I assume Philza's older bc of the joke "His name is Philza and he is quite old" and a bunch of fanfics convincing me that he (philza) lived for many decades

But slimes lived longer than humans (or thats why my parents say) so maybe Charlie

Idrk ask the others

I Think Philza is older

Both /j

Honestly, I think if you tried to ask either of them (assuming you're using the Immortal Headcanon) neither of them would tell you how old they are. Phil would just give wildly contradicting answers anywhere from "20 years old" to "I remember going to the Syndicate stronghold when people still lived there" and Charlie doesn't know what an age is

Lmao-

Yeah, Charlie doesn't understand much about the concept of time. And Phil's just likes to keep his age secret.

Yeah. They both seem ancient. I suppose since after Quackity's stream, Charlie has been around in some form or other for the majority of the time that the world has existed (which technically isn't that long since the server was made just over a year ago, but regardless), while Phil still had to be born and stuff, he just could have been born any time that humans existed, charlie might be older. Idk though. Also @Teatako a decade is only 10 years. Actual irl Phil has been alive over 3 decades. Did you mean centuries?

Yeah they are a least ancient but we really can't say how old they are though yeah Charlie would have been in one form or a other all the time.

@Aphlonwy Oop- My bad

You're good.
