The Ever-Expanding Bunker Wiki

"YEAH BUDDY" - The Tester

The Tester is the leader of The I.R.O.N., lives on level 106 (nicknamed "The Olympia"), and is possibly the physically strongest person in the bunker. Born and biologically female, she somehow broke the breeding factories' testosterone tunnels and ate three year's worth of it, which may have changed her into how she is now. According to the square, guards have tried to sedate her with estrogen injections, but her body turned it into testosterone. Despite her menacing appearance, she seems to be kind and welcoming to new members of IRON, as she will "beat up anyone making fun of somebody trying to get into shape".
