From this point forward, Knodar became increasing obsessed with defeating Green Lantern.  Within months (20^thcentury time) of his initial encounter, he had once again appeared in Gotham, this time switching places with Green Lantern and capturing a hapless Doiby Dickles.  When Dickles answers his question that train robber Jesse James was history’s most brazen criminal, Knodar resolves to be a greater train bandit.  Meanwhile, Green Lantern finds himself with Rhya, an educator charged with reforming Knodar.  After convincing her that he is the real Green Lantern and not Knodar in disguise, they realize the criminal must once again be plaguing the 20^th century and travel back to 1948 via power ring.  They arrive in time to catch Knodar robbing a large passenger train but are subdued when Knodar’s uses a metal controller to swat Green Lantern with a large pipe.

Changing tactics, Green Lantern switches to his civilian identity and he and Rhya join the next train as passengers.  Predictably, Knodar attempts to rob it and when they rise to thwart him, they are captured and left in a death trap in which a passing train trips a wire that electrocutes them.    As Knodar heads to the railroad office intending to up Jesse James train heists by stealing an entire railroad, Green Lantern managed to free himself and takes up the chase.  Cornered in a railway office where their weapons neutralize each other, Green Lantern subdues Knodar with simple fisticuffs.  With criminal unconscious, he transports Rhya and her quarry back to the 25^th century (Green Lantern #30).

Within months Knodar was again back in the 20^th century, this time somewhat by accident.  Stealing a centuries-old time machine, he set course for the 23^rd century where he intended to hook up with a notorious female criminal, the Black-Eyed Bandit.   He overshoots his marks, arrive in the summer of 1948 and in the middle of Gotham’s “Golden Jubilee” celebration.    Mistaking starlet Ann Hunt for the Black-Eyed Bandit, he drags her along on a crime spree stealing the prizes set aside for the jubilee.  At his first  target,  a giant golden key, he  is intercepted by Green Lantern.  Shocked at the heroes appearance in what he believe the 23^rd century, he is delighted when Ann Hunt inadvertently subdues the hero with the key.

For his next heist, Knodar and his “accomplice” target the Grand Jubilee Ball, a costume party of Gotham’s elite.  Claiming the key theft was a prank, he is invited as a guest of the mayor and unaware that Green Lantern and Doiby are in attendance in disguise, begins to rob the attendees.  When Green Lantern reveals himself, a brief scuffle ensues before Knodar escapes to his accomplice in the car below.  They drive to a museum where Green Lantern and Doiby are ambushed and subdued.  While Knodar gloats over a death trap he has created for them, Ann Hunt slips out and steal his metal control wand and subdues the futuristic crimimal.   She then frees Green Lantern, who sends Knodar back to the 25^th century.  Knodar is returned to his cell, convinced that he has been in the 23^rd century the whole time (All-American Comics #100).

Further encounters with Green Lantern have not been recorded.  Knodar’s next documented appearance was decades later during the Crisis on Infinite Earths.  Taking advantage of the carnage, Knodar travels back to the 20^th century and while only a year has passed in his time, nearly 40 have lapsed in the 20^th century.  Arriving in Los Angeles, he assembles a gang of time-displaced gangsters from the 1930’s to begin a series of robberies only to run afoul of the Star-Spangled Kid and heroine Jonni Thunder.   Corraling Knodar on a movie set, they defeat him by dropping a wooded prop on him that looks like a metal airplane, which Knodar’s metal controller won’t deflect (Infinity Inc. #23-24). 

Whether Knodar had other run-ins on Earth-Two is unrecorded and his ultimate fate is unknown.
