GO EMBER!!!!!!!!!!!!! I've never been that big of a fan of Jenny (then again I've only seen like 3 episodes in that TV show so I really can't talk and my OC for DP is based off of ember as they're half sisters so I would of course vote for my sister)
though Jens attacks are all mostly melee Ember could simple phase though them.
then again with a ghost that is basied on sound attacks Jen would have a slight upper hand since she really has no true ears as mentioned before...hmm..though the soundwaves will hurt as it has been proven before.
anyway its an interesting combo supernatural vs science and of course the classic good vs. evil :3
It would be Jenny. Jenny not only an arsenal of different weapons, the intelligence of a super computer and the physical strength she is also probably fire proof and she can turn Off her audio sensors (ears). Point jenny.
Ember may have the advantage, since Jenny flight can be mess up if ember plays a certain tune. This will make Jenny grounded, how ever Ember weakness is that her powers based on crowd attention. Jenny as more then enough tools to catch to take take the spot light. it will be a good long range fight. Good idea for a match where is the location?
