Hecatonfoot (ヘカトンフット) is a kind of monster in The World R:2. The Hecatonfoot may look like a rhinoceros, but actually it is a turtle that had turned into a monster due to the Shadow. Its head is covered by a sturdy shell that has the power to pulverize trees or rocks with a single blow. Normally, Hecatonfoots are quite docile, but if attacked, they will retaliate and attack anything around them. Their rampages are very violent and too much for warriors with light armor and clerics.
