(PS1) Digimon World [Part 6]
Numemon passes (again), and after much training I obtain my very own Monochromon, who with its sheer strength and indomitable will (and much of my resources and money), not only liberates the factory, but defeat Ninjamon, Pixiemon and Airdramon.
At last, the way to the final dungeon has opened, and it's onto me to farm for the money and buy the necessary resources for the final battle.
