Could the heroes of Invincibles earth defend themselves from Galaxtus

Random Scenario: On his way to devour Earth, Galaxtus was unexpectedly teleported to the Invincible universe along side his herald Terrax, but he still sets his sights on earth. Can the heroes of earth stop this attack or will they die a quick death.

Everyone is here including heroes long since fallen and villains like Tragg and his kid army, Conquests, and other dimensional Marks.

And I’ll use EOS Mark.

The main goal is to protect the earth and drive away Galaxtus.
