John Shepard is a capable fighter who is good with a gun and can even fight hand to hand if needed. That said, he won’t be able to keep up with Layla’s savage fight style. She will be able to quickly overwhelm him here. Not only does she have some trap cards at the ready but she even has other LRigs at her disposal. Their stats are all quite impressive and once Layla enters her berserk mode John Shepard will have no choice but to retreat. Layla wins.
