Bentham was formerly an agent of Baroque Works with the alias Mr. 2 Bon Clay. He ate the Clone-Clone fruit, which allows him to mimic the physical appearance of another. Though initially an antagonist, he proves to be an ally of the Straw hats, helping Luffy escape on multiple occasions from the Marines. He currently is the Queen of Newkama Land in Impel Down.
In the 4Kids dub, he is voiced by Kevin Kolack. When FUNimation got the license, he is voiced by Barry Yandell. In a lesser known English dub by Odex, he is voiced by Dwayne Tan.
