Claudius is a male lion who lives in a den at the Roman Colosseum.
Claudius is the champion of the many gladiatorial battles he has fought. Considering the number of lions the statue on top of his den represents, it's clear that he has been living in the Roman Colosseum for a while.
When Timon, Pumbaa, and Simba run into each other after being captured and taken to the Roman Colosseum, they plan to leave the arena for the nice vacation in Rome, only to be stopped by Colosseum Quintius, who tries to force Simba to eat Timon and Pumbaa, otherwise he will have to fight Claudius.
In order to avoid getting eaten by Simba and having their friend die in the battle between him and Claudius, Timon hatches a plan to make it seem like Simba is eating them. The plan, however, backfires as Simba is forced to spit friends out of his mouth after Pumbaa inadvertently passes gas.
Exposed for tricking Quint, Timon, Pumbaa, and Simba make a hasty retreat and they manage to escape the stadium, with Quint in pursuit. After a long chase that culminates to both groups using chariots to escape one another, Pumbaa manages to leave Quint behind, leaving him, Timon, and Simba to try and find a way out of Rome. Shortly after running around however, Quint surprisingly captures Simba and prepares for him to fight Claudius to the death the next day.
Unable to free Simba from his imprisonment, Timon and Pumbaa devise a plan to make Claudius forfeit his fight with Simba instead. Later that night, while visiting the lion's den, Both Timon and Pumbaa come up with various ways to make their plan work, such as asking favors, blackmailing, and teeth extraction, all which end in failure.
The next day, Simba and Claudius enter the Colosseum, prepared to fight each other. Suddenly just as both lions prepare to fight, to everyone's surprise (and the audience's frustration,) Claudius falls asleep. It's then revealed that while Timon and Pumbaa couldn't get Claudius to agree to not fight Simba, their attempts to make him forfeit did keep him up all night, without any sleep. Enraged that Claudius won't fight now, and that Simba still refuses to eat Timon or Pumbaa, Quint decides to fight the trio himself.
