The Generic Tree Ninjas are bear ninjas from Japan who work for The Dark Shadow Lord. They are Buddhist Monkey's original enemies, first appearing in Enter the Garden. They appeared in both of Buddhist Monkey's special episodes as the main antagonists, though in Three Courses of Death they were only minor villains. The Dark Shadow Lord kills the Generic Tree Ninja if they fail him as shown in Three Courses of Death.
In Buddhist Monkey's special episodes, they would appear in the middle of wherever Buddhist Monkey was meditating or reading to trash the place. They would continue to do this until Buddhist Monkey would snap and kill them. They reappeared in Buddhist Monkey (Ka-Pow! series), where they made a brief cameo at the beginning of Three Courses of Death where they again fought Buddhist Monkey. The last Ninja was killed by The Dark Shadow Lord for failing him. It is unknown if the Generic Tree Ninjas will return in future episodes or if The Dark Shadow Lord will use stronger warriors like Char Sui.
In Buddhist Monkey's specials, the ninja had insignias on their chests that related to the place they were attacking. In Enter the Garden they wore leaf insignias and in Books of Fury they had book insignias. In Three Courses of Death they had lily-pads on their heads. They were shown as ruthless, as one didn't care that he nearly killed Panda Mom, who was bystanding the incident. Like Buddhist Monkey, they have powers (e.g., teleportation, making duplicates of themselves, etc.) that they sometimes use in battle. They always attack in groups of three. Interestingly enough, they never seem to make any attempt to kill or physically harm Buddhist Monkey (even in self defense), only trash the area.
They also sometimes appear in regular episodes such as Keepin' it Reel and Blind Date, where they were briefly shown on a movie screen. The two special episodes are both movies inside the Happy Tree Friends Universe.
