One’s a fictional super hero.
The other is a true Super League legend. But there’s more than a passing similarity between Iron Man Tony Stark and former Huddersfield Giants star Luke Robinson.
The latter - who had to retire from the sport because of injury - is in the middle of planning his testimonial year.
And a big part of that will be a testimonial match with a special shirt for the players: a short that is uncannily like Iron Man’s superhero outfit.
Iron Man is a fictional superhero appearing in American comic books published by Marvel Comics.
The character was created by writer and editor Stan Lee, and has been brought to the big screen by Robert Downey Junior.
He reprises the role in the new film Captain America: Civil War, just released in cinemas.
The testimonial shirt, in claret and gold, includes what appears to be a glowing heart - much like Iron Man’s arc reactor, built into Tony Stark’s chest.
Robinson, 31, appeared for Wigan and Salford before joining the Giants in 2008.
He went on to make 221 appearances in front of the Claret and Gold faithful.
His first testimonial event will be a dinner at the Cedar Court Hotel on Saturday evening.
