World's Finest Comics #262

In "The Power of the Pi-Meson Man!", a man transformed by a radiation experiment gains the ability to create an invisible body—leaving even Batman and Superman powerless to stop him. Only Betsy Pyatt, a young blind girl, can perceive his true form, making her the key to uncovering his hidden threat.

In "The Ghost of Adam Strange," a spectral figure of the hero appears on Rann, haunting the ruins where he once stood. With the help of Trixie Magruder, a young woman from the Forever People, he uncovers the truth: Adam Strange’s mind became trapped between worlds during a visit to Rann’s ancient ruins, ensnared by a powerful psi-being that fed on his inner conflict. Now, using the Justice League’s teleporter, they must find a way to reach him before he’s lost forever.
