World's Strongest is an achievement/trophy in Midnight Club: Los Angeles.
Acquisition[]
Defeat Marcel, the Muscle Champ in a one-on-one duel. The mission spawns after winning 35 races with a muscle car (after unlocking Group 4 vehicles) and becoming the City Champ.
Tips/Strategy[]
In order to challenge each of the Vehicle Type Champions, you will need to win 35 races with a vehicle type after unlocking the Group 4 vehicles at Champion Rank (16,500 Rep).
You will also need to become City Champ for these missions to spawn assuming you met the requirements.
For the Muscle Champ, you will need to win 35 races in a muscle car after unlocking the Group 4 vehicles, and have defeated Booke as the City Champ in order to qualify for the Muscle Champ Duel.
Upon defeating Booke and having at least 35 Muscle wins post-Group 4 unlock, the player will receive a call from Marcel, telling him that he wants to race the protagonist in a one-on-one duel. The player must drive a Muscle car to be able to challenge Marcel for his title.
Defeating Marcel will reward the said trophy/achievement.
