Legion of Doom

Eobard Thawne sought out Damien Darhk and later Malcolm Merlyn to form a syndicate with the purpose of locating the Spear of Destiny, hoping to rewrite reality itself.

History
Eobard Thawne first sought out Damien Darhk in 1942. The two created an aberration where New York City was nuked. However, the Legends thwarted their plans and Eobard Thawne decided to move on.

Eobard then made his way to Nazi, Germany in search for the Askaran Amulet. Though the Legends and the Justice Society of America reached it before he could, Eobard broke into the JSA headquarters and stole it after killing Rex Tyler.

In 1987, Eobard made contact with Damen Darhk once more. The two planned to obtain an artifact from the Soviet Union's KGB and blow up the White House. Once again, the two were thwarted by the Legends. After their second failure as a team, Eobard Thawne suggested they change their destinies, presenting Damien Darhk with a time sphere.

Some time later, they time traveled to Chicago in 1927. Now having Malcolm Merlyn recruited, the trio offered their services to Al Capone. The three had Al Capone dispose of Eliot Ness, though it was bait to lure the Legends. Eobard Thawne later kidnapped Sara Lance and Martin Stein. Eobard Thawne then used a device to steal Martin Stein's appearance to infiltrate the Legends. As Martin, he searched for the missing artifact but was interrupted by Sara Lance, forcing him to come to a halt. After realizing Nate Heywood was aware he isn't Martin, Eobard ran off but was struck by a speedster weapon, temporarily subduing him. Eobard Thawne quickly regained strength and attacked Jefferson Jackson, though Ray Palmer surprised him with an attack of his own. Eobard made his way to the bridge of the Waverider and locked himself in. Eobard then turned the cloaking off and opened the cargo bay doors open, allowing Malcolm and Al Capone's men come on board. Eobard stopped Mick, believing he was trying to get away with the artifact, though was once again struck by a speedster weapon. Eobard noted he knew Amaya was only on the team to avenge him for killing Rex Tyler. With Amaya briefly distraught, Eobard sped off. Meanwhile, Sara Lance fought Malcolm and eventually got the upper hand. Before Sara could kill Malcolm, the latter offered Stein's location in return for the artifact. Later, Eobard revealed the two artifacts formed a compass leading to the Spear of Destiny.

Behind the scenes

 * In DC Comics, Eobard Thawne has indeed created a syndicate under the alias "Mister Zyx/Professor Adrian Zoom", albeit its purposes were much less mysterious: Zoom tried to spread heroin through Central City and, eventually, the whole of Earth, creating an army of heroin addicts for him to control.
 * Additionally, the Crime Syndicate was the name for multiple organizations created by the alternate versions of core Justice League members. These villainous doppelgängers of heroes would spread crime and control over their universes (most notable, Earth Three) and eventually tried to conquer Justice League's universe.
 * Notably, Eobard Thawne was not a member in any variation of the Legion of Doom, but rather one of the multiverse traveling adventurers of the Secret Society of Super-Villains as Professor Zoom. This group (now under the leadership of Libra, prophet of Darkseid) was later joined by the second Zoom, Hunter Zolomon.
