Gowther「ゴウセル」 is the Goat's Sin of Lust「 色欲の罪 ゴート・シン , Gōto Shin」 of the Seven Deadly Sins. Gowther was revealed to be a doll, created by a great wizard in the form of his old lover, and is a former member of the Ten Commandments, serving as his creator's proxy during his time with the Commandments.
3,000 years ago. The majority of Meliodas' childhood is unknown but in the past, Meliodas was trained by Chandler and was the leader of the Demon Clan's Ten Commandments, bestowed with the Commandment of "Love" and regarded as the one most likely to become the next Demon King, for his strength and ruthlessness.
Mael is the strongest of the 10 commandments, as well as priorly one of the Four Archangels. Mael is the commandment of Love, and anyone who possesses hatred will be unable to inflict damage in a fight.
Yes. Meliodas and his brother are clearly the two most powerful of the Ten Commandments, with the assumption that Meliodas is slightly stronger implied since he was the leader. Meliodas flat out states in no uncertain terms that Escanor is stronger than him.
Labs that Zoom got his speed from Velocity-9 and conclude it's Jay Garrick. Then, in the episode “Versus Zoom,” we learn Zoom isn't Jay Garrick. Jay Garrick is a false identity. According to Hunter on Earth-2, he posed as The Flash to pretend to be a hero while he secretly caused terror as Zoom.
There is no way Silver surfer could keep up with the Flash. Flash's top speed is 20 Undecillion times faster than the speed of light. That is 20,000,000,000,000,000,000,000,000,000,000,000,000 times faster than the speed of light. Flash is faster in combat/reaction speed, Silver Surfer is faster in travel speed.
As Barry Allen's arch-nemesis and one of DC's greatest villains, Eobard Thawne is a solid candidate for the Flash's fastest foe. Known as both Reverse Flash and Professor Zoom, Eobard Thawne first appeared in The Flash #139 by John Broome way back in 1963, and has been making the Flash's life miserable ever since.
