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.

Boss
Boss (ボス) is an uniquely large beetle from the Little East Blue Arc. He was originally a creation of Dr. Indigo, but escaped.

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.

Screen Buffalo
The Screen Buffalo (スクリーンバッファロー) is a giant carnivorous buffalo with a giant beard. A predator lurking in the snow, this horned beast blends into snow fields' scenery. Its attacks its prey by closing in without being noticed.

Jura Chou
The Jura Chou (ジュラ鳥) is a bird that resembles an archaeopteryx. Its overall color is green, while the feathers on its wings are multicolored. Its head is black, and doesn't seem to have flesh or feathers. For his giant size and flying capabilities, it can hunt enemies in the air easily. When the creatures from Merveille are summoned to the main island, one is seen invading Shiki's palace. Later, another one is seen trying to eat Luffy and Billy as they fight Shiki.

Kaen Kabuto
The Kaen Kabuto (カエンカブト) is a giant black beetle, looking like a mixture of many beetle species. It has pink fur around its body, and four horns. It can use heat to breath fire, using it against enemies. It attempted to attack Sanji and Usopp, but it was defeated. Boss may be a Kaen Kabuto.

Shimatori
The Shimatori (シマトリ) is a strong four-winged, savage, and mysterious bird. It dishes out powerful strikes with its four wings, and it swoops down on its unfortunate prey. Its name comes from the Japanese words "shima" (縞) which means stripes, and "tori" (鳥) which means bird.

Giragon
The Giragon is a green giraffe with black hair on its neck and a long neck which can twist. Its name is a combination of "giraffe" and "dragon" since it has a long dragon-like neck.

Oh Imomushi
The Oh Imomushi (大イモ虫) is a giant caterpillar seen chasing Sanji and Usopp on an island on Merville, but it fell off the island.

Toramata
A Toramata (トラマタ) is a large blue six-legged tiger with two tails and long teeth like a saber-toothed tiger. Its design and name is a reference to the Japanese mythological monster called a "Nekomata" (猫又), which translates the Toramata's name to "Forked Tiger" (虎又). It was sleeping in a tree, but is awakened by Sanji and Usopp, and later is defeated by the pirates.

Cowball
The Cowball (カウボール) is a small bull-like creature. His skin, fur and eyes are red colored, while his horns are pink. Even being small, his body is very large in comparison to his hooves, still, he can launch himself in high speed, resembling a bullet being shot from a gun. It tried to attack Sanji and Usopp; though they weren't defeated, they broke the ground below the pirates, making them fall.

Ettousaurus
The Ettousaurus (エットウザウルス) is a dinosaur-like creature that lives in snowy places. It's overall color is cyan, with some black spots, has white fur over his back, tail, around his head and under its mouth. It also has large antlers. It was seen attacking a giant snake, Dasoku, and then trying to attack a little girl, but it was defeated by Zoro. Two other Ettosaurus are seen running to the main island of Merveille.

Dasoku
The Dasoku (ダソク), also known as a Mukade Hebi (ムカデ蛇) is cross between a snake and a centipede, and is large and lengthy. "Dasoku" (だそく) means superfluity. If separated, it literally means "snake feet" (蛇足). It was being attacked by an Ettousaurus.
