Projects MANTIS (Massively Augmented Neo-Tech Integrated Soldiers) was one of the many projects undertaken by MOTH to defeat the Honkai. The project involved extracting the DNA of emperor-class Honkai beasts and inserting them into human soldiers using ICHOR (Intra-Chromosomal Honkai Gene Repeats) to grant them superhuman abilities and innate Honkai resistance. The project was successful, and produced at least 13 known MANTISes.
The Active Honkai Reaction,[lower-alpha 1] is the final form of the MANTISes that can be manually activated and fully turns them into their Honkai Beasts. All MANTISes have a natural instinct to activate it and have to be actively suppressing it. Dr. Mobius is known to have activated this form (with her sim being able to access less powerful version), and Kevin said if he were to unleash his, the world would end.
