These are my 2015 SDCC exclusives photos, which includes the Fembots, Devastator and Kreo set, as it's unlikely that the Devastator or Kreo sets will spawn their own separate review topic. (and it would be off-topic posting all of these in the Fembot 3-pack review)

Boxes.


Devastator first.


Vehicle modes with the regular versions in robot mode.


Comparison in robot mode (regular on left, SDCC on right).


Comparison of vehicle modes (regular on left, SDCC on right).


Combined mode comparison, with Gen1 (reissue) & Actionmaster.


Combiner Hunters 3-pack.


The only photo I have of them out of packaging at this time. Since there is already a review topic and comparisons, I probably won't bother doing my own.


Kreo set.


Comparison with last year's Kreo set.

This year's set has metallic shiny lettering and character art, so it looks darker at this angle.

The "artefacts" of this year's set... with some things that appear to homage Back to the Future and Goonies.


And the "artefacts" from last year's set for comparison.
