Giant-Size Doctor Strange #1

Hurling thru the void of space, Strange sees a vision of Victoria Bentley, surrounded by machinery. So he's taken back when he lands on a jungle planet inhabited by savage, monstrous creatures. Then, he finds an underground cavern, and inside it, an elaborate machine, from which emits a mental challenge. Yandroth, Scientist Supreme, claims to have unlocked the \"inner-most secrets of the cosmos\", and intends to make Victoria his queen-- to rule many planets, including, eventually, Earth. Strange refuses to depart, and realizes a challenge of science vs. magic awaits him...
