THIS IS PURELY FICTION, SOME CHARACTERS MAY GO OOC (or definitely OTL) , I'll try my best, BUT THIS AINT SUITABLE FOR THOSE HARDCORE ANTI-OOC PEEPS

POWER WILL BE CLASSIFIED UNDER 3 CATAGORIES: ENERGY, MAGIC AND DEMON POWER

CHARACTER'S POWER MIGHT EITHER BE NERFED OR STRENGTHEN, DEPENDING ON MY MOOD- I MEAN, SITUATION.

The characters, some will be at their stronger (example: Medaka will have Mars mode, Train will still have railgun), some will be weaker ( Zatch Bell will not have Golden Book).

OC – Ability is Re-quip of weapon and armor, similar to Erza Scarlet's ability. Based on my AQ Battleon character :D
