The Illuminati had gone one step beyond and were mixing the gene splicing with their dimensional travel experiments.

After fighting the Illuminati and their Pokémorphs with the help of their own, the war seemed to come to a standstill. The HQDG decided to sign a ceasefire treaty with the Illuminati in 2193. However, they still monitored the Illuminatis activity just in case they tried to attack. Many rumours circulated around but they thought most of them were false or too crazy to work. This was until a division of the HQDG which was stationed near PNF-404 learned of the Illuminati superweapon and that it was being constructed on the planet. They activated the cloaking device and entered the atmosphere...
