Dengar vs. Clone Commando
Hmm... I have read Payback: The Tale of Dengar and Republic Commando: Hard Contact. The Commandos have top-grade training and extremely good armor. I'd like to say the Commando. But Dengar can't feel pain, exhaustion, any feeling but hatred. His eyes can magnify enough that he can clearly see things that are a mile away and he can move extremely fast (he ran a mile in a few seconds 😱 ). When shot at by some Imperial dude at the beginning of Payback: The Tale of Dengar he dodged a blaster bolt by moving to the side and then moved back so fast that the Imperial thought the bullet went through him! Now that's fast. So if the Commando can hit him then it wins. If not, well, it'd take many shots to kill the Commando.
