User blog:Dark Doctor/Immortal Marco

This is just a radom thought I had while looking through the un-named devil fruit list. If Marco's fruit is a Phoenix, does this mean he has an incredibly long life span? For any who dont know,the Phoenix is said to live for five hundred years. If this is true, does that mean Marco could have been part of White beards crew over twenty years ago? I would love to hear your thoughts on this one.
