No she didn't trash her. She was the stronger out of the two but not by leaps and bounds. Gamora held her own and the GOTG jumped in and pretty much ruined any conclusive victor in their match. Angela however did compliment her on her fighting abilities. Also it should be noted that it was also Angela's first real battle in the MU so there's also that.
In that case Angela by proxy doesn't belong here either which would be incorrect. With the amp Gamora may just be too much for anyone on the field. I don't understand why you would say that Gamora doesn't belong. Maybe that's what i should have asked in the first place.
If Angela was really far above Gamora without the amp, she would have destroyed her in one on one combat. She did not because she could not. Angela had the edge in power but she it wasn't to the point that Gamora was helpless. Gamora gave as good as she got.
With the amp she fought Angela while she was in possession of Mjolnir to a stalemate. This shows me that the only person on T2 capable of keeping up with Gamora is Angela, because the other 2 have yet to show what they can do.
1. So Gamora without the amp can keep up with Angela without Mjolnir.
2. Gamora with amp can keep up with Angela with Mjolnir.
3. Gamora's amp indicates that it gives her the power to compete with Thor.
Zarda is in question here, not Gamora even without the amp.
