In Book 7 Ortho observes that, as something that exists outside of the natural world, his will cannot be overwritten by Malleus’ magic as long as the technomantic reactor that acts as his heart remains operational.
None of his gear works within Malleus’ domain, leading to his mother designing “anti-magical disaster gear” that specializes in “combat within areas affected by magic, and it can defend against system contamination caused by Malleus’s spell,” which she names the Cerberus Gear.
Based on a copy of Ortho’s schematics that Idia had saved to his lab computer, the gear was created in 48 hours by STYX’s tech development division. Ortho says that it has “exceptionally good energy circulation.”
The Cerberus gear is accompanied by two support droids on its first mission for use in exploration and combat, but the Chief Engineer warns that it can only operate within Malleus’ domain for 20 minutes.
Ortho is unable to wear any of the White Rabbit costumes provided by Deuce’s mother, saying that he would need proper machinery with a 3D printer.
Deuce takes him to a nearby blastcycle workshop and Ortho both designs and crafts his Rabbit Gear on his own, prioritizing “being as similar to the White Rabbit” as possible.
He still retains his vital signs scanning but replacing his antigravity component with the ability to walk, run and jump. He is also still capable of taking photos, but having removed his laser he breaks apart a sausage for the time into different pieces with his fingers, to their surprise.
After telling Epel that it is important to remain calm in emergencies Ortho becomes enraged at an insult to his Rabbit Gear, and making the bully regret his insult becomes his driving motivation for the Rabbit Run race during the White Rabbit Fes event.
Having removed his the gear’s flight capability he jumps out of a trap that he gets knocked into by another bully, resulting in a crack to the gear’s exterior casing: “I didn’t have time to let it properly set after casting the mold, so the polymer isn’t as strong as it could be…”
The internals also suffer damage, throwing off his equilibrium and causing him to stumble for what is maybe the first time in his robot-life: “So this is what it’s like to lose your sense of balance…”
He gathers data during the race regarding what features his design is lacking and reworks it after returning to NRC, installing an antigravity unit, high-speed movement, flight, a laser and Rabbit Mimic mode based on rabbits that Silver introduces him to.
