Scarlet Spider #20
In "Sibling Rivalry Part 2," Kaine and Otto face off against the Jackal’s twisted experiments as their shared past resurfaces in the form of dangerous mutant spiders and a race to destroy genetic samples. With tension rising between the two spider-heroes, their fight for survival takes a dark turn when Otto’s desperate act may not have erased all traces of his DNA. Written by Christopher Yost and Erik Burnham, with art by Pat Olliffe, InHyuk Lee, and Paco Medina, and cover by Ryan Stegman, this 2013 issue delivers a gripping, character-driven clash with high stakes and emotional weight.
