Cero The Black Tiguar Older

Cero returns tries to return to his era only to wind up stranded in the passage of time, his aging speeds up then stops him at age 27, he masters his elementalist skills and his Nullification abilities but as a sacrifice loses all of his memories. He has lost all memories not vital to his survival at this point his story would consist of making new ones that replace the lost ones(I.E. meeting Blaze and other Sonic Canon characters over again.)
