Spaceman arrives to steal Earth's bug spray, more at 11.
Thanks to Lazar, DrMagnus, Zyn, SunnyClockwork, Tufto, riyangendut, Icepick/mortos, and Shio for crit.
"But Lex why couldn't it just invent bug spray on its own?" Because that's not the way it thinks. Making extradimensional exosuits comes to it more naturally than inventing bug spray.
"Sentient spacetime anomaly" is an idea I've wanted to do for a while and this was the most natural implementation for me. I might do another take on it in the future. Further inspiration was provided by a picnic and waiting too long at a train platform.
