Wonder Woman, Mera, Katana and, to the other three's surprise, Harley Quinn, were all standing atop a building in Metropolis when a portal opened. Out stepped a woman in green with antennae and big, kind eyes.
"Mantis, it's been a while." commented Wonder Woman.
"I try not to use the inter-dimensional portals unless needed, and this seemed like the time to do so." replied Mantis. She held a box, holding a colored gem.
"What is this?" asked Wonder Woman.
"An Infinity Stone, this one controls reality. A madman tried to erase many from existence, including myself, but we thwarted him. We decided it would be best if the stones were harder to find." answered Mantis. Wonder Woman took the box.
"I can feel the power radiating, it feels comparable to a Mother Box." she commented.
"Then it should be buried." added Mera. "We don't need another space dictator trying to claim this planet."
"I say I should use its power, that'd be fun." smirked Harley.
