In OP there are some references to hindu mythology. Luffy's character is something of a reference to hanuman. His ultimate attack, bajrang gun, is named after hanuman, and his father has wind powers, much like Hanuman's father Vayu(albeit this could be taken from journey to the west, because Wukong was also based off hanuman).
Anyways, Usopp is one of the best snipers in one piece and by the EoS, he will surely be the greatest. In hinduism, one of the greatest snipers was Arjuna, who was a master of archery. Arjuna, who himself was a demigod, attained supernatural abilities due to his worship of the gods. Due to his devotion, the gods gave him divine weapons, known as the Astras. Some of these weapons were so powerful that they had the ability to destroy the world; Shiva, for example, gave him a weapon so strong that it could kill any god, but was so powerful that it would destroy the world if used on lesser beings.
idk if Oda has any idea of what mahabharata is, but Usopp is a "god" and he is one of the greatest snipers, and there are weapons in OP that have the ability to end the world that are named after gods(much like the hindu pashupatastra, brahmastra, ect.). So I think that between Pluton and Uranus, Usopp will use one of these weapons in the final war.
