By defeating the 8 bosses, they will be added to the list of playable fighters and can be chosen in each mode except for the league mode. First you play a league challenge against a JR class wrestler. Be sure to win all six divisions with the same wrestler and then face the boss. If you won, there will be a new division called Super R. Be sure to win this too and you will face a secret fighter called Jaguar. Be sure to carry out the same for the heavyweight class. You face the same bosses during the 6 divisions. When you defeated them there will appear a new division and also a hidden fighter.
