So according to Starlin (Thanos) Annihilus 2.0 is easily equal to Thanos yet still loses, apparently Gladiator is easily as formidable as Hulk yet gets stomped, while the Hulk fight with Annihilus was inconclusive. Also apparently Thanos vs Gladiator wouldn't be an easy battle, yet Thanos vs Anni fight indicates that it would be an easy stomp in favour of Thanos. Makes sense.
Can't take his stories serious these days, the level of wank and bias is obvious whenever he writes Thanos.
