Melony

Melony is a minor character who is the sibling of Mango. She plays a minor role in both Pokémon J and M.

Description
'Melony is a young, sweet female who is the main sibling of Mango. She really hopes to be like her big sister and become a better trainer herself.'

Pokémon
Melony is not old enough to be a Pokémon trainer, but Mango lets her use her Gastly as a partner.

She is later seen to have a Pokémon when Mango returns to celebrate Melony's birthday, which was a Voltorb.

Note: Her Voltorb (like Mango's Electrode) is a special Voltorb, since it resembles a watermelon fruit.
