THE UNCANNY UNICORN

ABOUT THE UNICORN: (Excerpt used by permission from the Iron Man Armory database)

A horny psycho who blasted on the scene in TALES OF SUSPENSE #56, The Uncanny Unicorn's power is almost beyond description. Possessing an unbeatable offense with a fool-proof defense this Czech born Soviet Intelligence Agent (real name: Milos Masaryk) is literally a blast from Iron Man's Cold War Past.
Wearing a kind of upper body rig, with switches and buttons, that extends upwards to a helmet, his ingenious debut costume was built by the original Crimson Dynamo (Prof. Anton Vanko), before his defection, and was more powerful than Iron Man's armor. While the costume contains many weapons controlled with the knobs on his chest, it is the Unicorn's mighty Power Horn, built into his helmet, that is the source of his awesome might.
The horn makes Unicorn as effective as an entire battery of anti-tank guns. Capable of raising objects magnetically, regardless of their weight, firing a heat beam, smashing concrete and deflecting and destroying missiles, the horn packs quite a wallop. Possibly his greatest power is the horn's ability to throw a radiating energy shield around him strong enough to protect against the explosive force of a thousand tons of TNT. His Force Bolt can melt steel, and eventually, even Iron Man's armor if given the time. And his jet assisted flight makes him quite mobile.
Reborn in IRON MAN #4, the Unicorn returned with even more devastating power and new sleeker costume. Brainwashed by his Communist handlers to be a loyal and perfect guinea pig, he was subjected to repeated doses of the Hyper Activator--A device which induces a permanent condition of strength and power in the body usually only attained in rare crisis moments. This so-called, "Hyper Power," allows the Unicorn to smash steel girders with his bare hands. All of his senses, especially his hearing, have been heightened by the process as well. Unfortunately the long range effect of hyper power is a shorter lifespan and a quick descent into madness.
After donning an improved costume, Unicorn turned on his captors and became a free-lance criminal. Containing deadly innovations, the specially woven, form-fitting green and orange steel-mesh costume no longer has the bulk and clumsiness of the previous model. The Unicorn's horn was also made more versatile, more deadly than ever, powered by a mighty power pack on his belt. The new suit also included rockets in the boots.
The Unicorn seemingly fell to his death at the end of IM #4, but he soon returned, revealing that his emergency boosters had taken him to safety. After being tricked by the Red Ghost to steal a Stark invention, Unicorn was betrayed and actually teamed with Iron Man to defeat the mist-like mad scientist, before betraying Shellhead himself of course.
Although he battled IM several times, The Unicorn is now believed to be dead, having walked into the ocean under Titanium Man's spell. A villain calling himself The Unicorn did show up as part of The Stockpile, a mercenary team hired by Morgan Stark at the end of IRON MAN VOLUME I (issue #320). Same guy? Only time will tell.
