To combat Vita, the Professor created Clone Abby, a clone of the Rebel Army's Abigail. To ensure unwavering loyalty from the clone, the Professor removed its ability to feel emotions. To test out the clone's abilities, the Professor sent Clone Abby to attack a Rebel engineering facility where the new Emain Macha twins were being manufactured. After the clone delivered heavy damage to the Drache Macha, the Professor announced to Abigail that he would improve on her clone before having Clone Abby it depart.

However, after Clone Betty is hacked by White Baby, the Professor has the group fall back and locks Clone Betty into failsafe mode before removing the virus from it.
The Professor contacts the Regular Army to inform them of a brainwashing treasure that is causing everyone to go on a rampage. The Regular Army eventually neutralize the signal and he is impressed with their actions, stating that he obtained a lot of information despite being a spectator.

After the two return with the materials needed, the Professor congratulates the two for their successful mission and pats them on the head.

When Clone Betty returns, having been defeated by Alma, he reassures it and states that it managed to obtain an acceptable amount of information.

Following his apparent death, a clone of the Professor in a golden Ring Laser Mecha, led a series of attacks on military installations across the world.
Returning to Earth for Christmas, Percier and Marty make a wish to see the Professor again. Later, after having her Hodumi++ destroyed by Teleko and being left in the middle of a blizzard, Chloe comes across a silver-haired child with a high resemblance to the Professor in the distance.
The Professor unleashed a "boreal matter" on the inhabitants of an island, causing them to become more aggressive. He was eventually confronted by Odette and Nova, who were investigating the source of the "boreal matter", and fights them with Rugname X. He eventually tells them that the "boreal matter" is only temporary and will soon wear off before departing. Nova attempts to go after him but is held back by Odette.
