New Life in Zelmo (Epsilon)

New Life in Zelmo is an American science fiction comic book series created by TBD, being published by Epsilon Publishing from October 1963 until August 1970.

Synopsis
Two siblings named David and Kimberly Green were outside one night until they discover a mysterious UFO, as they decide to sneak in and look around thinking it's some sort of artifact. However, the UFO turns out to be real as it launches the two far into an exoplanet called Zelmo, meeting different aliens and finding themselves at risk in several situations while trying to find a way back to Earth.

Main

 * David Green - a cocky and somewhat immature teenage boy who decided that he and Kimberly should sneak into the UFO and caused themselves to land in Zelmo in the first place. At first, he enjoyed the place to the point of wanting to stay to start a new life, but after dealing with several threats that have nearly killed them, he slowly starts to become more mature as the series went on and sets to find a way back home.
 * Kimberly Green - an intelligent and serious, yet sometimes sarcastic teenage girl who finds David's antics to be annoying because of how dumb his decisions tend to be, and has tried to warn David to not mess with the UFO. Since both of them landed in Zelmo, Kimberly has been focused on finding a way to return to Earth no matter what it takes and has been getting her brother to do the same.

Supporting

 * Xandroy - a bizarre and curious, yet nervous alien who was an outcast to the other aliens in Zelmo as he discovers the UFO that crashed into Zelmo and meets David and Kimberly, being the first alien to befriend the two.
