Legion of Super-Heroes is confusing as balls. The Legion of Super-Heroes have some very good stories, but they can also be impossible to figure out how to get into. The massive continuity issues between the three different main versions of the team, and the endless characters with seemingly silly names can make it very inaccessible. They're actually an incredibly rich and diverse wealth of stories that are well worth your time getting into if you can find the good parts, but the trick is figuring out where to get started.
- Legion of Super-Heroes: An Eye for an Eye is the beginning arc of Volume 3, by Paul Levitz and Keith Giffen. Featuring the Original Legion, the story features a massive battle against the Legion of Super-Villains and ends in the tragic death of a long-time Legionnaire.
- Legion of Super-Heroes: Teenage Revolution is the first arc of Volume 5, debuting the Prime Legion reboot by Mark Waid and Barry Kitson. It's really freaking good.
- Legion of Super-Heroes: The Beginning of Tomorrow is the first and origin story of the Reboot Legion, published immediately after Zero Hour by Mark Waid, Tom McCraw, Stuart Immonen and Jeffrey Moy. Using a vastly different tone than the preceding Five Years Later stories by portraying a lighter and more idealistic Legion, it does an excellent job of establishing the characters and building their new universe.
- Lightning Saga is a JLA/JSA crossover written by Brad Meltzer and Geoff Johns, featuring the Original Legion's return following Infinite Crisis.
- Superman and the Legion of Super-Heroes by Geoff Johns and Gary Frank is the follow-up arc to Lightning Saga, exploring the original Legion's return to continuity and the details of their time spent lost without Superman. Taking place on a future Earth grown violent with xenophobia, Superman returns to the future and helps the Legion fight against oppression and racial hatred.
