Johnny Walker

Johnny Walker is one of the UFC light heavyweight division's most electric wildcards, a long, rangy Brazilian who burst onto the scene with a run of spectacular knockouts and viral celebrations. His arsenal of flying knees, spinning attacks and one-shot power makes him capable of ending any fight in an instant.

That same explosiveness comes with defensive lapses, and his career has swung between dazzling finishes and abrupt losses against the division's elite. Through the ups and downs - wins over Anthony Smith and Zhang Mingyang, tough nights against the likes of Magomed Ankalaev - Walker has remained a fan favorite precisely because you never know exactly what you're going to get.
