God class / transcended beings
-------------------------------------------------------------------
Transcended beings - beings whose power is on par with god class beings without being ones... (even if they would gain divinity they would still be considered transcended beings rather than god class beings)
- Archangel - the angel's variation of Transcended being (example: Lucifer)
-Super-Devil - the devil's variation of Transcended being (example: Rizevim)
*******
Lucifer doesn't have 14 wings due to him being a transcended being (Archangel) but rather because he is the first angel (Meaning: the additional 2 wings is something completely unique for Lucifer and as such no one (no angel/fallen/devil) could have more than 12 wings... (Not even his descendents))
