In this fanfiction scenario, Naruto finding the Infinity Gauntlet could lead to some interesting battles. He could use it against his toughest enemies like Madara or Kaguya. But he'd also have to deal with the fact that the Infinity Gauntlet comes from a different universe with different rules. He might struggle to control all the power it holds at once.
If Naruto finds the Infinity Gauntlet, it would change the Naruto universe drastically. His friends would be both amazed and worried. Sasuke might be suspicious of the gauntlet's power.

Well, in this fanfiction, the Joker could find out about Batman having the Infinity Gauntlet. He would then try to steal it, thinking he could create the most chaotic and hilarious situations. Batman would have to fight off the Joker while also dealing with the power of the gauntlet. Maybe the gauntlet gives Batman the ability to see into the Joker's mind and understand his madness better.
In a fanfiction scenario where Naruto finds a lightsaber, he could potentially incorporate it into his fighting style. He's always been creative in combat. He might use his ninja skills like speed and agility along with the lightsaber's unique capabilities. For example, he could use his shadow clone jutsu and have his clones all wield the lightsaber in different ways to confuse his enemies.
He might meet someone who is also after the scythe. This could lead to a conflict or an alliance. If it's an enemy, Naruto will surely fight to keep the scythe. But if it's someone who can help him understand the scythe better, they could team up and go on adventures together.
Another possibility is that the robot is from a future where ninjas no longer exist. It could be sent back in time for some reason, and Naruto is the key to its mission.

The baby could turn out to have some sort of special chakra. Naruto, being curious and always wanting to help, tries to find out more about it. He might seek help from Kakashi or other experienced ninjas.
It's possible that the tomb contains the remains of a powerful shinobi from the past. Naruto could learn about their history and the secrets of their power.

This could lead to him unlocking new forms of his chakra or even new ways to use the Nine - Tails' power.
Well, he could use the armor to enhance his combat abilities. Maybe it has some special powers like increased speed or strength. He might also discover a connection between the armor and an ancient ninja clan, which could lead to new adventures and unlocking more of his potential.
