Why not, eh? Might be a laugh.
Edward "Whitebeard" Newgate takes on the S Class Heroes of the One Punch Man universe. All fights take place on a deserted version of Malta. Whitebeard is in his prime with no health issues.
Scenario A: Gauntlet
Whitebeard fights S-Class in the order of their rankings in the S Class. He gets fully healed after each fight, how far does he get? King is missing for some reason (probably on some other important mission) and Blast is AWOL as usual.
1) Puri Puri Prisoner
2) Tank Top Master
3) Metal Bat
4) Demon Cyborg Genos
5) Flashy Flash
6) Watchdog Man
7) Superalloy Darkshine
8) Pig God
9) Drive Knight
10) Zombie Man
11) Metal Knight
12) Child Emperor
13) Atomic Samurai
14) "Silver Fang" Bang
15) "Tornado of Terror" Tatsumaki
How far does he get? Where does he stop? If Flashy Flash is too fast for him then he can skip because he is weirdly low in the rankings of S Class and makes the gauntlet a bit front loaded.
Scenario B: Whitebeard replaces Melzegard
Whitebeard replaces Melzagard and takes on the following in the ruins of City A.
- "Silver Fang" Bang
- Atomic Samurai
- Puri Puri Prisoner
- Metal Bat
- Iain (who will start with both arms but will get his feats from later in the manga as well)
Can he crush the team who are defending their planet?
Scenario C: Whitebeard Gets Hunted
Whitebeard takes on Hero Hunter Garou.
Garou will begin at the levels from when he fought Superalloy Darkshine.
Can the closest man to the King of Pirates take down the Human Monster?
