OMG!!
Thanosi's logic is SOOOO bad in #2 that it defies belief...
And he still ducks the question; over the course of the SEVEN PANELS it took for Thanos to get back to his feet, what was there to prevent Odin from stabbing him through the neck with Gungnir and taking his head off!? Again, not a dam thing...
Also, ODG in the Odin/Mangog vs DP Tyrant/Thanos already proved that Tyrant is a bad matchup for Galactus because he literally eats (and amps off of) Galactus's attacks...so using that as a metric of how tough DP Tyrant is makes for poor logic as pertains how he'd do against Odin.
Last I looked, Odin's power is NOT based upon BSE...so there is no reason to believe that Tyrant would eat Odins attacks or be able to amp off of them as he's able to do against Galactus.
