2. Lana Lang
After the E-2 Lois and Clark were married, they had a series in Superman Family, in which the E-2 Lana was introduced in Superman Family 203 as a television critic for the Daily Star.
Lana Bronze Age
Marty Pasko said he had trouble writing stories for Superman’s supporting characters. Too often, he wanted to do something and was told he couldn’t because someone else had plans. No one was using Lana Lang, so in 1977, Superman 317, Morgan Edge hired Lana to co-anchor with Clark on WGBS.
3. Jimmy Olsen
Both are not all that different. In each, he goes unnamed and doesn’t look like the classic Jimmy. The first, Action Comics #6, 1938 he’s much younger and has blonde hair. All that changes with Superman #12, 1941, where he starts to look the traditional Jimmy, but he’s a reporter—not a photographer—which was done to better the Superman Radio show at the time.
Over the decades, he appeared only 62 times, and after an appearance in Action 200 in 1955, it would be nearly 30 years before he showed up again. It was during the 70s and 80s, when DC started telling new Earth-2 Tales again that he began appearing, with an older, balding, not-named—but sitting next to Lois—at the Trial of the JSA in America vs. the Justice Society #3, from 1985.
4. Christopher Kent
Both are E. ALL OF THE ABOVE
Though he’s different these days, as seen in Sinister Son, his first appearance was in Action Comics Vol 1 844 back in 2006. This trade is a fantastic place to read how he entered the DC mythos.
5. FALSE: Professor Emil Hamilton was both an ally and an adversary.
6. According to the DC Wiki, there are at least 33 surprising forms of Kryptonite.
9.
Krypto, the Super Dog, first appeared in 1955. Streaky, The Super Cat, appeared in the Super-Girl backup of Action Comics in 1960. Beppo made his debut in 1959. Comet came from a unique place, with his first appearance in a Legion of Super-Heroes tale (1962) that also marked the first appearance of the Legion of Super-Pets!
