These are not the kind of rivals you want to burn.

The brother of notorious drug lord Pablo Escobar has threatened to “take down” Elon Musk with a $100 million lawsuit for stealing his plans for a flamethrower, according to a report.

Roberto Escobar, the 72-year-old former accountant for his late brother’s Medellín Cartel, alleged to The Telegraph that an engineer for Musk’s company stole the idea during a trip to the Escobar compound in 2017.

He claims the idea of a “toy flamethrower” came from the way the Escobar brothers would burn their mountains of cash to keep warm — insisting that the model being sold by Musk is actually their copyright.

“We will soon file a $100 million case against him in America, and I will try my best to make sure he loses his stronghold in Tesla Inc.,” Escobar told The Telegraph.

“He knows exactly what he has done to us.”

Musk’s The Boring Company started selling its model last year, calling it Not-a-Flamethrower to overcome customs regulations against transporting flamethrowers. Though the device is not currently for sale, the website claims more than 20,000 have been purchased.

Escobar’s model, meanwhile, is advertised for $249 on a website showing a bikini-clad model using one.

Escobar claims the alleged theft proves that the Tesla founder is even worse than his kingpin brother, whose cartel monopolized the cocaine trade into the US before he was shot dead by officials in 1993.

“Elon Musk is a person that betrays people. Pablo never betrayed anyone,” Escobar told the UK paper.

“People only betrayed him. This was their mistake, and usually, it cost them their life. Such is nature.”

Escobar reportedly settled with Netflix in 2017 in his lawsuit over the hit show “Narcos,” which was based on his brother’s life, telling The Telegraph, “Nobody stops Escobar.”

He now claims to have a secret new product that he believes will destroy Apple.

“I need around four years to make it bigger than Apple,” he told the paper. “Things move fast in technology. Within the next month we are going to launch our first product, I cannot tell you what it is, but it will be much better than anything Apple ever did.”
