Today's Fact
Checked against independent sources — the issues are cited below.
The little fork rising from Blackagar Boltagon's brow is not royal jewelry. Marvel's official history describes it as a working antenna that helps him govern the electron-harnessing power wired into the speech center of his brain, letting him pour that energy inward for strength and speed, fire it as concussive force, or fold electrons into anti-electrons and fly. When the fork works, the most dangerous voice on Earth stays precisely metered.
In Fantastic Four: Atlantis Rising #2 (1995) a battle against Thor damaged that antenna, and patching it proved harder than forging it — one repair attempt through Henry Pym had already failed before events peaked in Fantastic Four Vol. 1 #411 (1996). There the king, his mind fracturing, fled across the Colorado wilderness seeing his own family as alien attackers, and still knocked out Medusa, Ahura and Karnak with a single blast while trying to escape them.
The true terror was arithmetic: a ruler losing his reason might one day forget the discipline that keeps his vocal cords still, and a slip measured in whispers can level fortifications. He was subdued before that slip came, and Mr. Fantastic working with Psi-Lord, the adult Franklin Richards, finally repaired the fork and restored him. Attilan's crown, it turns out, has a load-bearing ornament.
Why It's Obscure
Every king has a weakness a portrait can show: his sits in the middle of his forehead, tuned like an instrument.
