Suggested by Destroyer Havok has powerful energy blasts that can even rival Cyclops. That said, Juggernaut has built his whole reputation around having insane durability and raw power. Havok’s not going to really be dealing any lasting damage to him. Juggernaut will just power through the blasts and crush Havok in the blink of an eye. There wouldn’t be much he could do against that. Juggernaut wins.
