Markl is the tritagonist in the 2004 animated Studio Ghibli film, Howl's Moving Castle. He is the young apprentice of Master Howl, and he is also friends with Sophie. He is shown to know about certain things to do with the castle, including that Calcifer only obeys his master, with one exception: the black section of a wheel (which only Howl knows). Josh Hutcherson did his voice in the English dub.
Markl is quite short, with messy ginger hair and pale white skin. He is of an average build, and is often seen wearing a cloak, when in Howl's castle. This is because he uses it to disguise himself.
Markl is very obedient, doing what he is being told. He is also gives pointers to Sophie when she first arrived, making sure to keep her out of trouble. He was even called her a henchman of the Witch of the Waste. Sophie is patient with him. As the time pass, he likes her very much.
He is often plays with Heen and Turnip Head.
- In the original novel, Markl's name is Michael Fischer and he is 15 years old.
