Dressing as the Enemy

Sometimes the heroes will disguise themselves as the villain's henchmen in order to infiltrate the villain's lair and rescue a damsel in distress or a male damsel. This can also be to discover secrets from the enemy.

Disguise also led important role in dealing enemies as mere strength is not enough, as sometimes, the heroes would need to defeat them from the inside.

During the story, their cover or the disguise gets blown after the villains discover that the hero/heroine is an imposter.

Quotes
"(Toto leads The Scarecrow, Tin Man, and Cowardly Lion to the front of the Wicked Witch's castle where they hide behind the rocks.) Cowardly Lion: What's that? What's that? Scarecrow: That's the Castle of the Wicked Witch. Dorothy's in that awful place? Tin Man: Oh, I'd hate to think of her in there. We've got to get her out! Scarecrow: Don't cry now. We haven't got the oil can with us and you've been squeaking enough as it is. Lion: Who's them? Who's them? (The Lion points to the Winkie Guards marching around the front gate chanting.) Scarecrow: I've got a plan how to get in there. Lion: Fine. He's got a plan. Scarecrow:And you're gonna lead us. Lion: Yeah. Me? Scarecrow: Yes, you! I-I've gotta get her out of there? Tin Man: That's right! Lion: Alright. I'll do it for Dorothy. Wicked Witch or no Wicked Witch. Guards or no Guards, I'll tear 'em apart! Ruff! I may not come out alive but I'm going in there. There's just one thing I want you fellas to do. Scarecrow and Tin Man: What's that? Lion: Talk me out of it! (The Lion tries to slink away but the Scarecrow and Tin Man stop him and force him to lead the way.) (Much later, The Scarecrow, Tin Man and Lion are hiding behind the rocks outside the entrance to the Wicked Witch's Castle trying to think of a plan to get inside and rescue Dorothy. Unbeknownst to them, three of the Witch's Winkie Guards are sneaking up behind them. The Lion manages to spot them and tries to warn his friends but they ignore him. Suddenly, the Winkies pounce on them and there is a struggle. A few minutes later, The Scarecrow, Tin Man and Lion arise, somehow managing to steal the Winkies' uniforms, just as the rest of the guards start to march into the castle.) Scarecrow: Come on! I've got another idea. Lion: Do you think it'll be polite dropping in like this? Scarecrow and Tin Man: Come on! (The Scarecrow, Tin Man and Lion slip down the rocks right at the end of the marching line with Toto behind them. The Lion's tail keeps popping out and he desperately tries to shove it back in before anyone notices. Luckily they all manage to get in just before the drawbridge closes.)"

You're Bellatrix Lestrange, not some dewy-eyed school girl.) (RON: Hey. Easy.) (GRIPHOOK: She gives us away, we might as well use that sword to slit our own throats. Understand?) No, he's right.
