The only person who has gained anything from the invisible man was marvel explain how
Answers
Mr. Thomas Marvel was a short, fat tramp with a shabby hat, charity boots, battered clothes and homeless lifestyle. He did everything in a leisurely manner, meaning that he was lazy. Griffin makes him his accomplice, even though he himself considered him stupid and good-for-nothing, no one else being available. Marvel is basically a coward and is unable to stand up to Griffin. He becomes Griffin's partner in crime but cheats him ultimately.
Marvel is an opportunistic person. When he first gets a chance, he tries to sneak away from Griffin, but fails. The second time he manages to run away with all Griffin's money and his three books. Marvel, however is clever, because he gets himself arrested so that he can escape Griffin, who is after him. Moreover, he kept the three books for himself in the hope of solving their mystery, although this was an act of foolishness. Thus, he is the only one who benefits or gains from Griffin.
