She is voiced by Kari Wahlgren in the English version of Uprising, and by Stephanie Komure in Super Smash Bros. for Nintendo 3DS/Wii U.
Phosphora is a blonde-haired girl with purple eyes, looking to be 16 or 17 years old and standing at around 5'7" (170 cm). She adorns a blue scarf that can conduct electricity, causing it to levitate and become rapturous when Phosphora harnesses electricity. She wears a small, black top ending at the midriff, overlapped by two white sashes, and white shorts. She wears open-toed boots made up of black wrappings and has a green-leaved vine wrapped around her body from her arm to her thigh.
Phosphora's personality is that of a stuck-up teenage girl. She can be quite rude to her opponents and seems to enjoy getting under their skin, such as when she flirts with Pit or points out Palutena's age. She can also be quite lazy, often passing off comments or events that don't concern her and handling almost everything with a nonchalant attitude. Despite these odd quirks, she is a fierce fighter and shows great ferocity in battle. She is very brave and always faces her enemies head on.
As her title implies, Phosphora has the power to manipulate electricity for a number of purposes. With this, she can turn into a bolt of lightning, move at incredible speeds, and teleport. Phosphora can fire bolts of electricity at opponents and electrify the air around her. Phosphora can also use her electrokinesis to create storms. However, if she expends energy too fast, she tires easily and must recharge.
