Spoiler Warning: Information regarding Trish that is not available until the end of the first game will be discussed here.
Trish is a female character in the video game Devil May Cry. Trish was created by Mundus to observe, and seduce, Dante. Trish was cloned as perfect resemblance to Dante's and Vergil's mother: Eva. In the end, she betrays Mundus to save Dante's life, proving she is more than just a soulless puppet. After their escape from Mallet Island, Trish becomes Dante's partner and sidekick in his devil hunting business.
Trish made an appearance in Devil May Cry 2 as a hidden character. Like Dante, Trish is armed with the twin pistols Luce & Ombra, she also wields the Sparda sword, which was given to her by Dante at the end of Devil May Cry. Since she is not actually a devil, Trish cannot use Devil Trigger powers, however, she is a demon, and can generate similar powers by tapping into her mystical aura.
