You're in the game (5)	Create a boxer using the photo game face tool.

If you are curious to see what a boxer with "Kung Fu" would look like, that is how you do it. You can get skilled enough to be able to overcome a 100 lb weight difference, the heavyweight fighter being basically maxed when it comes to taking and giving punishment. If skilled enough, size truly will not matter.

Set the round time to 1 minute and up to only round 1. Just punch him enough to win by decision. This may also work for the "My Style Is Impetuous" achievement or trophy. Do the same while fighting Mike Tyson, but with a created boxer.

Set the rounds to 2 minutes and choose someone like Foreman. Keep blocking and punching. If done correctly you should knock them down and get the achievement or trophy after the fight.

Become the champion of two weight divisions in Legacy mode, then reach "G.O.A.T" status.

Win the Lightweight, Middleweight, and Heavyweight Online belts.

Start a new legacy. Win the tourney, then punch totals in the last fight. Press Circle to get +5 to Power, Stamina and Heart again. Repeat this until your stats are at maximum.

"Ring experience" does matter; the more you do Legacy mode, the better. If you combine a career spanning 1,000 fights, plus "500 years" playing the training games, you would get to see what a "perfect boxer" would look like.
