The Undefeated Enemy

Everything's all fine and good for them until a certain somebody had to come along and ruin everything.

The opponent who the Hero or Main must face as a final challenge and has a perfect record and very good reputation among their fans. If we can get a look at them in action, we'll see them destroying their rivals without breaking a sweat. The protagonist who has to take them on is intimidated by this, but they must push on and face their biggest challenge yet. At first, it's a Strong v Weak match and the audience (not us) doesn't believe in our character at all, but as Plot Armor is on their side, they most likely win the game using their God-Send Skills and ruined their foe's record and rep. The Un defeated Enemy might report them for hacking and violently demand a rematch after this undesirable outcome.

An Undefeated Enemy may also appear as the Final Challenge for the Main Sports Team before they can win a championship or other prestigious competition. The Enemy, in this story format, is an unstoppable rival team who has crushed everyone who got in their way, carrying a perfect record with them the whole journey. The members of this team are all likely going to be fearsome monsters (figuratively) whose equipment crumbles to pieces under their raw might. Even though the Undefeated Enemy could rip the Main Sports Team (and anyone else for that matter) limb from limb, our heroes force themselves into their next and last face-off in hopes of taking the trophy home as the game ends.
