By this, I mean, which characters would you say are on the older side (like Kup ) and which ones are on the younger side (like Bumblebee)? Compared to their troops, how old are Optimus Prime and Megatron? -All G1 continuities apply (comics, cartoons, Dreamwave, IDW, etc). -Characters from different mediums can fall in different places in the age range (e.g., Comic Shockwave might not be as old as Cartoon Shockwave relative to the rest of the cast). Here are my thoughts: -Kup and Ironhide are obviously amongst the oldest Autobots. Pointblank (the Targetmaster) is also described as an old veteran in his bio, so he's likely up there as well. Alpha Trion is even older. In the Marvel Comics, Emirate Xaaron is really old as well. -Hot Rod/Rodimus Prime and Bumblebee are just as obviously amongst the youngest. -Sideswipe and Sunstreaker seem like they're probably on the younger side. Bluestreak's probably not very old either. -I suspect that Marvel Comics Impactor is on the older side (and conversely, that his successor Springer is on the younger side). -Brawn, Huffer, and Gears seem like they might be on the older side (due in part to how their voices sound). -I think of Ratchet as older, but that might be partially because of his portrayals in Animated and Prime. -Optimus Prime is probably one of the older Autobots, but he's probably not as old relative to most of his troops as Megatron is. -Jazz is probably among the youngest of the Autobot officers and in the middle of the pack overall. Blaster's in the same boat. -Omega Supreme is almost certainly on the older side. -The Dinobots and Aerialbots are extremely young (in the cartoon; in the comics this doesn't apply). -Megatron, Soundwave, and Shockwave (especially in the cartoon) seem like they'd be amongst the oldest Decepticons. (All three appear in "War Dawn", for example.) In the cartoon, Blitzwing may be on the older side as well (since he semi-remembers the Quintessons). -Ravage, Laserbeak, and Buzzsaw seem likely to be older as well (especially Ravage in the Marvel Comics). -Starscream, in contrast, seems likely to be one of the younger Decepticons. Rumble and Frenzy are likely on the younger side as well (not because they're small, but because of the way the act like teenaged punks). -The Constructicons seem like they might be on the older side (since they were friends with Omega Supreme). -The Stunticons are very young.
