There's no denying that Deadpool and his BFF Cable have a complicated relationship. They're friends, enemies, partners, and sometimes it's hard to tell which is which. But despite all their fighting (and there has been a lot of fighting), they've always had each other's backs.
Cable is a time-traveling mutant warrior from the future who was sent back in time to prevent a disaster. As such, he takes his mission very seriously and doesn't suffer fools gladly. Deadpool, on the other hand, is a wise-cracking mercenary with a healing factor that makes him virtually unkillable. He often jokes about death and violence, something that Cable finds frustrating but also endearing.
Over the years, these two unlikely friends have saved each other's lives countless times and formed an unbreakable bond. So when people ask who Deadpool's BFF is, the answer is clear: it's Cable!
