[Super Devil] basically means a Devil who has "transcended" Devils.

Whether they're [God-Class] is another thing entirely.


 * Sirzechs - He has mastered his [Power of Destruction] to the point that it isn't a "power with destructive capabilities," but the very "concept of destruction itself." This basically means that even if you're the most durable, unbreakable thing/being in existance, Sirzechs can just ignore that and wipe you from existance. The only reason Trihexa (666) was able to survive was because it regenerated faster than Sirzechs could destroy it.


 * Ajuka - He's customized his Demonic Powers to the point that he can take control of any phenomenon around him, and modify them to make them stronger, faster, etc., and attack his enemies with them. He demonstrated this, in vol.12, by taking control of the Demonic Power attacks the Old Satan Faction fired at him, modified their shape, power, speed, and attributes, then fired them back at the Old Satan Faction.

Sirzechs, Ajuka and Rizevim are [Super Devils] because their Demonic Power puts them above other Devils. But Sirzechs and Ajuka are so much higher than Rizevim because they trained and mastered their powers, obtaining abilities that put them in the same league as the Higher-Level Gods.
