Samuroid (Arrowverse)

"You have one day. Bring me the Flash, or this city dies!"

- The Samuroid threatening Kid Flash, Joe and Cisco The Samuroid, mostly refereed to as the Samurai, is the main antagonist of The Flash Season 4 premier, "The Flash Reborn". It is an evil mechanical samurai that desires to bring out the Flash and defeat him at any cost.

The Flash Reborn
The Samurai first appears causing destruction in Central City. Kid Flash, Cisco, Joe and the rest of the CCPD confront the Samurai, who demands to have the Flash confront him. Due to Barry Allen being imprisoned in the Speed Force, Team Flash is unable to meet his demands and attempt to confront the Samurai themselves, Cisco asking how he expects to fight them using only a sword. In response to Cisco's comment, the Samurai stabs his sword into the ground and creates a gigantic shockwave that takes out Team Flash and flips several cars. The Samurai tells Team Flash and the entire city that, if they don't hand over the Flash in twenty four hours, he will destroy the entire city before rocketing off. Because of the Samurai's demands, Cisco and the rest of Team Flash attempt to bring Barry out of the Speed Force, and although this is successful, Barry had been mentally damaged from his time there.

Later, the Samurai resurfaces several hours before his deadline, and with Barry unable to fight him, Kid Flash disguises himself as the Flash and confronts him in his place. The Samurai then fights with Kid Flash and realizes that he isn't the real Flash before defeating him, stabbing his sword through his tenon. The Samurai yet again demands the real Flash before flying off yet again.

At the end of his deadline, the Samurai arrives in Central City Square and is confronted by Joe and the CCPD, who tell him that Flash isn't coming. Before the battle can start, Iris steps in and tells the Samurai that, if he takes her instead, Flash will come for her. Taking her word, Samurai grabs Iris and flies off with her. After being alerted to Iris' capture, Barry manages to snap out of his mental delusions and runs after the Samurai, faster than he ever had before. The Samurai leads Flash into a series of wind turbines and uses his sword to bring the turbines down on him, however, he dodges all of the falling turbines and uses one of them to run up and grab Iris, tearing the Samurai's wings off in the process. After getting to the ground, Barry tears the Samurai's mask off, only to find that he is actually a robot. Barry takes the rest of the Samurai's parts back to S.T.A.R. Labs, where Cisco asks who build the Samurai to destroy them, also coining the name 'Samuriod' in the process.

Afterwards, in an unknown location, The Mechanic, while putting a mask on another Samuroid, tells Clifford DeVoe that the machine has served it's purpose

Trivia

 * Cisco calls the Samuroid "Samurai Jackass". This could possibly be a reference to the titular character from Samurai Jack.
