Most of the Avengers have been missing for months, the Scarlet Witch, Clint Barton, and Sam Wilson have been in hiding since. After Kang the Conqueror took complete control of the Multiverse, a young boy in a Neuro-Kinetic armor named Nathaniel Richards came to the present to warn the Avengers of the coming threat, his future self after seeing glimpses of his future. Only, when he came to the present, after the defeat of Thanos and the death of Tony Stark, The Avengers had already been disbanded and Nathaniel could no longer travel again due to a flaw in his suit, which had a time machine built into it, so as he searches for a way to stop the future threat, he meets the legendary Nick Fury, who informs him about of a group of exceptional people who have the skill and powers of the Avengers, such as Kate Bishop, America Chavez, Peter Parker, Billy Maximoff and more. Using S.H.I.E.L.D. Technology, the founder of the avengers and the boy from the future gradually finds a few young people with exceptional abilities or skills, and together with them, he starts a team named the Young Avengers. Nathaniel, as Iron Lad, becomes their leader. The team thrives at first and gradually expands its ranks. Until their worst possible enemy, Kang the Conqueror himself arrives in their time, bringing a possible threat or ally with him.
