Armor Games

Please help me. The second character, grayed out and with a pitchfork of sorts, says I must beat the game to use him.

SPOILERS
I already finished it and the word is "Axis".
END of SPOILERS

But I do not know what to do with this word now. I tried typing it and selecting the first character. It didn't work. I tried typing it and then pressing <enter>. It didn't work either. So, what is the word for, if it is for anything at all?

Any help will be very much appreciated.
