Escanor vs. Estarossa

Escanor vs. Estarossa is a battle between Escanor of the Seven Deadly Sins and Estarossa of the Ten Commandments.

Prologue
During the Demon Clan's invasion of Liones, Escanor challenges Estarossa, seemingly singling him out as the strongest of Ten Commandments.

Battle
Facing off against one another, Estarossa concludes that Escanor must have been the one to defeat Galan and almost kill Merascylla. Escanor warns him not to start hating him, because if Estarossa was affected by his own commandment the fight wouldn't be any fun. As the two share a good-natured laugh at Escanor's concern, Estarossa upper cuts him. He then punches him down, launching him trough the raised ground they were standing on. Estarossa then quickly kicks Escanor back up to the surface, making the Holy Knights above wonder if even he can defeat Estarossa.

As Estarossa moves in for another attack, he suddenly has a vision of the "sun" coming towards him, which is really Escanor trying to punch him. He blocks the attack, but as he is gloating suddenly becomes dizzy and falls to his knees. The other Commandments watching are shocked that Estarossa could be felled by a blow up recieved with his guard up, but Esstarossa is excited at the prospect of fighting someone he can go all out against, and summons a sword.

Escanor calls Estarossa impudent, and seemingly strikes him with Rhitta...only to gush with blood. The Holy Knights are shocked, but Ban and Gilthunder realize that it was Meliodas power, with a slight twist. Estarossa explains his power, Full Counter which allows him to reflect any physical attack with more than double its original strength. Escanor concludes that is why he felt pain and that he would expect nothing less from himself, to which Estarossa laughs at how arrogant he is. Estarossa asks his name, stating he'll definitely remember it, and Escanor replies, telling asking him to remember it before he dies. Escanor states that as Estarossa has decided to fight seriously, he will be respectful and do the same, and asks that his opponent doesn't die right away, and creates a miniature sun.

Estarossa asks if Escanor is serious, as unleashing that much power in the vicinity will kill all of those he's protecting, as we see the Holy Knights' armor begin to melt from the extreme heat. Escanor asks Ban if a certain lake is nearby, and after getting confirmation, he bunts Estarossa away a great distance with his attack, named Cruel Sun. He reiterates that he hopes his opponent won't die too quickly, and then sends Estarossa crashing into the lake. He launches an attack called Pride Flare, that causes the sun to release so much heat that it vaporizes the entire lake in an instant.

As Escanor lands, he sees Estarossa, with a shroud of darkness, who compliments him on the attack, stating that if he had let out his darkness even a little later he would have taken some serious damage. Estarossa uses his darkness to heal the wounds he did sustain, and says that they should finish this. Escanor agrees, but before he can attack with Cruel Sun again, Estarossa covers it in darkness. Estarossa charges, saying this is over, and Escanor asks why he would say that and retaliates. Estarossa uses Full Counter again. Estarossa deduces that because he can block out Escanor's sun, his magic power is superior, and as he can counter any physical attack, even Escanor must understand his position.

Escanor is puzzled by this, asking who decided that his attacks couldn't reach Estarossa, as Estarossa is shown to have a giant slash across his chest. He comments he couldn't even see Escanor's attack and that Escanor's tone has changed. Escanor then asks who decided that his sun was blocked out. Estarossa is astonished at the vision of Escanor towering over him, with his sun having broken through the darkness and grown much bigger, as Escanor's power skyrockets.

Escanor states the only one who gets to make decisions about what his power are himself, and tells Estarossa to die, as he hurls Cruel Sun at him one last time. Zeldris attempts to help his brother, but the both of them are sent flying far away, until they crash into what seems to be the ocean.

Aftermath
After sending Estarossa and Zeldris flying, Escanor begins to think of returning to Liones, but decides against it, stating it's been a long time since he's exerted himself so much, and that Rhitta is barely containing his power at the moment. He opts to wait and cool down a bit before heading back, as the lake-bed flames and smokes from his heat.
