"Isabella Valentine (イザベラ・バレンタイン, Izabera Barentain), commonly called Ivy (アイヴィー, Aivī), is a fictional character in the Soul series of video games. Created by Namco's Project Soul division, she first appeared in the original Soulcalibur and its subsequent sequels, later appearing in various merchandise related to the series. She was voiced in Japanese by Yumi Tōma until replaced by Kanako Tōjo starting with Soulcalibur Legends; in English, she was voiced by Renee Hewitt in Soulcalibur II and Lani Minella for the remainder of the series.
The illegitimate daughter of undead pirate Cervantes de Leon, Ivy was raised by a noble family until her father became obsessed with the cursed sword, Soul Edge, leading to his death and later her mother's. Desiring to destroy the sword, she creates a segmented, animated blade, only to become Soul Edge's pawn and learn that it intends to use her as its next host. After an attack by Cervantes results in the loss of her soul, Ivy uses a temporary artificial one to keep herself alive, and continues after the blade.
Since her introduction, Ivy has been well received, considered both an attractive and strong female character by various sources, and called one of the most beautiful female characters in video games by sources such as IGN. She's also been featured on various top ten lists regarding either subject such as Spike TV and Team Xbox, as well as G4tv's Video Game Vixens. Scholastic studies have examined the character in the context of the series and video games in general, as well as when compared to other video game related sex symbols such as Lara Croft. Her role as a sex symbol has also been discussed by said sources and the media. Some, such as MSNBC, argue that her appearance goes "too far", while others such as The Escapist feel it helps to define her character."
