Well, in the world of Middle - earth from J. R. R. Tolkien's works, mithril is extremely strong. It's a precious metal that is both light and as hard as steel. It was used to make Bilbo's mail - shirt in 'The Hobbit'. It could turn aside the blows of swords and was highly sought - after. It's a material that was not only strong but also had a certain elegance to it within the context of that fictional world.
In the Halo universe, there's a material called Forerunner alloy. This stuff is incredibly strong. It was used by the advanced Forerunner civilization to build their massive and highly durable structures. Their technology, which was far more advanced than that of the humans in the Halo series, relied on this alloy. It could withstand powerful energy blasts and physical impacts that would shatter normal materials. It was an integral part of their architecture and weaponry, showing just how strong and useful it was in that fictional setting.

In science fiction, 'Magic Anti - Material' could refer to some fictional substances or technologies that have the property of being anti - to normal matter in a rather magical or extraordinary way. For example, it might be a material that can pass through solid matter without interaction, or something that can nullify the properties of regular matter on contact.
One of the strongest powers in fiction is the reality - warping ability. For example, characters like Scarlet Witch in the Marvel Comics can manipulate reality on a large scale. She can change the very fabric of existence, creating or destroying things at will.
Vibranium is also a very strong metal in fiction. In the Marvel universe, it's found mainly in Wakanda. It has the ability to absorb and store kinetic energy, which makes it both strong and useful in various applications, like in Captain America's shield.
The Masamune from various Japanese fictional works is also extremely powerful. In some stories, it is crafted by a master swordsmith and has incredible sharpness and durability. It can be used by skilled warriors to defeat powerful foes with ease. It represents the pinnacle of sword - making in Japanese culture within those fictional tales.
In fiction, flight is a very strong superpower. It provides great mobility, allowing characters like Iron Man (when in his suit) to quickly reach any location, whether it's for combat or to save someone in need. Invisibility is also quite powerful. The Invisible Woman from Fantastic Four can turn herself (and sometimes others) invisible, which is great for stealth operations. Additionally, energy projection is a common yet strong superpower. Characters like Cyclops can emit powerful energy beams from their eyes, which can be used to attack enemies or break through obstacles.
One of the often - considered strongest verses in fiction is the Dragon Ball verse. It has characters with incredibly high power levels capable of destroying planets and even universes at their peak. For example, Goku can reach Ultra Instinct, a state where his power and reflexes are off the charts.
The Dragonborn's armor in Skyrim can also be considered very strong. There are different types like Daedric Armor which has high physical and magical resistances. The armor is often enhanced with enchantments, making it formidable in battles against all kinds of foes, from dragons to powerful mages.
One of the strongest weapons in fiction is the One Ring from 'The Lord of the Rings'. It has the power to control the other Rings of Power and corrupt those who possess it. Another is the Infinity Gauntlet in the Marvel Universe. With all six Infinity Stones, it can grant the wearer god - like powers over reality, time, space, etc. And then there's the Death Star from 'Star Wars'. It has the ability to destroy entire planets with a single shot.
In my opinion, the Saiyans from 'Dragon Ball' are one of the strongest. They have the ability to transform into powerful forms like Super Saiyan, which multiplies their strength many times over. Their natural fighting instincts and high power levels make them a formidable race in the fictional universe.
