VERY Amped Superman runs Gauntlet
Sundipped Superman (1 week in the sun) with a GL Ring, Wonder Woman's bracers and Thor's hammer. He also is wearing Ultimate Magneto's helmet, which prevents telepathic attacks.
(before the fight, and before he sundips, Supes gets 1 month to train with his power ring, and one month to train with Thor's hammer).
Superman is not holding back at all.
He gets to fully refresh between each fight, gets to recharge his power ring, and gets a fresh week long sundip between each battle.
1. Drax with the power gem and WWH

3. Green Arrow (with kryptonite arrows), Batman (with Kryptonite gloves), Iron Man in Thorbuster Armor, and Hal Jordan
4. Voided Out Sentry

NO BFR in any fight.
Keep in mind the WW Bracers can completely block blasts from multiple skyfathers at once, and with Superman's speed, and the hammer's absorption powers, it will be really hard to hit Supes with any sort of energy blast.
