Role in the series
Escargoon has two distinct sides to his personality. There's the part of him that helps Dedede with his schemes and tricks, but he seems to have a genuinely nice side to him that only appears in extreme situations. Unlike most of the other residents of Cappy Town he does not dislike King Dedede, though the latter often whacks him with a mallet.
Escargoon's mannerism gives the impression of someone past his youth, and tends to get grumpy with the children of the village. He can be mean and naughty towards people in general, using his status as the King's assistant to lend him the right to boss people around or threaten them with the death penalty (in the Japanese version only). It is not clear whether he really is mean and only acts nice when he needs something, or if he has a good side of him that does not show because he is perpetually helping Dedede with his schemes in order to gain his approval. Since his mother says Escargoon is cowardly and would never hurt anyone, it would seem that the latter situation is more likely.
Escargoon can be cheerful and animated at times, and often does effeminate things such as wearing frilly aprons with hearts. (Other than that he rarely wears any articles of clothing, except an occasional bow tie, sun hat, or scarf in cold weather.) He is the usual host of Channel DDD for newscasts and special programs.
Escargoon is intelligent with a wide range of knowledge in botany (he wrote an encyclopedia on the subject called The Encyclopedia of Botanica), chemistry and electronics/robotics. When Dedede doesn't order something from Nightmare Enterprises, he tends to use one of Escargoon's inventions instead, such as a formula that turns things into monsters.The Empty Nest Mess He builds various machines such as a robotic grasshopper The Flower Plot, submarine A Fish Called Kine, missiles Cappy New Year, and even a robotic version of himself Right Hand Robot. Unlike King Dedede, he does not trust Customer Service, and rarely orders things from him.
He has a tendency to make comparisons and similes--for example, in Pink-Collar Blues, he compares asking the Waddle Dees a question to "interrogating a mime troupe."
