Year-One JLA vs. Original Avengers

No preptime. No outside influences.

Lineup for JLA:

Martian Manhunter
Aquaman
Green Lantern
The Flash
Black Canary

Lineup for Original Avengers:

Iron Man
Wasp
Ant-Man
Thor
Hulk

REMEMBER. THE MEMBERS ARE AT THE LEVEL AND POWER AT THE TIME THAT THE GROUPS WERE ACTIVE.

Hmmm...the lack of a telepath is hurting the Avengers. Manhunter thins their ranks (probably to Thor and Hulk) and then the JLA mops up.

JLA would quite easily win this.

Not easily, but they would win indubitably.

The Avengers have Thor and Hulk. Thor and Hulk could beat those 5 JLA by themselves.

MM controls the Hulk. Hulk and the JLA beat the Avengers up.
