We have yet to see The Black Cat encounter Tigra. I long to see Greer's reaction towards the changes in Felicia's behavior. Afterall, Tigra was Spider-Man's first female crime fighting partner. Thus, Greer might be concerned about the changes of Spider-Man's former partner. It would be cool to see Greer helping Felicia to find herself once again. I would love for Greer to knock some sense back into The Black Cat once again.
Tigra vs Black Cat would mirror Cop vs Crime Boss takedown...
