Eva is Princess Ava 's evil twin sister. Jealous of Ava's position of power, she hatches a plan to steal the Friendship Heart while her sister is busy with the Friendship Ceremony. She ends up breaking the Friendship Heart in two and accidentally sending Ava to the Big City. She escapes capture with one half of the jewel, leaving the other half in the heroes' paws.
Determined to become the next Princess of Pocketille, she does everything she can to recover that half and keep Kate, Magic, and the Royal Guards from bringing Ava back. As fate would have it, however, this dark obsession leads to her end as the Petbuster's prisoner.
After "The Homecoming"
Many months after Ava returned home to Pocketville, Eva remains imprisoned in the Petbuster's house. Just after she is sold in an auction, she scratches her would-be owner and escapes. She manages to find Krakia, who still has the Communication Shell, and contacts Zull and Gort.
The pitbulls, still terrified of Eva, agree to help Eva get back to Pocketville with Durillia's help. Once back, Eva meets Willis and takes a liking to his rude attitude toward William and the other Royal Guards. She ends up developing a crush on him.
Shortly after Milo's arrival in Pocketville, Eva finds out he has a secret crush on her. She tries to continue to act normally around him, but eventually, she begins to like him as well. Whenever Milo goes anywhere, Eva sends Krakia to spy on him because she fears he's cheating on her behind her back.
A few months later, Willis' behaviour imrpoves thanks to Bella's class, much to Eva's hidden chagrin. However, she soon finds out that he's only acting that way because he likes Bella. Eva pretends not to be angry, but it isn't long before Willis is ignoring her completely.
One day, Eva sings an evil song around the Crystal Heart, which makes Cadance and Milo begin to suspect her of evil intent. Later, Eva learns that Milo secretly isn't sure he's capable of protecting the Crystal Heart and decides to help him get more confident via tough love. She begins belittling and taunting him, saying he doesn't have the guts to hold his position and someone could take the Heart right from under his nose. This creates distance between them, but it also makes Milo all too ready to defend himself and his inanimate charge.
After a month of this, Milo starts accusing Eva of going back to her evil ways. Offended, she tells him about her plan, how she knows it worked, and then runs off, leaving him feeling rotten. She goes to Willis for comfort and says she never wants to be with Milo again.
