Also known as: デイノニクス11兄弟
Inhabitants of Fate/Grand Order's South American Lostbelt. There are 11 "brothers", which are all members of the Dinosaur-like Deinos race and look like deinonychus wearing ornaments, with only three different designs. They aren't referred to with individual names in the story, but as "Deinonychus Brothers 11", despite that, as a joke, not all of them are necessarily present at all times and they aren't strictly biological siblings.
They have a xokta (soccer) team named Death Rolling.
