A large room hidden under the House of Evolution headquarters, secured by a metal trapdoor.
Overview[]
This combat experimentation room is the largest in the facility and serves as the battleground for the fights between Genos and Carnage Kabuto, as well as Saitama and Carnage Kabuto.
When Carnage Kabuto enters Carnage Mode, the room initiates a lockdown; powerful containment doors seal the entrance, the lights go off, plunging the area into darkness, and red emergency lights activate along with an alarm. Following Kabuto's defeat, the room returned to its usual white appearance, though a significant hole remains in one wall, created when Saitama punched through it in a hurry to reach a supermarket sale.
