Legion of Doom's alternate reality

"My name is Eobard Thawne. With the help of Damien Darhk, Malcolm Merlyn, Leonard Snart, and Mick Rory, I've obtained the Spear of Destiny, an ancient artifact with the power to rewrite reality itself, and we have. It's a brave new world."

- Eobard Thawne

The Legion of Doom's alternate reality is a timeline created by the Legion of Doom when they obtained the Spear of Destiny and used it to rewrite history. This timeline was specially designed to match the wants of all the members of the Legion, as well as to punish the Legends.

Changes to the reality after alteration

 * The Legends do not have their powers/tech nor any knowledge of the unaltered reality. They are each lowly servants of the Legion or leading irrelevant lives, with the exception of Mick Rory.
 * Eobard Thawne is the CEO of a new S.T.A.R. Labs and Mayor of Central City, and has used his considerable intellect and newfound resources to solve the world's energy and environmental crises for sake of fame. As an award-winning and renowned scientist and businessman, he has become incredibly famous and influential, to the point that he's personally friends with the President of the United States. According to Nate Heywood, Thawne is widely considered to be the smartest man in the world.
 * Hunter Zolomon is imprisoned in a special containment cell in Thawne's lab.
 * The Waverider is miniaturized and kept on Thawne's desk, operating solely on reserve power, with the engines and time drive offline. Rip Hunter is trapped inside with no one but Gideon for company, and has spent the past year descending into despair and alcoholism, perfecting his baking skills.
 * Martin Stein is a scientist working for S.T.A.R. Labs. Jefferson Jackson also works for S.T.A.R. Labs, serving directly under Thawne as Stein's superior. Under Thawne's orders, Jackson is extremely harsh and demanding toward Stein.
 * Ray Palmer works as a custodian for S.T.A.R. Labs, and doesn't appear to have any formal education or credentials, though he still possesses an instinctive knowledge of engineering.
 * Damien Darhk is now the mayor of Star City He is once again in possession of the Khushu Idol and all of the magical powers that it grants him.
 * Sara Lance and Amaya Jiwe work as the personal assassins for Damien Darhk, hunting down and killing vigilantes.
 * Ragman, Artemis, Wild Dog, The Flash, Green Arrow, Vigilante, and Spartan's masks are put on display in Damien's mayoral office, thus implying their apparent deaths at the hands of Darhk or his underlings.
 * Felicity Smoak was the last vigilante left in Star City, and her mask was taken to be put on display after she was captured and killed by Sara and Amaya.
 * Malcolm Merlyn is once again the rich, famous, and well-respected CEO of Merlyn Global Group as well as the leader of the League of Assassins, and he has his left hand back.
 * His wife and son are still alive in this reality, and his daughter Thea adores him.
 * Nyssa al Ghul is living a "miserable closeted life" in Ohio.
 * Leonard Snart and Mick Rory are wealthy enough to "own half of Central City", in Snart's own words, although they still occasionally commit crimes just for fun. At the same time, their "criminal status" is dubious as they have enough influence that a group of CCPD officers didn't even bother arresting them after they were caught robbing a bank in broad daylight, simply letting them walk free instead.
 * Nate Heywood is a conspiracy theorist who lives in his mother's basement and spends his free time blogging about his theories.
 * The President of the United States is not Susan Brayden,
 * Thawne refers to him as "Mr. President" indicating the President is male
 * Thawne mentions having diner at his hotel and he also refers to the First Lady as "Mel." All are possible references to the the current President of the United States in real life, Donald Trump, and his wife, First Lady Melania Trump.

Things left intact after alteration

 * Everyone in the Legion of Doom retained their memories of the original reality, since they were the ones who altered it. Eobard Thawne kept his superhuman powers, and Leonard Snart and Mick Rory kept their signature weapons.
 * Rip Hunter and Gideon also retained their memories, for reasons unknown. Additionally, while the rest of the Legends (along with everyone else on Earth) had their memories altered to fit the new reality, they still retained some subconscious memories of the original reality. This led Nate to figure out that reality had been altered, and inspired Ray to create a device that would restore people's memories of the original reality, which he then used to restore the memories of the rest of the team (except for Martin).
 * The fact that Hunter Zolomon still exists and still apparently wants to kill Thawne suggests that the Spear of Destiny - despite being able to alter reality itself - cannot affect the Speed Force or its enforcers. (Alternatively, Thawne could've simply chosen to keep Zolomon around in the new reality for the sake of tormenting him, just as he kept the Legends alive in order to punish them.)

Behind the scenes

 * The new design of S.T.A.R. Labs is a reference to the Hall of Doom, which in the comics is the headquarters for the Legion of Doom.
