In the digital world sometime you have to battle to defend yourself, the only problem with that, in Efoua case, is that the only artical of clothing baby digis must wear is their diaper and occasionally their battle gear (for those who have it at least) so if your someone who's embarrassed about being in only a diaper like her you're not gonna have an easy time battling.
i kinda hope one day somebody draws her trying to do a battle now that i think about it.
