A human Perry could be shown as having a very strong sense of justice, just like he does as a platypus.

In the fanfiction, Perry as a human could have a secret lair just like he does as a platypus. But instead of being hidden in the bushes, it could be in an abandoned building.

And he would use it as a base to plan his missions to stop any evil plans in the human world.
