The Cavalier

History
Mortimer Drake was a man of exotic and idiosyncratic taste. When he found himself unable to purchase more exotic valuables for his collection legally, he resorted to theft. Donning a costume resembling that of a Musketeer, he called himself the Cavalier. His course of actions ultimately brought him into conflict with Batman and Robin. Drake matched wits against Batman and Robin several times, and escaped them in each encounter, but Batman was able to deduce the Cavalier's identity, leading to Drake's eventual imprisonment.

In Batman Family #10, Batgirl and Batwoman teamed up to defeat the Cavalier. Cavalier couldn't find a way around his code, which prevented hitting females, but after a self-examination he concludes “the devil with gallantry” and hit Batgirl with his fist.

A few issues later in Batman Family #15,[3] Killer Moth bet Cavalier that he could find the way into the Batcave from Batgirl before the Cavalier could get it off of Robin. While Killer Moth was led to a fake cave, Cavalier was shown a large nest, to which the Cavalier came to the conclusion that Robin was an alien bird life form.

Cavalier appeared in Justice League Of America #44 as part of a group of supervillain drinking buddies who were trying to regain their lost items of power. He was defeated by Blue Beetle who clotheslined him in an alleyway.

In recent years, Cavalier has become insane and is kept in Arkham Asylum. During Knightfall, he faced Batman once again but was defeated with ease. It remains to be seen how Drake became insane, or if his origin has changed because of the first crisis. One Year Later, he appears in Justice League of America #2 as an informant for Black Lightning. According to Black Lightning, the Cavalier is in a closeted gay relationship with Captain Stingaree.
