7.1 Story
Once employed by the royal court, this self-proclaimed ‘super-great-hyper-genius’ professor was kicked out because of her sharp comments and uncompromising personality.

She prefers dangerous experiments and chemical explosions to cooperation, but she joined the party with the belief that there are things only she is capable of in the face of great danger.

7.3 Trivia, Spoilers & more
The name Mocha is likely referring to Caffè Mocha, a beverage made with Chocolate, Espresso and Hot Milk, as it explains why she created Espresso as her assistant.

She joins the team after clearing 6-1, where the “invulnerable monster that attack heroes for a set amount of time” condition is first introduced. This condition is quite simple to deal with if you have Mocha on your team, but impossible if you don’t. Fondue might be able to handle this condition, but it is inconsistent and risky since the position where the enemy will spawn is random, and if the enemy spawns in the middle of your team Fondue cannot do much about it.

Beside her skills, she does standard ranged damage and have 100% ATK damage per second after Ether Lv25, just like any other ranged heroes beside Ration, so she is not short in damage without use of a skill.

At later levels, the Ether Lv40 upgrades where it grant extra 2 sec duration to the taunt robot adds much needed reliability, since the lifetime of the invulnerable monster increases as levels get harder. Mocha has usage outside of this condition, which is in the Relic Site. She is the only method of taking aggro away from the mining machine and thus preserving its health. This can often safe you from the last wave, where you taunt all the rats and one ranged creature while focus fire and take out the other ranged creature.

After obtaining Rita’s Artifact for Mocha, she now offers some much appreciated extra damage, although her amazing crowd control ability is not amplified. This extra damage can be used in multiple ways, such as paring with Coq au Vin’s skill to take out melee minions that was previously too tanky to be one shot by her skills. For the most part, this Artifact is not a necessity so don’t worry too much about getting it early.

The Drone that follows Mocha by default is named Donut.

When you had Mocha's artifact, this can boost all party members for extra damage and def. It also can be affected by Flame spirit Stone. Giving more power as well.
