These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Talec is an extraterrestrial drug dealer who has come to Earth to harvest human endorphins from people's brains, which are an extremely valuable and illegal commodity on his planet. He overdoses his victims with heroin before implanting a retractable spike in their skull to extract the fluid, killing them in the process. He kills many people during his rampage, and has no compunction with murdering any bystanders who get in his way by using either his energy weapon or homing disk projectiles on them. When Azeck, a cop from Talecís planet, tracks him down, he fatally wounds him as well. Talec intends to kill thousands of people on Earth to get the drug cheaply, before going back to his home world and return with more of his gang to slaughter humans in even greater numbers.
