I don't really know about the stats, but considering that the DR of 404 with his Dark Blasters is 750, then I would say that the DR of 404 with his God Ray is 1,500 giving him an Attack of approximately 6,000. Whereas his Defense, 404 is never said to have anything special in terms of defense, but he has his Fiberglass SOUL, that's why I give him 50 to 100 Defense. With this, the rest could be calculated as Infected, having perhaps an Attack of 5,000 with his God Breaker and 5,000 Defense with his Unrivaled Defense. That would give Infected in his Soul Harbinger form maybe 20,000 Defense and 20,000 Attack, an adequate power, Omni maybe 22,000 Attack and 15,000 Defense. Another might have 10,000 Attack when he opens both eyes and 100 Defense.
Also Fiberglass SOUL should not be used as a source of calculating defense. It is just able to deflect pretty much any attack. Infected stats are listed in character box and also omni can lift 2 moons easily.
