• Chris Evans has added plenty of tattoos to his body over the years, but most of the time, they're concealed.
• Many fans recently became aware of the Marvel star's ink after he posted a video of himself shirtless and backflipping into his pool.
• Evans has a matching tattoo with four of his "Avengers" costars, an eagle on his chest, and a design dedicated to his dog named Dodger.

Chris Evans may have surprised plenty of fans when he recently showed off several tattoos in a video of himself backflipping into his pool, but he's actually had ink for years.

Although the 39-year-old Captain America actor has had a fair share of shirtless scenes in films like "Not Another Teen Movie," "Fantastic Four" (where he played another Marvel character, Human Torch/Johnny Storm), and "Captain America: The First Avenger," his various tattoos were covered by makeup.

But a few of Evans' designs have appeared in some of his early movies in Hollywood.

Because Evans typically dons full designer suits or casual long-sleeved shirts during public appearances, it's often difficult to see his ink.

But eagle-eyed fans have caught glimpses in the Marvel actor's interviews, social media posts, and images snapped by paparazzi.

Here's a guide to Evans' ink, plus the stories and potential inspirations behind them.
