Animal Species/Strong World

Shiki, in his attempt to take over the world and destroy East Blue, had Dr. Indigo create an army of mutant animals with the drug SIQ. Most of these animals appeared in the tenth movie.

Billy
Billy (ビリー) is a giant electricity producing bird from the tenth One Piece movie. He was originally a creation of Dr. Indigo, but he aids Luffy in fighting against Shiki in the air.

Land Gator
The Land Gator (ランドゲーター) is an enormous alligator as flat as land mass hence its name. Its flat headed design slightly resembles that of a Japanese mythological monster called a Waniguchi.

Mori Dako
The Mori Dako (森ダコ) is the tyrant of the forest. This horrible octopus-like creature comes kicking through trees. Using its said countless legs (though the actual number is twenty) it is sure to catch its targeted prey. The Mori Dako was first seen in One Piece Film: Strong World. It quickly disposed of a Land Gator that was chasing Luffy. It then decided to target Luffy but was soon defeated by Don Kamakiriri.

He makes an appearance in the cover of Chapter 590, along with Jinbe and Dracule Mihawk.

Don Kamikiriri
Don Kamakiriri (ドン・カマキリリ) is a looming wicked cutter. He is dangerous, as he is always angry. He has extraordinary arm scythes, these fearful blades can cut and tear through nearly anything, demonstrated by cutting through solid stone with extreme ease. He quickly defeated a Mori Dako that was chasing Luffy. It, however, was soon defeated by a Terror Guma.

Terror Guma
The Terror Guma (テログマ), also known as the Long-armed Bear (手長グマ), is a black bear with white stripes on its body and long arms, like prisoner uniform. The most notable feature of the Terror Guma is its all crushing strong arms. Using these very long arms its strikes are very likely to result in a killing blow. Its cute round eyes are quite deceiving of this creature's violent nature. It defeated Don Kamakiriri before turning on, and ultimately being defeated, by Luffy.

Guma comes from the Japanese word Kuma くま/熊. The Terror Guma, being a bear with long arms, is similar to gibbons, in Japan called "Long-armed Monkeys" (手長猿) being apes with long arms as well.

Guntai Ari
The Guntai Ari (軍隊アリ), are a group of soldier-like ants. Using numbers to take down even enormous prey, they are always acting in a group. If they spot prey they will reducing it to bones in an instant. However, if their target has already been reduced to bones, then they will simply march through it harmlessly (as was in the case of Brook). They attempted to attack Brook, Robin and Franky, but they spot a Baku Zame and kill it. They try to attack the pirates again, but are defeated by Brook (who is somewhat offended when Franky surmised the reason as to why the ants left him safely alone was because they already thought of the living skeleton as "leftovers").

Baku Zame
The Baku Zame (バクザメ) is a shark that is as long as a serpent. It is green with six pectoral fins, three sets of gills, and two dorsal fins. It attacked Franky, Robin and Brook, but got eaten by Guntai Ari.
