Scatterbrain (Will Deguchi) was created by writer Peter B. Gillis and artist Brent Anderson and debuted in Strikeforce: Morituri #6 (May 1987).

Apparently, at a young age, possibly as a child, he experienced a devastating earthquake in Missouri, an experience he used years later to telepathically project it in battle.

[1] In 2073, the young Deguchi decided to volunteer for the Morituri program, hoping to assist in the ongoing war of Earth against the alien invaders known as the Horde.

The aforementioned program granted superhuman powers to ordinary humans, in turn transforming them into super-powered soldiers against the Horde.

[2] After going through the process, Deguchi, like most Morituri, was instructed to participate in a test in the booby-trapped Biowar Facility Alpha (nicknamed "the Garden"), so that his powers would burst forth under extreme pressure and stress.

Feeling guilty for him, the inventor of the Morituri process and the Garden facility, Dr. Kimmo Tuolema, designed a leg brace for Deguchi, which became a permanent part of his.

[3] Later, thanks to the data that fellow member Adept had accumulated from a mission of the team in the Horde fleet in outer space, special boots that enabled flight were designed and handed out to the Morituri.

[4] Initially, Scatterbrain could only transmit psychological conditions, ranging from drunkenness and sobriety to fear and nausea, albeit in an unfocused manner, often affecting his own teammates if they were in the vicinity, against his own will.

[5] The team realized that something was horribly wrong and they visited the Morituri base, where they witnessed the results of the operators' carelessness.

After Scatterbrain's powers vanquished the Hordians, fellow member Silencer euthanized the monstrous Morituri, relieving them from their misery.

Seeing only darkness and pain, an agonizing Scatterbrain lashed out with his psychic powers and inadvertently killed the remaining Hordians.

"Scatterbrain" warned him of the "new ones" (the alien race known as VXX199), the conspiracy of the corrupt politician Andre Lemont, and his teammate Shear.

[10] Ten years after the conspiracy was revealed, Scanner was again visited by the ghost of the late Scatterbrain, who warned him of the VXX199 and their subtle efforts to take over the word.

[11] Eventually, this new "Scatterbrain" revealed he was an artificial intelligence, which had been developed by the United States of America in late 20th century, for military purposes.
