3. Chaos at the Earth's Core

Complete story — includes the ending

Supergirl, Stargirl, S.T.R.I.P.E., and Green Lantern help Warlord liberate Skartaris, a hidden world inside the Earth's core, from the dictator Deimos while protecting a large piece of kryptonite from Metallo and Silver Banshee. While Silver Banshee gets away following Deimos' defeat, Green Lantern questions why Metallo needed so much kryptonite, but Metallo is short-circuited by the Secret Society before he can divulge any details to the League. After closing up the entrance to Skartaris, Green Lantern plans to have Martian Manhunter probe Metallo's mind.
