Taizosu Dartan

Taizosu "Cannon-1" Dartan is the robotic guardian built by Kayleen Evanston while attending  MCLT-2 (Madam Curie Tech in Lunar-2). He was built after L.I.A gave her permission. Knowing the family's enemies, the current SECAI andoid models weren't sufficient.

In his lifetime leading up to his sacrificial death along with Mariana a few years after Kayla's MCLT-2 graduation,  He successfully stopped a plot by Kayla's arch rival Lina Vera and her robot Fractura. The plot was a conspiracy involving the complete shutdown of all MCLT schools by high school drop out and future Lunar-2 slumlord, Cecil Kunzleman. Taizosu was on guard duty in MCLT-2 when a virus known as "Xyril" was uploaded to the mainframe. Prior to the outbreak, he was connected to the mainframe via fiber obtics for MCLT-2's maintenance.

He spent weeks battling infected SECAI within the school's vast holographic cooridors and non-digital classrooms alike. Fractura, a robot made by Lina Vera, was the "Watchbot" in making sure the revolution wasn't interrupted. In her few incarnations (Fractura V2 and X-Break), the droid couldn't defeat Taizosu and his array of military grade holographic weaponry.

Kayleen has often referred to Taizosu as her son.
