Supergirl, Batman, Hal Jordan vs Thanos

If Batman has 2 weeks of prep time, and he has assistance from Supergirl and Hal Jordan can they defeat Thanos if he has only 3 days of prep time ?

Hal solos. Supergirl solos. Chew-Force Batman solos.

No

yeah lol

This is a waste of my time. Dc STOMPS.

2 weeks for batman is at least red death.

Supergirl can solo, Hal Jordan can solo handily. Batman with such prep is overkill
