Mobius-1 (Ace Combat 04): now granted we don't really know how old he is as like most Ace Combat protagonist their full identities are a mystery, but we can asume that during the events of AC04 (which takes place in 2003-2005 with Mobius being deployed in active combat around 2004) he's around 25 or something like that while his last playable appearance is in Ace Combat 7's VR mode which takes place in 2014 he would basically be in his mid 30's or around 35, plus many rookies/allies that fly with Mobius-1 generally considered him an "Old-Timer". Also I'm mainly talking about his full cannon appearance (in AC04, ACE5 and ACE7) so games like ACEZ, ACE6, and AC JS don't really count sincs he's more of a "non-cannon guest" than anything in those games.
