Viri Melissa

Viri Melissa is a vendor NPC in Plants vs. Zombies: Infinite Generation and the young, energetic captain of LEAF's scouting department. She serves as the primary quest-giver for most of the first campaign if the player is an Eclipse Phase user, and continues to provide relevant equipment throughout the player's journey.

In combat, Viri is one of several Riders who uses a Core Gundam and the Mega Ulorder to don the Marsfour armor, an equipment set focused on high-speed CQC tactics. Not wanting to feel left behind with her friends and fellow commanders, she later completes the Gaia Heart armor to achieve compatibility with the Core II while still retaining her combat style.

While Viri spends more time away from home base off-screen compared to the other commanders, The Dark Mirror marks a spike in her activity on the field nonetheless, having formed a bitter rivalry with her counterpart, Pyre.

Origins
Viri is an Enlighten-Mint, and is therefore based on the Lamiaceae family, also known as mints. Her last name is derived from the Melissa genus of mints, for its similarity to the body of Enlighten-Mints.

Personality
Viri is energetic yet laid-back, showing off her youth (comparable to some of LEAF's younger agents) and befitting of her role as LEAF's chief exploration captain. Though she frequently cracks wise about matters and messes around in fieldwork, she is nonetheless fully dedicated to her job and has the leadership qualities to show it.

However, Viri's youth also makes her unaware of certain parts of reality, such as the harsh, unfair truth of Marius's past, to the point where she refuses to accept it and (unsuccessfully) battles him in the Gaia Heart armor out of the mistaken belief that as a friend, she is convincing him not to go down a dangerous road.

Gameplay
Viri is normally found next to a screen full of maps in the main Multi-U wing of the LEAF-Prime Headquarters. Like the other commanders, Viri will sometimes leave her post for story-related events.

Vendor Inventory
Viri sells first-party armor sets for Eclipse Phase users, and also provides certain quests such as campaign steps.

In combat
Viri appears as an allied combatant in some stages. She is functionally identical to an Eclipse Phase using the Voltrazor subclass, with the primary exception being that all of her abilities have red visuals instead of blue, and the Sparking Bolide is replaced with combining the Marsfour's Slash Blades and overclocking the integrated beam generators. Once Viri begins using the Gaia Heart armor, all of her attacks become gold in appearance and can alternate between electric and heat damage.

Core Gundam
Viri uses a Core Gundam, painted red to match the Marsfour armor, and armed with a basic rifle plus two sabers. Having grown accustomed to the Marsfour's weapons and combat style, she did not upgrade to a Core II when Marius and Adans did, noting the lack of proper high-speed melee options with its available configurations.

A Mega Ulorder is attached to the wrist in a similar manner to the military method of wearing a watch (worn upside-down), enabling its user to insert data cores and call down armor packs for the Core.

Marsfour Armor
"Eyes up, commander! Run through, like lightning!"

- Transformation announcement for the Mars data core in the Mega Ulorder The Marsfour armor is one of the nine original armor configurations developed for the Core Gundam and Core Gundam II. It is a red, lightweight suit of powered armor equipped with numerous swords, claws, and boosters that enable Viri to move at blinding speeds and perform sudden strikes.

By default, the Marsfour's primary weapon consists of the Slash Blades, physical swords with integrated beam generators. This enables the blades to break through both kinetic and energy shielding, and also gives Viri a viable ranged option in combat by discharging the projected beam coating and sending it flying at enemies.

Core Gundam II
In an attempt to stop and "save" Marius from himself, Viri activates a spare Core Gundam II and takes the Gaia Heart data core with her. After being successfully convinced to stand down, both the Core II and the Gaia Heart armor become her new arsenal (but not before both of them were reprimanded for overstepping their boundaries as leaders and going on unauthorized missions.)

Gaia Heart Armor
"Eyes up, commander! By the light of our bonds, let me write up your sins!"

- Transformation announcement for the Gaia Heart core in the Mega Ulorder The Gaia Heart armor is a golden extra configuration for the Core Gundam II, created out of Viri's lingering desire to catch up to the other two primary LEAF-Prime commanders. Although it was left dormant due to not having an apparent need to replace the Marsfour armor, Viri activates it anyway out of her misguided beliefs about Marius.

In this form, Viri retains all of her original equipment and abilities from the Marsfour, with their output/sharpness and the Marsfour's top speed greatly upgraded. Additionally, beam reflectors are stored in the shins and wrists of the armor, enabling Viri to perform crippling kicks and punches in lieu of a sword.

Trivia

 * Viri's involvement in the Rebirth Under a Spectre arc is analogous to Alain's fight against Makoto Fukami in Kamen Rider Ghost REBIRTH: Kamen Rider Spectre, but with the moral grounds flipped (i.e. instead of Makoto needing to be saved from himself by Alain, Marius is in no such position, with Viri only believing he needs to be.)
 * As an extension of the parallels, Viri deploys the Gaia Heart armor for the first time in this fight, similarly to how Alain's Necrom Eyecon is permanently upgraded into the Yuujou/Friendship Burst Eyecon.
