Battle penis
From Dopeymon
A battle penis is a special organ possessed by many types of Dopémon that enables even the females of certain species to use penis-based attacks, despite the fact that they don't have an actual penis.
Most battle penises are tentacle-like body parts that are usually hidden; this is the case with Dopémon such as Ballbasore and Ibesore, which have a long, thin battle penis hidden inside the bulb-like growths on their backs.
Other Dopémon--almost exclusively Dick-types--have penises in place of horns, claws, stingers, or some other body part. Though these types of battle penises are not as flexible and have shorter range, preventing the use of moves such as Penis Whip, they are also generally thicker and more powerful. Because of this, many Dopémon with horn-penises or arm-penises learn moves such as Dick Drill which require incredible strength and a penis that doesn't injure easily.
Occasionally, Urine-type Dopémon have battle penises; however, these are often fragile and rarely useful for Dick-type moves. In the case of Urine-type Dopémon, battle penises are mostly used to squirt sprays of pee at their enemies without exposing their vulnerable crotches to attacks.
