Ive been a long term Pokemon fan since i first watched season 1 back in 98, i thought when the series went on he get older, but nope, 15 seasons (and about 16 years by the RL clock) hes still portrayed as a bloody 10 year old.
According to the Website Fanpop, they say he's 16 by now. - http://www.fanpop.com/clubs/ash-ketc...ow-old-ash-now
According to Wiki, Hes still listed as 10 - http://bulbapedia.bulbagarden.net/wiki/Ash_Ketchum
So i fail how the creators must get a kick with having him as 10 still
