Oh yeah, someone asked me for the age of each character, so I thought I'd post my response here for everyone to see... In case you're curious.
Now, obviously I can't count this up in human years... Different types of Pokémon have different lifespans, so it really wouldn't tell you much… And instead of forcing you to get out your calculator by making a "multiply by x.y" chart, I'll just show at what stage in life every character's currently at:
(Going from oldest to youngest, I.E Zerobi's somewhat older than Lucario, etc. Also, x/y means that they're the same age)
Gritania (Extremely long natural lifespan)
Mew (Extremely long natural lifespan)
Celebi (Extremely long natural lifespan)
If you just HAVE to know the specifics about a certain character, ask me. It's not like I'm NOT making this stuff up on the fly, after all.
