Component 326 is a green liquid substance. After getting in contact with Rex it causes him a "reversal to his original EVO form".
During a game of tag with Bobo in Doctor Holiday's lab, Rex accidentally spilled the substance on himself. Instantly Rex started to feel unwell. In seconds he went on a rampage destroying everything in sight. With Agent Six's help Bobo managed to reverse Rex to his human form by flinging insults at him - which caused Rex's bios to drop. Eventually the substance was presented to White Knight.
- Bobo notes that the component 326 stinks. Apparently it "Smells like [his] underwear."
