I've been thinking recently that there are a many examples of Transformers lore where I think one canon/continuity really stuffed up while another did it nearly perfectly.
For example, I love the idea of Pretenders in Masterforce. Like all good Transformers, they crash landed millions of years ago. Unlike most Autobots, the Cybertrons actually picked the dominant species correctly and disguised themselves as humans. They're immortal human-sized humans who've observed and interacted with us throughout history - absolutely fantastic. The Destrons made themselves look like horrible demons and scared us for a long while until they were imprisoned and then they escaped. They're all great - I love every one of the characters of the Masterforce Pretenders - they even make crap toys worth having.
On the other hand, the G1 comic - while my nostalgic favourite Transformers medium - completely dropped the ball on Pretenders. And then trampled it. A lot. The first Decepticon Pretenders were disguised as large monsters who then went and terrorised a bunch of humans. And, since - according to Scorponok - "these six warriors bear no resemblance to Decepticons, the Autobots will never suspect their true identities until it's too late!" Um... okay, but won't they still try to stop the rampaging giant monsters even if they don't realise they're really rampaging giant Decepticons disguised as rampaging giant monsters? The Autobot Pretenders were created because Optimus Prime's personality - still stored as... um... data on Ethan Zachary's 5 1/4" floppy disk - travelled through the internet and spied on the Decepticon Pretenders' creation (seriously, I couldn't make this stuff up if I tried). Now the Autobot Pretenders look like giant humans in armour. Bizarrely this does actually fool Scorponok and the Decepticon Pretenders... for about one page. The best thing about this first incarnation of comics Pretenders is that the execution was just so bizarre and camp that I got to read a story in which Skullgrin is a Hollywood movie star. Oh, and there was that story where Cloudburst just happened to find a planet of thirty-foot humanoids and almost got to make out with a hot alien chick until he blew it. (The second-generation comic Pretenders who show up have no origin, they just appear. Bludgeon? Longtooth? Thunderwing? Why are they Pretenders and when exactly did they get their shells?)
On the other hand, I think the comics were ingenious in addressing the Dinobots' creation - since there were no dinosaurs four million years ago, Shockwave crashed in the Savage Land (already a part of the Marvel Universe) and the Ark disguised five Autobots as the Savage Land's dominant species: dinosaurs. Simple and clever.
In the cartoon, however, Hound goes to a museum and brings back some tourist snaps:
WHEELJACK: If only we had some dinosaurs working for us. They'd really shake up the Decepticons.
RATCHET: Mmm. I'm with you, Wheeljack. We could build robot versions of those oversized iguanas -- if it was okay with Optimus Prime.
OPTIMUS PRIME: Robot dinosaurs might be useful. You have my authorisation.
What? That's it? Other than the fact that for some reason Prime's lines make me want to punch him or the scriptwriters in the face... the Autobots can just make Transformers now? Why don't they just make an army of them and... I don't know... actually beat the Decepticons?
The potential examples are endless - for me Primus is better than the Quintessons, Powermaster Prime is better than Ginrai, cartoon Headmaster Spike makes more sense than comics Headmaster Spike, 'The War Within' is better than 'War Dawn' and so on.
So I was wondering if anyone else thinks one continuity did something better than the others and why? (i.e. "X was just betterer" or "such-and-such-a-medium suxxors" will not suffice.)
