Lady Venus is a major antagonist from the videogame Pokémon Colosseum. She's one of the four Cipher Admins. She considers herself a pop idol and diva, which explains her rather eccentric style of clothing. She's dressed in layers of pink silk and carries a crescent moon on her back. She's obsessed with being popular and attractive. Some people dislike her for this, but the rest of The Under civilians consider her very beautiful.
Venus ruled over The Under in Orre. She became famous via a television show called "Under Time". Her catchphrase, "I'm your Venus!" made her a household name throughout the underground town. Venus soon became known as "Lady Venus". Most people loved her, although a few of the depth dwellers were highly annoyed with her shameless self-promotion and vanity.
Venus used the Under Subway to transport Shadow Pokémon from the Shadow Pokémon Laboratory to the Under. She then distributed some of the Shadow Pokémon in the Under Colosseum and passed the rest on to Miror B. and his associates.
After Dakim was defeated by Wes, the young ex-criminal used the elevator in Miror B.'s hideout to access the Under. Venus, hearing about the defeat of her colleague, used her television program to control the citizens with propaganda. She informed the people of the Under that a spy had invaded, and ordered them to capture him on sight.
The inhabitants of the Under failed to recognize Wes and Rui as spies - thinking that they were members of the Under as well.
However, Silva arrived in the Under, following the trail left by Cipher. He was immediately captured and locked up when he was mistaken as Wes.
Wes stormed the Under's TV Studio and confronted Venus in a Pokémon battle on live television, optionally snagging her Shadow Suicune. Venus was defeated and she fled into the Under Subway. She lured Wes and Rui into Cipher's train, the Shadow Liner, and made an escape while the two young heroes were distracted. Unfortunately for her, she dropped the key to the Shadow Liner while she was running.
Venus doesn't reappear until Realgam Tower was completed. The pink diva had one of the keys needed to unlock the tower itself, and guarded it in the maze that surrounded the tower. She once again was defeated by Wes, and surrendered the Blue ID Card to him.
Venus appears one final time in the Deep Colosseum.
