This second omnibus hardcover collecting the Legion of Super-Heroes from the mid-1960s features the tales that established this futuristic super-team as one of the most enduring and appealing in comics. These stories begin as the Legion runs into trouble when it rejects a new applicant- Bizarro-Superboy, the comically imperfect duplicate of the Teen of Steel. The team also faces the menaces of Lightning Lord, the Time Trapper, Computo and more! Also, two of the Legion's founders, Lightning Lad and Saturn Girl, get married, and the team must escape the Super Stalag of Space. Collects ADVENTURE COMICS #329-360 and SUPERBOY #124-125.
