Manny Pacquiao runs the Hajime no Ippo gauntlet

Manny Pacquiao and the combatants get 4 months prep before each fight. 
 
Manny Paquiao fights against: 
Featherweight Gauntlet 
1. Ryuchi Hayami 
2. Featherweight Ryo Mashiba 
3. Ichiro Miyata 
4. Prime Eiji Date (with his experience leading up to his retirement fight) 
5. Japan Champion Ippo Makunouchi 
6. Prime WBA Featherweight champion Ricardo Martinez 
 
Upper weightclass gauntlet: 
1. Masaru Aoki 
2. Tatsuya Kimura 
3. Bryan Hawk 
4. David Eagle 
5. Mamoru Takamura

It's practically been 4 and a half years, but I feel like thread necroing so...

SPITE. Pacquiao stands no chance

Prime Pacquiao would easily beat almost all the featherweights. I don't know what it takes to beat Martinez yet, so I don't know who would win between Martinez and Pacquiao.

Stops at Bryan Hawk

lol

Cleaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrrrrrrrrrrrrrrrrrrrrrsssssssssssssssssssss!

Ahhh... realistically or by anime/manga feats? Assumed weight equity?

Stops at Martinez. That guy is broken.
