black cat is faster, has better reflexes, andis more agile...
depending on which representation of night thrasher, NT is more durable, and that's about it.. he doesn't even hold much of a skills advantage if any at all..
I'll say black cat for the win... for now...
She's just got toe many impressive displays, having tackled spiderman, dodged his webbing, toe to toed with carnage even if it was only for a short minute.
I've seen NT do nothing impressive but get stomped by 3rd rate gimmick villains who we never saw again.
