Just for fun, on the Marvel side, the gals I can think of off of the top of my head, not being a comics nerd but definitely a fan of the movies...
Black Widow!!! ScarJo really sells that role!
Yelena Belova (had to look up her name). Loved her in Black Widow and the Hawkeye series
Speaking of which, Hawkeye's fangirl/protege Kate Bishop
Agent Maria Hill, the aforementioned Scarlet Witch/Wanda Maximoff, Agatha Harkness (for the MILF fans), Sylvie (female Loki), Carol Danvers, Jane Foster, Valkyrie (Valkyrie is a lot of fun!), Darcy Lewis, Sif (one of Thor's battle buddies), Frigga, Peggy Carter, Kate (Agent 13), Monica Rambeau...
Hela... she's kinda really scary powerful though!
Nakia, Shuri and Otoye (from Black Panther)
The whole X-Men angle (Storm, Rogue, Jean Grey, Raven, Mystique, Kitty Pride, Emma Frost, Angel Salvadore (works as a stripper in X-Men: First Class so yeah...), Blink, Jubilee...
Mary Jane/MJ (Zendaya's the more recent portrayal, Kirstin Dunst was fun too), younger May Parker (Marisa Tomei), Gwen Stacy...
Betty Ross, She-Hulk of course (upcoming movie/series), Christine Palmer (Doc Strange's love interest), Hope van Dyne (Wasp), Gamora, Nebula, Mantis...
Sue Storm-Richards of course!
I'm sure there are a number of others, but all of these gals that were portrayed onscreen are memorable to me in some fashion.
