Yes, all of this is cannon. 4th place: Maris, at a whopping 10,000,000 years of age! She is partially angelic, so age does not seem to affect her much at all, her life expectancy is completley unknown. 3rd place: Psyhro, who recently turned legit 1,000,000,000 years old this year! he is an embodiment, so unless he dies in combat he can live as long as he wants! 2nd place, Ian, at a cataclysmic 999,800,000,000 years of age (rounded to the nearest hundred billion)! He is my second-oldest OC to date, but strangely he was born in 2009. He time-travells a LOT, spending the vast majority of his life in timeless areas, colorless zones, or in the past or future! 1st place: Mike is cannocally 999,999,999,999 years old! 1 more year until he is 1 TRILLION YEARS OLD, and that happens next year, 2022. It's rounded to 1 trillion because 999,999,999,999 is super tedious to type in such a little space. The same case as Ian, but he was born in 2008, and has his scythe, which in a sense grants him 'immortality', or allows him to activate enough of his energy to allow such a powerful spell. Trust me, you DON'T want to see how big his birthday cake would have to be to have a trillion candles on it.
