The biggest changes of all occur in the functions that are also most important to monsters that get used during sex. It depends on the race and preferences of the monster that one is coupled with, but most men who become an incubus will have their penis grow larger by leaps and bounds, and they'll be able to please monsters even more. The amount of semen and spirit released from there will be incomparable to when they were human, and they'll have boundless stamina so that they're able to release it again and again without getting exhausted. <ref>[[Monster_Girl_Encyclopedia_World_Guide_I:_Fallen_Maidens#Monster_Transformation|''Fallen Maidens''; Monster Transformation Case Studies; 00 Incubus]]</ref>}}</div>
Besides genital gargantuism, incubi do not receive (permanent) drastic physical changes comparable to, say, an [[arachne]]'s abdomen or a [[succubus]]' wings and tail. They do, however, see disposal of features that impeded their sex lives previously, such as corpulence or the general frailties of old age.

There are changes ''under'' the skin for an incubus too. Stamina increases to monster-like levels as the power of mamono mana suffuses their body, and incubi gain some measure of the environmental resilience of their monster partner (e.g. heat resistance for a [[Lava Golem|lava golem]]'s mate, breathing underwater for a [[Sea Bishop]]'s mate, night vision for the mates of nocturnal or cave-dwelling monsters. Like a [[succubus]], they also gain the ability to actually ''sustain'' themselves on their partner's mamono mana in place of food.

An exception to the lack of drastic changes are the husbands of the various chaos/abyss-aligned monsters (such as atlach-nacha and mindflayer), which gain the ability to change into completely non-human or only vaguely humanoid forms. These forms can be reverted to normal human form at will, at least after the initial forced transformation, and thus are not considered a permanent transformation.
