Chuck Norris' children share heartfelt tributes after his sudden death at 86

The martial arts legend's twins, Dakota and Danilee, each posted their own heartfelt tributes on Instagram, featuring photos of them with their father throughout the years.

Dakota shared a series of black-and-white photos of him with Norris, including one of the two of them sitting side-by-side when he was a kid, taken from behind, writing, "It's hard to find the right words for this, but I'll do my best."

"You've been the man I looked up to my whole life," he wrote in his caption. "Your generosity, your kindness, your courage, your integrity, your strength, your discipline, and your faith in the Lord were just a handful of things I always admired about you. You lived your life with purpose and with love for all people."

"Honest to God, I don't think there was a single day that went by where you didn't say it," he added. "I'm so proud to be your son. The memories we made, the lessons you taught me, and the constant laughs we shared will stay with me for the rest of my life."

Dakota concluded his tribute by thanking his father for "everything you gave to our family and for the example" he set for them, adding he hopes to "live a life that honors you and makes you proud."

"I love you, Dad. I'll miss you forever," he wrote.

His twin, Danilee, shared her own tribute on social media, featuring a series of photos of her and her dad over the years.

The post included pictures of Norris carrying her as a baby, the two of them sitting next to each other on the beach, one of her asleep on his lap as an adult and another of her asleep on his lap as a baby. She started the post by stating "Grief is a good enough word to describe" what she is feeling and that "losing a parent is something that you are never prepared for."

She described her father as someone who "loved so deeply and cared for every single person in his life with so much tenderness," saying that while "he may have a warrior exterior, but his heart was so full of love."

"To say how thankful I am for him being my dad is an understatement," she added. "He has been my safe person these past 24 years and I am constantly filled with gratitude for how much wisdom and love he has bestowed me and my brother. I will forever carry on his legacy and shower others in that compassion that he so frequently showed."

Danilee then thanked her father "for supporting me in all my passions and for pushing me to not shy away from the impossible," and for the "constant compassion" and love he showed her which "made me learn to love myself."

She concluded her post by writing, "I promise I will always and forever try to make you proud even if you already reminded me every day that it was impossible not to. I love you forever."

Norris shares Dakota and Danilee with his wife of nearly 30 years, Gena O'Kelley, whom he married in November 1998. He is also survived by his children Dina, Mike and Eric, as well as 13 grandchildren.

"To the world, he was a martial artist, actor, and a symbol of strength. To us, he was a devoted husband, a loving father and grandfather, an incredible brother, and the heart of our family. He lived his life with faith, purpose, and an unwavering commitment to the people he loved. Through his work, discipline, and kindness, he inspired millions around the world and left a lasting impact on so many lives."
