Ok, I'm a new guy here and couldn't find the thread dealing with this before so… Put here combinations that do not appear in original scp descriptions that could have very, very bad effects, even xk-scenarios coming if that happens. Also, two SCP items that would be extremely beneficial if combined. I'll start.
SCP-173 and single SCP-531 = Thing you mustn't stop looking at and thing you shouldn't look at else bad things happen.
SCP-309 and SCP-137 = Evil effects doll and thing that makes toys alive
SCP-152 or scP-140 and scp-826 = Book of endings/History of evil civilization and Draws you into the book
SCP-661 and SCP-285 = Those guys together could rule the world (if Dr. Klef agrees, of course)
Scp-109 and SCP-458 = Could end world thirst and hunger single-handedly
Please post your suggestions here…
