Wanda Wilson, better known as Copycat in the comics, is such a fascinating character in the Deadpool universe! She's a mutant with the ability to mimic other people's powers and appearances, which makes her a perfect foil (and sometimes love interest) for Wade. In the first 'Deadpool' movie, she's reimagined as Vanessa Carlysle, a sex worker who becomes Deadpool's girlfriend. Their chemistry is electric—equal parts chaotic and heartfelt.
What I love about Vanessa's portrayal is how she matches Wade's energy without being overshadowed. She's not just a damsel; she's sharp, sarcastic, and fully embraces his madness. When she gets kidnapped, it triggers Wade's transformation, but the film avoids reducing her to a mere plot device. Later, in 'Deadpool 2,' she even gets a bittersweet moment that cements her emotional impact. Moretta Baccarin absolutely nailed the role—blending toughness, vulnerability, and dark humor.
