He’s not Batman — he’s Superman!

Ben Affleck showed off some impressive climbing skills on Thursday by scaling a security fence after he and girlfriend Ana de Armas arrived home and apparently found themselves locked out. He even kept his face mask on while hopping the gate.

The lovebirds had come back from a neighborhood stroll with two dogs in tow.

He also showed some hometown pride wearing a T-shirt reading “Believe in Boston.” ‘

Earlier this month the couple made their relationship Instagram official when the “Knives Out” actress posted a series of photos of her with Affleck while celebrating her 32nd birthday.

Affleck, 47, first met de Armas on the set of their movie “Deep Water” in New Orleans.

In March, they were spied vacationing in Havana, Cuba and then later enjoying the beach in Costa Rica. Since then, they’ve been quarantining together in Santa Monica where they have been snapped picking up coffee.

Page Six has reached out to Affleck’s rep for comment.
