>>55287400According to the legend, whoever pulled the 7 needles would have the dragon's power to reshape the Earth.
Pokey's plan was destroy the world. Why? Because he was bored. He reached godhood, and only wasted it in reaching the ultimate point of decadence.
Anyway, Lucas and his team goes in, pulls needles, the world changes. Pokey's "Masked Man" also pulls the needles, but because he has no mind or reason, the world probably would've stayed the same? He doesn't have a heart anymore, and it would've been interesting to see if he still had it (if beta bosses are to go by, Lucas' brother was still concious, but he no longer had control of his soul).
Anyway, at the end the game gives you a choice (but it doesn't matter because Lucas does it anyway), and the last needle us pulled out. The dragon is awakened, and looks like it's the end. But a miracle happened: everybody is alive, and safe, and in a new land.
Lucas created a new world, and Mother 3 comes to a happy end. Lucas saved everyone, and a new world is open to everyone. Hell, I bet even the dragon is happy he got to be free rather than sealed.
I always felt when everybody goes "thank you [PLAYER]", the last guy to thank you is Lucas. Was a sad tale? Yes, but like we knew: No crying until the end.
