Answer
The answer is a "stooge", which was the name given to Lord Tensai's attendant, Sakamoto. Bloom's portrayal of Tensai was heavily influenced by Japanese pop culture, specifically drawing inspiration from the exaggerated villainy of classic kabuki theater and popular anime and manga. This characterization often involved having a hapless assistant or "stooge" character by his side, who would be the victim of Tensai's wrath and comedic antics.
