Today's Fact
Checked against independent sources — the issues are cited below.
For his first decade Moon Knight was simply a superbly trained man — until Moon Knight: Fist of Khonshu #1 (1985) retooled him. Ancient priests of Khonshu called Marc Spector out of retirement, handed him a new costume and Egyptian-themed weapons of gold and ivory, and with the regalia came a gift his earlier series never had: strength that waxed and waned with the phases of the moon.
The scale was printed in black and white. The Deluxe Edition of the Official Handbook of the Marvel Universe rated the empowered Moon Knight at up to two tons under a full moon, while even at a new moon he could still lift several hundred pounds. Fist of Khonshu #2 played the adjustment for a gag — teased that superheroes bend steel bars, Spector had to remind himself that, as of last issue, he actually could.
Later writers quietly took the gift back. When the acclaimed 2006 Moon Knight series relaunched him, the lunar strength was gone and he was once again only peak human — which is how most modern readers know him. The moon-powered years survive as a six-issue experiment that briefly turned Marvel's most street-level vigilante into a hero whose power level you could check against a calendar.
Why It's Obscure
Most heroes check a wound or a weapon before a fight. For six issues in 1985, Marc Spector checked the sky.
