bitBeast
All the main Beybladers have a special beast with amazing powers locked up inside the BitChip which sits atop each of their Beyblades. The BitBeasts are called upon in battle to attack with their own special attacks and elements.

Venus aka ビーナス is Ming Ming's BitBeast. She white with a pair of green eyes, and the body of a feline or K9 with a wolf-like tail, two sets of wings and the head resembles a cross between a bird and a hound. When the attack Venus Temptation is called upon the surroundings change to a pristine meadow filled with flowers and animals, then Venus appears from the sky to attack the foe.

Like all Justice 5's BitBeasts, Venus is named after the Roman Goddess. She's the goddess of love, beauty and sex. Ming Ming just seems to be the love, beauty and sex within her team and expresses it enough through her personality and style. Either that or it's because Venus is the most popular Goddess for the only girl in the team's BitBeast to associate with.
