Here are six interchangeable super-deformed mini action figures, based on monsters from Konami's 2008 Castlevania: Order of Ecclesia Nintendo DS video game (original Japanese title: "Akumajou Dorakyura Ubawareta Kokuin", and that translates to "Demon Castle Dracula: The Stolen Seal"). They're all made from the same basic "blank" body, which was then customized into each unique creature.
Design-wise, I was shooting for a fairly simplistic body type, similar to a papercraft or collectible vinyl figurine, that could be made, over-and-over again, relatively quickly. I looked at a variety of commercial products (Funko, Minimates, Gregory Horror Show, etc.), as well as the work of other artists, for inspiration. I made six toys total because that's a common number for a wave of action figures to have, plus it provides enough part variety to make the mix-and-match feature worthwhile.
Lined white paper, newsprint, cardboard, white glue, acrylic paint, ink, colored pencil, fishing line (Ladycat's whiskers only), and carpet fibers (Draculina's hair only).
While they all started out with the same measurements, the individual figures' widths and heights vary, largely due to projecting structures like the Ghoul's horn and Draculina's bat wings, so, rather than listing them all individually, I'll just give you the numbers for the "base" figure, before any alterations are made: 3.2 cm (1.3") wide x 3.7 cm (1.5") tall.
Each figure has three rotating pin-and-post joints, at the neck and shoulders, and Ladycat's tail also rotates where it joins her body.
Five days total: July 20, 21, 22, 24, and 28 (2014). Things started off with the construction of the Axe Knight on the 20th and 21st, Chosen Une came second, also on the 21st, Ladycat was modeled on the 21st and 22nd, followed by Draculina on the 22nd and 24th, and Grave Digger was also done on the 24th. After that whirlwind of activity, I took a break for a few days before finally returning to complete the project with the sixth, and final, figure, Ghoul, on the 28th.
