Tatiana

Tatiana is the Union Negator 5 of Undead Unluck.

Appearance
Tatiana appears to be either a robot in the form of a black ball with a huge eye in the middle or an unseen person contained within the mechanical armor. She also has a robotic arm that shoots out its fist and can reshape itself to fire a laser.

Personality
Tatiana seems to care for her comrades, particularly Billy and Gina, and has a short temper when it comes to their lives.

Gina Arc
She was introduced sitting in seat number 5 and had been used as a ricochet for Billy's bullet to block Andy's Finger Bullets.

Spoil Arc
She shot her fist to hit Andy out of hatred for him killing Gina as she liked her. She was manipulated by Union Negator 1 to face her charging laser towards Billy whom she did not want to kill.

Abilities
Unnamed Negator Ability: Tatiana has an unknown Negator ability, however, It seems to have the ability to restore things, as she used it to fix a sliced hand the Andy cut when she punched him.

Laser: Tatiana can shoot a laser beam as she was shown to be unintentionally preparing to fire it at Billy when being put under Juiz's control.

Rocket Fist: Tatiana is able to launch her robotic arm's fist at great speed as she used it against Andy to punch him from across the table and into a wall.
