Thanos is a Uber Genius he has 10 days of prep against Parallax & Ion can he win.

He has these Accessories Cosmic Cube,Sanctuary II,Dreadnaught-666,Stasis Rifle,Robotic Drones and Terraxia & Fallen One

Cosmic Cube? Isn't that quite unfair?

Maybe in 10 days he will again try to find somehow the power of HOTU, the he will win, otherwise no!
