Keith Kenyon is a criminal scientist. He drinks a gold-based serum he has been working on. This grants him superhuman strength and invulnerability. He also exhibits a golden glow.
Gold being yellow gives him a great advantage over the superhero Green Lantern, as his powers do not work on that color. However, he is defeated while trying to steal sunken gold needed for his own purpose.
Goldface creates gold-plated armor and a 'gold-gun' which sprays liquid gold. After many clashes with Green Lantern, Kenyon decides to change his motif and ruthlessly began taking over criminal empires.
He eventually moves to Central City and becomes a foe of the Flash (Barry Allen) . After serving time, he moves to Keystone City and following in his father's footsteps, became an honest Commissioner of Union 242. Over time his elixir has slowly turned his skin into an organic gold flesh. Goldface discovered that his ex-wife, Blacksmith and her Rogues were planning to take over Keystone and Central City. He worked with the Flash (Wally West) to stop the villain, even going so far as to convince the union to back up the Flash in defending the twin cities from Blacksmith's Network.

It is later revealed that Goldface's attempts at rehabilitating himself failed, leading him to incarceration in Iron Heights once more. While imprisoned there, Goldface is attacked and killed by the Darkstar Tomar Tu, seeking vengeance for his father Tomar Re, whom Goldface had killed many years prior during his enmity with Green Lantern. Hal Jordan arrives too late to stop the attack, and Barry Allen expresses regret for the potential Goldface had to make something out of his life.
Powers and Abilities
Goldface's bodily tissues are made entirely of gold. This gives him superhuman strength, endurance and invulnerability as well as to such effects, the ability to resist a Green Power Ring's energies.
The regent Keith first took in order to become Goldface also had the effect of saturating his body with Auric Radiological Energy which had the effect of changing anything he wielded it against into gold.
Weapons & Equipment
Keith Kenyon fashioned some armor out of the gold he'd used to fabricate attire befitting his villainous endeavors. He also wielded a weapon he once called his Gold Gun to hide the fact he had transmutation abilities thanks to his Auric Elixir.
In other media
Goldface made an appearance in Justice League Unlimited in episodes "Dead Reckoning", "The Great Brain Robbery" and "Alive!", where he was a member of Gorilla Grodd's (and than Lex Luthor's) Secret Society. He was voiced by Lex Lang.
