Doctor Ub'x

Doctor Ub'x is a villain from the DC Universe who serves as the arch-nemesis of Ch'p, the squirrel-like Green Lantern of H'lven. A cunning adversary from the same homeworld, Ub'x uses his intellect to menace Ch'p and the Green Lantern Corps.

Steve Englehart and Joe Staton introduced Doctor Ub'x to the DC Universe in Green Lantern #201 in 1986, dropping this intriguing figure straight into the heart of the Copper Age's most cosmically ambitious corner of comics. With appearances spread across Green Lantern and The Green Lantern Corps, Ub'x keeps genuinely rarefied company — sharing pages with Hal Jordan, Ch'p, Arisia, and Salakk — placing this character squarely within one of DC's richest ensemble casts of the era. The debut issue itself carries key-issue status, making it a worthy addition to any serious collection. Compact in total appearances but punchy in pedigree, Doctor Ub'x is exactly the kind of deep-cut cosmic character that rewards the curious fan willing to dig into the Green Lantern mythos beyond the familiar names.
