There was another reason why Luke had proactively joined the upper circle — it was because of the issue of equipment.
As he had speculated before, just like when he had gone to 2023 Marvel, most of his inventory had been 'left behind.'
The difference was that in 2023 Marvel, he could access about a third of his inventory.
The situation in DC was even worse, and he could only use one tenth of it.
For his main body back home, it felt like one tenth of Space 1 and 2 had 'disappeared.'
This completely eliminated the possibility of him using his inventory to move supplies and living people across planes.
It was impossible for the Marvel Bat Squad to enter a DC instance together.
DC had too many lunatic villains; General Zod's team alone was enough to torture Earth's heroes.
Also, there were DC comics and some movies from 2023 Marvel which Luke had skimmed through in the last few days.
