May not want to limit yourself to a single character.

The more zany stuff they survive, the more likely they'll go crazy, this was deconstructed quite well in the movie "The last action hero".
-This is particularly true since here we jump from advanced sci-fi, to intelligent-critters, to medieval fantasy.

From TvTropes:
[quote]• Deconstruction: A fascinating form of it: While most action tropes are simply lampshaded to the point of lunacy when Danny is dropped into "Jack Slater IV", when the characters are turned loose into the Real World, Reality Ensues.

In one moving scene, still inside the movie world, Jack Slater reveals that under his Deadpan Snarker typecasting he's mostly just tired after repeatedly surviving implausible, stressful scenarios while everyone around him dies. Among other things, he's got a cashier at his drug store calling him at the police station so that his colleagues think he has a life and make everyone think his ex-wife still cares about him (she's remarried and moved on), and he's deeply depressed that his Action Girl daughter Whitney skipped her prom to field-strip an AK-47 (he fears she'll grow up alone). This is a side of Slater that Danny was shocked to see, but nevertheless, he was able to get him out of this funk to continue the action of the movie.
