On the PlatinumGames development blog, Bayonetta 2 director Yusuke Hashimoto provides a look at some of the new demon enemies in the game.
“Unlike the strict hierarchical structure of the angels, demons subsist in a brutal dog-eat-dog world,” Hashimoto writes. “For their appearance, I tried to avoid the cliché sinister look and go for something more inorganic, almost robotic.”
The demon you see above is named “Hideous”. Hashimoto describes it thusly: “Its appearance evokes a feeling of ‘hatred given form’. I designed it as a beast that prowls around Inferno, looking for prey.”
“Unlike its angelic counterpart Acceptance (centaur), I feel like the design for this one came together (relatively) quickly.”
