There's no need to worry! Mr. Sinister, the sadistic puppeteer of the Hellions, is just fine! Right? Eh, not really. Sinister's menacing clone is on his way to Krakoa to reclaim the cape... and destroy the Hellions in the process! Elsewhere, Tarn the Uncaring and his murderous Locus Vile are also out for vengeance on both Sinister and the Hellions! This could get ugly. But never fear, the mutants you love to hate are ready for the ultimate rematch! Well... sort of. Almost ready. But little do they know that Psylocke's secret side deal with Sinister is about to cause a schism that just might end the team before the villains can! Collecting: Hellions (2020) 13-18
