Basil Elks is a petty thief who breaks into a museum to steal what he believes is an ordinary emerald - but is in fact an alien Kree artifact called the Alpha Stone. Elks, however, miscalculates the security guards rounds and is caught and fired upon when he reaches for a weapon. The guard’s bullet accidentally hits and shatters the gem, causing an explosion that transforms Elks into a humanoid reptilian - his skin becomes green and scaly and his eyes are now large and red. Elks then flash-freezes the guard in place, and realizing that he now has superhuman abilities, decides to become a supervillain and calls himself the Basilisk. He faced off against Spider-Man, Mister Fantastic, Captain Marvel and the Mole Man which ended with him being imprisoned in another Kree artifact called the Omega Stone which ended up in lava.
