Adamantoise from FFXI
The Adamantoise, sometimes simply named Land Turtle, is a large tortoise. Its shell provides it with a strong defense to its body. Its name is a portmanteau of the words tortoise and adamant, referring to the resistant material composing its shell. The Adamantoise is often explicitly related to Adamantite, one of the strongest metal in several games of the series, which is used to make strong weapons such as Final Fantasy I's Excalibur. Traditionally the Adamantoise is a mid to high level solitary monster appearing on beaches or in the final dungeon. The Adamantoise and sometimes other variously named turtle monsters have appeared in all numbered installments of the series except the first, in addition to Mystic Quest, Tactics Advance, Chocobo's Dungeon 2 and Final Fantasy Fables: Chocobo Tales. They also appear in Itadaki Street Portable, and are featured as a Gummi Ship model in Kingdom Hearts. Other names include Adamantaimai, Adamantortoise, Grass Turtle, Land Turtle, Tortoise, Carapace, Turtle, etc.
