Non-Disney Vs DC Villains War
Killer Croc joins the Penguin's team of super-villains, in hopes to make a stand against other forces, who would threaten them, appearing as it's main enforcer. His first challenge emerges, as the Heylin, a group of lethal warriors, directed by Wuya, attack the team. Although failing at Jack Spicer's secret weapon, Killer Croc's efficiency in battle turns the odds for the team, after his two fellow associates, Firefly and Ragdoll, fail to deal with their enemies. He beats down the Chameleon-Bot with a stack of barrels, and knocks out Tubbimura, with his brute strenght. Due to Killer Croc's efficiency in battle, the team scores their first victory.
