is his immortality. Thanks to drinking from the Fountain of Youth, all of Ban's wounds heal almost instantaneously no matter how severe. He also does not age, does not need to eat or drink, and is immune to all poisons. His immortality allows him to fight with a much more reckless style than most are willing. Ban's blood has healing qualities because it was fused with the Fountain of Youth, as seen by it being able to heal others' wounds and regenerate the Fairy King's Forest completely. However, Ban lost this ability after using the power of the Fountain of Youth to revive Elaine.
Due to his time subjected to the harsh conditions of Purgatory, Ban's endurance and durability have drastically increased. His physique has evolved and adapted so much that even after having lost his immortality, Ban could still withstand similar conditions and come out completely unharmed; this is shown when he suffers no injuries from the Demon King's energy storm, which could wipe out any living thing according to Gowther, to the point of Ban even calling it a gentle breeze compared to Purgatory. The limits of Ban's physical resilience are further demonstrated when he was able to withstand several blows from the Demon King with only minor injuries.
His physical strength and speed also increased dramatically from the many centuries adapting, living, hunting and fighting the Demon King in Purgatory. Ban's combat abilities had increased to the point that he was able to compete in physical combat, without using Snatch, against the Demon King in Meliodas' body, who had just overwhelmed the Sins and two of the strongest Archangels effortlessly.
