Describe the character of Thomas Marvel.

Thomas Marvel is a tramp who becomes the unwilling accomplice of the evil Griffin. Though possessed with remarkable powers, Griffin needs someone to help him carry out his wicked plans for world domination and mass murder. Griffin first stumbles across Marvel on a remote country lane. He appears to have all the qualities Griffin seeks in a sidekick: gullibility, suggestibility, and not much in the way of intellectual curiosity.
But what Marvel lacks in intellect he more than makes up for in street smarts. (With Griffin it's almost the other way round.) He may have a seemingly chronic aversion to hard work, but he understands the value of money, and being Griffin's sidekick does allow him to lay his hands on lots of lovely green stuff. Thanks to his association with Griffin, Marvel's able to rise up in the world, using his ill-gotten gains to buy himself an inn. (Called "The Invisible Man," no less.) Marvel's bizarre little adventure with the Invisible Man has been truly transformative for his character, turning him from an ignorant, work-shy layabout into a pillar of the local community.

Thomas Marvel in H. G. Wells's The Invisible Man is the first accomplice to the Invisible Man, although a rather unwilling one at that. Although Marvel can be initially deemed "shady" by all accounts, his character does not remain static but actually transforms over the course of the novel, going from being a homeless tramp (chapter 9) to successfully running his own inn off the money he keeps from Griffins. Initially a rather predictable character, Marvel can be described as lazy, immoral, and unintelligent at the beginning of the story. However, specific events could point to the contrary, such as when he seeks asylum with the police to escape Griffin (thereby displaying signs of morality) or the fact that he's kept Griffin's notes safe, seemingly aware of their value despite being unable to comprehend them (thereby showing signs of intelligence). Furthermore, successfully running his own inn is a statement in and of itself about his initial laziness!
