Tricky – I’d say the Rev-9 just from being able to duplicate and its agility… plus it has a longer battery life. The pede needs to recharge.
A GROUP of them though? then they’d be able to rotate and mulch – after all, they had the vamps AND a were on the ropes initially. But the swordbreaker shows their weapons are vulnerable. A Rev-9 just has to use something similar and it can face down a one on one. If the Pede can injext something corrosive into the machine that its nanites can’t handle, then they’d have an issue. A group of Pede’s would probably win.
