There's the Platinum Edition Dinobot set that has the AOE Dinobots in the G1 colors along with G1 accurate heads if that interests you.
I can't remember what GDO stood for either (Global Development something, I think) but it was the Toys-R-Us exclusive sub-line in Generations with the old red-background packaging. About fifteen toys across the major size classes, but the ones I listed were really the only ones that fit your criteria. There was a Powerdive remolded from HFTD Highbrow that homaged G2 Powerdive, though. EDIT: there were also a ROTF Skystalker redeco called Laserbeak and a HFTD Breacher redeco called Brawl, but those were really on the periphery of being acceptable G1 homages (in my opinion).
There is a version of that which has the same G1 color scheme but with a new G1 styled head sculpt and he's part of a set that has the same thing happened to them. Here's a thread showcasing them. Dinobots Platinum Edition set
yep I am aware of them. I like the sdcc set for the beast mode I think it is more g1 accurate and I like the platinum head in robot mode thinking about doing some parts swapping
There's also a G1-inspired Wheeljack remold of the DOTM Que figure. Takara put it out in their Movie Advanced line. Hasbro didn't release it at all.
I saw that but don't like the car. What about him? The original toy is a jet/space ship the rift toy is a truck. Head sculpt only rhing that carried over
Whether it's a decent homage to Pipes is highly debatable (and the person arguing in favor is likely to lose, to be honest). But that said, that mold was a standout of the first movie line, in my opinion. One of the best.
blowpipe could also make a pretty alright soundwave, if you don't mind him having a truck mode. yeah, there's already a movie soundwave, but this one still has a general G1-ish SW headsculpt, the blue is a perfect match and he has a window chest...
i'm starting to love this figure. reprolabels has some stickers that bring a little more of the g1 elemets into it Labels for 2007 Rescue Ratchet
Off the top of my head here is everything that is G1 inspired from the first movie - Movie 1 Deluxe Target exclusive G1 colored Starscream - Movie 1 Deluxe Target exclusive G1 colored Jazz - Movie 1 Voyager Rescue Ratchet - Movie 1 Voyager Thundercracker - Allspark Power Voyager First Strike Optimus Prime - Allspark Power Deluxe Jungle Bonecrusher - Allspark Power Deluxe Cliffjumper
does anyone have the voyager ratchet and the evasion optimus prime? i would like to see a picture to judge the scales of the figures. right now i'm thinking about the tf deluxe ratchet for the hunt for the decepticons series
