A unique case amongst the serum trials, initial subjects expired within seconds, exhibiting major trauma to the body on scale previously unknown.

It was only after reviewing slowed-down footage of the initial tests that the team realized test subjects were essentially shredding their own bodies when attempting to move, the incident happening so fast as to be nearly indiscernible to the naked eye.

Highly diluted solutions were used for subsequent tests, with doses increased slightly until physical limitations were reached.
