Trish is the Devil May Cry series main female role, initially introduced in Devil May Cry. She also appears in Devil May Cry 2 as a playable character (where her appearance is a bonus feature and not a part of the game's plot) as well as in the PS2 version of Viewtiful Joe alongside Dante, and as a playable character in the PSP game Viewtiful Joe: Red Hot Rumble. She also appears in the anime version and in the Devil May Cry Volume 2 novel.
Trish is a devil who bears a great facial resemblance to Dante's deceased mother Eva, and is a creation of Mundus. As a result of her demonic nature she possesses several supernatural abilities, like superhuman strength and lightning powers. In the first game, she hires Dante to help stop Mundus's plan to conquer the human world by opening a gate to the demon world on Mallet Island. Later in the game Dante learns that she is a servant of Mundus, and that her resemblance to Eva is part of a plan to lure Dante to the island so that Mundus' servants can kill him. However, she develops feelings for Dante and helps him defeat Mundus. In the game's epilogue, she and Dante are shown working together as partners out of the renamed "Devil May Cry" office.
In the anime, she has since gone solo but sometimes reappears to work with Dante, who has given her an open invitation to come back at any time. Trish reappears in Devil May Cry 4 partnering with Dante once again. She disguises herself as Gloria, an executive of the Holy Knights. She reaches this high position shortly after joining the cult by presenting Sanctus with the Sparda sword, for which some members appear to be suspicious of her. She eventually reveals her identity when Sanctus attempts to complete a demonic structure known as the "Savior". Trish is voiced by Sarah Lafleur in Devil May Cry, Danielle Burgio in the fourth installment and by Atsuko Tanaka (Japanese) and Luci Christian (English) in the anime.
Trish appears in the crossover fighting game Marvel vs. Capcom 3: Fate of Two Worlds for the second time as a playable character since Devil May Cry 2. She uses the Sparda sword and her lightning abilities to fight like in Devil May Cry 2.
