I really don't understand what this line is trying to do. G.I. Joe Ultimates don't quite cross the threshold of "worthwhile" for me personally, but I can at least understand their purpose and the justification for their existence. These have even more hurdles than G.I. Joe. They're a Transformers toy that doesn't transform. Ok, somewhat dubious, but certainly not unprecedented or out of the question. They're a Transformers toy that doesn't transform
and cost more than a Leader toy that does transform. Wait...what? They're renditions faithful to the cartoon. ...Ok...I don't really see a huge difference between "cartoon" G1 and "not cartoon" G1 designs unless you're trying to market "less detail" as a plus, but whatever... They're renditions faithful to the cartoon,
and depict characters/iterations that were never in the cartoon. Wait....huh? What is the point of that...
Seriously... take Wreck-Gar for instance. The Studio 86 version of him transforms, (in my opinion) looks better in bot mode,
and cost $25 less! What would be the rationale for buying this figure other than "it goes with the eclectic hodgepodge of overpriced non-transformers I have"?
[reads thread further]
Ok, well I guess that's one reason.

[Edit: ] BBTS list it as a "Toy Inspired Head" and a "Cartoon Inspired Head"
Man, that Joe line up seems way better than this Transformer line up to me...
To be fair to Tarn, though: I think he's a fine Transformer character, he just doesn't fit well in this line
at all in my opinion. If Hasbro ever did a Leader sized figure of him, I think that would be pretty cool.
