History
Shadow Goblins were inhabitants of the Twelfth Dimension, which were all invisible to the human eye.
Many Shadow Goblins attempted to invade the Earth dimension after a rift between it and their dimension opened just outside of Teetering Rocks, Idaho. The time-displaced young Beast passed out when he used the Third Eye of Horus to see the Shadow Goblins, forcing Doctor Strange to spend several hours defending both of them against the creatures.[1]Notes
- Despite Doctor Strange noting their presence in All-New X-Men (Vol. 2) #8, none of the creatures seen in the issue are identified as Shadow Goblins.
