During her time at the Facility, Kimura eventually assumed the same abusive role as the people who victimized her in the past, particularly to Laura Kinney.

Laura tells Megan and Debbie to get her duffel bag and take what's absolutely needed and have 3 minutes to leave the house.

[7] When she arrives back at the Facility, she watches as they perform experiments on Mercury and eventually unleash their new creation Predator X upon the mutant Mammomax much to her pleasure.

Emma Frost detects her and telepathically subdues her, revealing Kimura's history of child abuse and neglect at the hands of her parents and peers.

Frost then mind-wipes her, making her forget about her grandmother—the only influential and positive person in her life—creating "a deep void that will cause [her] pain for a lifetime."

Frost then implants telepathic instructions in Kimura's mind to make her hunt down the Facility's leaders, particularly Professor Harkins, who oversaw Mercury's experimentation.

[9] After going through 6 months of getting her brain rewired to stop Frost's psychic command, Kimura begins selling clones of Predator X for the Facility.

Her brutality only seems to have increased as she cuts off Laura's arm with a small chainsaw for "being a bad girl" but X-23 then uses the trigger scent to her advantage and escapes with Agent Alisande Morales's help.

[20][21][22][23][24] Several publications, such as Screen Rant, Comic Book Resources, GamesRadar+ and PopMatters, have compared Kimura to Sabretooth, the archnemesis of Wolverine.

[29][30] Andy Kubai of Screen Rant has stated believing that the character would make an excellent adversary for X-23 in a film.

[31][32] Drew Kopp Comic Book Resources described Kimura as "a dark reflection of the person that Laura could have become if she allowed her desire for vengeance to consume her".
