Loki(s) versus DC Earth

Loki (current per Fraction/Gillen)
Loki, Lord of Asgard (per previous Thor volume's "Ragnarok" arc)
Ultimate Loki
Loki (JMS run)
Loki ("The Reigning" Alt. Reality)

versus

Current DC Earth (barring High Skyfather and beyond interference)

1. The Lokis have 72 hours of prep.
2. The Lokis have a year of prep.
3. No prep.

Team Loki is working together and will not betray or backstab each other for the purposes of these encounters. PIS off, CIS (save the aforementioned stipulation) is on.

John Constantine. End thread.

How would he win?

Wait does DC know they are being invaded or whatever. If Constantine gets time to prepare, he can likely defeat them. Or at least some of them.

DC Earth has no prior knowledge.

Hm, it's harder without everyone being familiar with WW. Current Wondy has her lasso, but most of the other heroes don't know that. She'd be a pretty great weapon against Lokis normally.

This is definitely a job for the mystic heroes.

Blue Devil and RAGMAN!!! That is all.
