If you haven't already, please read the general overview about the Infocomics first.
Lane Mastodon first appeared in a pack-in comic strip of Leather Goddesses of Phobos, making him “the only Infocom comic book character at the point where the Infocomics project got underway” (Steve Meretzky). There, he saved the 1980s Earth from the evil Leather Goddesses within a span of few panels. This time around, he's acting in the year 2029. His origin story set 10 years before that, it's clearly not the same Lane Mastodon anymore, though given the overall tone of the story, nobody will care. At least he's given a bit more time and space to develop this time around.
