Giant Animals are a subcategory of the Beasts category, which includes ordinary animals that are not particularly intelligent or magical. However, unlike normal Beasts, Giant Animals are much larger in size and often more powerful. Giant Animals are standard animals but one or more size category larger. For example, a Giant Rat is a Medium beast, while a normal rat is a Tiny beast. A Giant Eagle is a Large beast, while a normal eagle is a Small beast.
Giant Animals can be encountered in various environments, such as forests, mountains, deserts, and oceans. Some of them are friendly or neutral to adventurers, while others are hostile or predatory. Giant Animals can be used as mounts, companions, allies, or enemies in D&D campaigns.
