Designated Misogynistic Bastard

The Designated Misogynistic Bastard is a canon character in a Suefic who has been twisted by the Suethor into rejecting the Sue because she's female. The DMB's role is to make sexist comments, claim that the Sue is weak and inferior purely due to her extra X chromosome (rather than the fact that she is an idiot) and generally be a bastard. The Sue will eventually challenge him to a contest of some sort and best him before running into the arms of her Lust Object and gloating.

It is noted that there are very few canon characters in any 'verse who are actually misogynistic bastards. Their only purpose in fanfiction is to make the Sue look good.

A rather odd subgroup of DMBs are those that the Sues actually like or lust after. Apparently, some characters can't show they care about a daughter or lover without locking her in her room or generally bossing her around.
