The 26-year-old made followers squirm when he shared a smiling action shot, showing himself covered in blood while holding up a massive catch.
Tom and Nicole's son rarely comes out to play, so seeing him in his element is a real treat.
In the photo, Connor is seen on a fishing boat next to his friend, fellow fisherman, and attorney Captain Jack Vasilaros.
Keeping it casual for their day out on the sea, Tom and Nicole's adopted child wore a gray hoodie and light blue shorts.
Unfortunately for Connor, the color of his shorts couldn't hide the bloodstains from the ginormous fish he and his partner caught.
No amount of blood could bother Connor and his buddy while they showed off their prize.
Barefoot and proudly holding up their catch, the duo flashed their pearly whites for the photo opt.
"Happy Birthday @hookedforlife," Connor wrote, adding, "Cheers to another year slaying monsters around the globe."
It's been two months since Tom Cruise's son blessed up with an Instagram post.
Showing himself with a fresh cut, Connor revealed he had lost his signature bushy beard. He also buzzed his curly hair.
Tom and Nicole's oldest son looked completely different than we've ever seen, and he couldn't wait to show off.
"New face, who dis?" he captioned the selfie, which sparked a firestorm on social media.
Connor lives a fairly private life and reportedly remains close to his father and the Church of Scientology.
Tom and Nicole adopted him not long after he was born in 1995, but he wasn't their first.
Before adding Connor to their tribe, the Academy-Award winning couple adopted Isabella Cruise, who is now 28 years old.
Nicole's relationship with both children is reportedly strained due to their Scientology ties.
The Perfect Nine Strangers actress opened up about Connor and Isabella during an interview with Australia's Who magazine in 2018.
"I have to protect all those relationships. I know 150 percent that I would give up my life for my children because it's what my purpose is," she said. "They are adults. They are able to make their own decisions. They have made choices to be Scientologists and, as a mother, it's my job to love them."
