I’ll see your Rorschachzilla, and raise you a Grimschach.
Concept art for the 2007 live-action Transformers movie version of Bumblebee. I think these came from a DVD featurette. Personally, I like the unmasked head from the first sheet and the bug mask from the second the most of these, but the kitty mask look is certainly… interesting (as is the skullish look of the final sheet, for entirely different reasons).
On a personal note, the date in the corner tells me these designs were submitted on my birthday, assuming that’s December 7th and not July 12th.
Oh wow, the middle one. Bumblebee almost looked like that…almost wish he did. ALMOST.
