Notable Attacks/Techniques:

Full Counter: Meliodas can reflect an attack back at the opponent with greater power than what it once had. The drawback is that it's useless against indirect attacks as well as physical attacks.

Meliodas Full Countering several Holy Knight attacks

 

  • Counter Vanish: Instead of reflecting an attack, Meliodas can disperse it completely.
 

 

  • Revenge Counter: Meliodas soaks up tremendous damage and then deals it back even stronger. This technique is very dangerous as it Meliodas is required to take a large amount of damage


Demon Form: Meliodas is half-demon, and can access his demonic heritage to give himself a large boost in physical capacity as well as other abilities. While using it he is bloodlusted and looses the capacity for rational thought. Although, Meliodas managed to slowly control it as the series was progressing.

  • "Black Matter": When he access his demonic heritage, part of Meliodas body is covered in shifting black "matter", which he can manipulate and shape as well as extend it outside his body. He can use this to block attacks on his body, to form giant claws and blades to attack, or to fly, by forming a wing-like structure around his arm.

 

  • Black Energy: Meliodas summons a column of black energy above his target.


- Enchancement - Hellblaze: Meliodas can cast an ominous black flame around his sword increasing his cutting power. It's strong enough to permanently leave a scar on the likes of Ban.
 

  • Divine Slayer: A stronger version of Hellblaze. Meliodas' strikes enchanted with this do much more damage and have significantly more range.

 

Lostvayne: Meliodas' sacred treasure. Lostvayne allows Meliodas to create up to 5 clones of himself. Each clone splits Meliodas' power and they can all use Full Counter.
