Hackers are TOME players who have hacked their accounts to allow them to do things not intended to be possible for ordinary players, such as causing damage to the world's graphics or letting them create corrupted battle grids. Hackers usually work for, who have hired them to obtain an unspecified "ultimate power".

Hackers frequently get into fights with Alpha, Gamecrazed, Nylocke, and Flamegirl, who try to put an end to their wrongdoings.

Demonking, Neomutant, Doubling, and possibly Rockoon have left, though whether they will continue to hack independently remains to be seen.
