Mystery Dungeon: Shiren the Wanderer 3's setting, the Clockwork Palace, has given developer Chunsoft license to pit Shiren against some supremely freaky-looking mechanical monsters. Just the very existence of monsters in a Mystery Dungeon game is cause enough for fear, as any single one of them can kill you and erase all your progress. It almost seems like overkill, then, to design enemies that actually look creepy at all.
Famitsu has revealed some of the boss creatures found in the dungeon, including the five Ikusa Oni, a sort of Power Rangers-type organization, but made of monstrous samurai, and the Clockwork Kasha, a flaming cart with a Noh mask.
The Clockwork Giants aren't particularly frightening, but they're certainly weird. Both are mechanical heads with one pair of appendages each; one has hands and the other feet, and both have totally metal eyebrows.
