Magnus, Robot Fighter #33

In "The Aliens," Captain Johner and his crew face off against the alien warship commanded by Zarz, a saucer-headed giant whose people are equally determined to protect their world. With both ships damaged and Earth’s location at risk, Johner makes a bold move: using a tele-translator, he proposes a daring exchange—half the Earth crew to the alien planet, half the aliens to Earth—to forge a new beginning.
