America’s newest superhero is taking a beating.

Democratic politicians and late-night TV hosts unleashed an arsenal of snarky jokes following President Trump’s tweet dubbing himself a “Tariff Man.”

“Tariff Man, the worst superhero ever, raises your taxes and ruins our economy,” tweeted Minnesota Rep. Ilhan Omar.

Meanwhile, Sen. Tim Kaine (D-Va.) referenced The Beatles’ song “Nowhere Man,” tweeting, “He’s as blind as he can be. Just sees what he wants to see.”

In a series of tweets Tuesday, Trump warned that tougher tariffs could be on the horizon for China if Beijing doesn’t play ball on negotiating a deal with the US.

“China is supposed to start buying Agricultural product and more immediately. President Xi and I want this deal to happen, and it probably will. But if not remember… I am a Tariff Man,” he tweeted.

The Dow plummeted more than 800 points as doubts mounted about the US-China 90-day trade truce — but TV hosts had a field day.

“The superhero you never knew you needed,” tweeted CBS’ “The Late Show with Stephen Colbert,” along with a video titled “The Adventures of Tariff Man” — a spoof on the intro to the 1950s “Adventures of Superman.”

On “The Late Late Show,” James Corden suggested Trump had spelled “Terrible” wrong.

“I think the Marvel franchise has expanded a little too much,” he joked.

And “Full Frontal with Samantha Bee” referenced Elton John’s hit “Rocket Man” in a tweet.
