Nero placed blame on the [[Federation]] for the loss of his [[homeworld]] and sought revenge. He emerged from the black hole in 2233. The USS ''Kelvin'' was the first ship that Nero encountered and attacked; Captain [[Richard Robau]] promoted his [[first officer]], [[Lieutenant Commander]] George Kirk, to captaincy before ordering the evacuation of the ship and agreeing to come aboard the ''Narada''. There, Captain Robau was interrogated regarding the whereabouts of Spock, with whom Robau was unfamiliar and, moments after he informed Nero of the current [[stardate]], he was [[murder]]ed.

Nero then proceeded to attack the ''Kelvin''. Kirk used the ''Kelvin''{{'}}s weapons to prevent Nero from destroying the evacuating shuttles departing the ship, ultimately sacrificing himself by [[kamikaze|ramming]] the ''Kelvin'' into the ''Narada''. Kirk's actions saved some eight hundred lives, including his wife, {{alt|Winona Kirk|Winona}}, and their newborn son, {{alt|James T. Kirk|James}}, but failed to destroy the ''Narada''.

As a major consequence of these events, James Kirk grew up without his father and without the ambitions his father gave him in the prime reality. However, he was persuaded by {{alt|Christopher Pike}} to join [[Starfleet]], three years later [[2252|than he had done]] in the prime reality.

In the meantime, other events occurred differently. {{alt|Pavel Chekov}} was born in [[2241]], while the Romulans were confirmed as relatives of the Vulcans. Plans for the {{class|Constitution|alternate reality}} were pushed back by a decade and the USS ''Enterprise'' began construction in [[2255]] at the [[Riverside Shipyard]] in [[Iowa]], with a number of internal, external, and systems design differences to the prime reality version. It was launched three years later, already as the Federation [[flagship]] under the command of Captain Pike. {{alt|Spock}} was already promoted to [[commander]] by this point. Starfleet continued using the simple <Earth calendar year>.<day of the year> format for stardates, and had already begun using gold, blue, and red colors for {{alt|Starfleet uniform|their uniforms}}. They also adopted the ''Kelvin'' [[assignment patch]] as the sole [[Starfleet insignia]]. The [[Vulcan High Command]] was reinstated as the [[Vulcan High Council]].

{{bginfo|According to the [[Blu-ray Disc|Blu-ray]] featurette ''{{dis|Star Trek|Three disc Blu-ray|Starships}}'', the {{type|Kelvin}} ships were 1,500 feet long, while the ''Enterprise'' was approximately 2,380 feet long. This implies that, in the prime reality, Starfleet tried to streamline the size of their ships while, in the alternate one, they did not.}}

Along with the ''Enterprise'', various technological, scientific, and aesthetic aspects of a multitude of cultures, including those of Earth, varied greatly in difference and advancement in comparison with that of the prime reality.
