User blog comment:BeastMan14/Urdnot Wrex vs Captain Rex/@comment-4248317-20121118062529

I think Wrex's training needs to be higher.

Regardless, Wrex gets my vote. Krogan are some of the toughest fighters in the ME universe, able to take unbelievable amounts of punishment (including, according to Wrex, being able to survive the vaccume of space due to their redundant nervous system). Captain Rex may have been bred for war, but Wrex's entire culture lives for war, enduring far greater threats than anything the clones have seen. Not to mention, his biotics will catch Rex off guard, so even if he is somehow disarmed, he can still fight from a distance. Rex's forces may outnumber Wrex's in this fight, but against a force of 5 Krogan, including a battlemaster, the clones would need a lot more troops to have a chance.
