Dendra is just as naughty as her other ghost pokemon, but she knows how to avoid getting caught, and often pins the blame on Umbra. This causes a lot of fighting between the pair, out of sight of Hermione. In front of her, they present a united front, but behind the scenes is another story. Dendra and Umbra keep trying to one-up each other with their pranks, which sometimes get out of control.

Hermione received Dendra as an egg from Greg and Rose.
