Former Rob & Big star Christopher “Big Black” Boykin passed away suddenly at the age of 45 on Tuesday, May 9. This tragic loss has got fans thinking about Big Black’s career and everything he accomplished.

So, who is Christopher Boykin?

He co-starred alongside Rob Dyrdek on Rob & Big

From 2006 until 2008 the comedic reality show aired on MTV.

Big’s skateboarding co-star took to Instagram to share an emotional tribute to his friend. In a snap that captured their fun and light-hearted time together, Rob and Big are seen swinging in a giant red swing with their feet up in the air.

“My heart is broken. I don’t want to write this post,” he captioned the post. “I don’t want to believe that this is reality. I am so thankful for you. We truly were brothers that lived an unexpected unforgettable adventure. I just can’t fathom that it would end so suddenly. You will forever be in my heart.”

Friction between the duo ultimately ended the show

Though Rob is clearly saddened over his friend’s death, their relationship was not always smooth and that led to the abrupt cancellation of their show.

“It was a strange period,” Rob said in 2016 regarding the tumultuous time leading up to the show’s end. “I had been a pro skateboarder for years, so me transitioning to mainstream fame was relatively smooth, right, where for [Big], the idea that man he was like working security two years earlier and now he’s on television, it was a much different dynamic. But I think we both struggled with I didn’t want to be known as like Rob from Rob & Big … and I think he didn’t want to be known for like the sidekick. So that created a lot of that tension between me and him.”

He lived up to his nickname

Weighing in at 375 pounds and towering at a staggering 6’6’’, it’s no wonder Christopher was known as “Big” to the public. His stature helped a lot with his career too, as it was his role as Rob’s bodyguard that got him media attention.
