With nothing stopping her, Laura was probably the one with the most kills in the least amount of time, however, the kills counted included both Ribix and Ribots.
The only ones that she didn't attack were perhaps her own army that entered the battle with her.
She brought out her secret powerful weapon and an army filled with soldiers that wielded this same weapon that was specially made to defeat Ribix.
With just a single attack, the weapon was able to directly take the life of the Ribix without fail.
This was her secret backup plan that she had hidden and was meant to be used after the war was over. The purpose of this special army was to kill off all the survivors that had fought the war, but unfortunately, Laura's plans were crushed when Captain Liv somehow saw through her plan and forced her to bring out her secret card.
