There are Snake sage, toad sage..Time to make the unique sage of Izuna itself! The dragon sage!(Dragons are the primordial of all beasts.) To make it more OP, try the Dragon Elephant sage! I'd suggest reading what's a dragon-elephnat..now a days some new Xianxia novels are using this term of a strongest creature(To be honest this is my fav beast due to how amazing it is). Make a sage, unique to Izuna, the combination of all sage beasts throughout the Naruto world. This will make the unique Izuna sage; the strongest sage in the whole world.
