Ikeru Formula

The Ikeru Formula (originally known as "Midorikawa" and later referred to as the "Goblin Formula") was Japan's perverse attempt at recreating America's super soldier serum during World War 2. During their attempts at refining the formula, the Ikeru Corporation used it on many animals and insects and thus are responsible for Earth-21997's "Cross-species" hybrids. The formula had a green tint to it.
