The term "broad" is not always pejorative

Grace- She Hulk

I only know of first character from innuhnet perusal and not through any purchased comic books, and thus have no comment other than that she seems to be similar to character I’ve paired her with.

But She-Hulk? Here was a character created to secure a copyright, and as such was initially played as a distaff version of the Hulk: she’s beset by berserker rages, which she bemoans in human form etc etc. But then Roger Stern, who wrote the Avengers through most of the 1980’s, got ahold of her. He had the bright idea that maybe She-Hulk likes being green, super-strong and voluptuous, and can easily reconcile all that with a career in law. And that’s what has made her easily one of Marvel’s most important and beloved female characters since.

I would put have her with Power Girl if PG had not been reestablished as a Kryptonian. So this one’ll do…

Commonalities:
Two very tall, super strong women with prodigious sexual appetites that neither see any need to apologize for.

Differences:
Only that Choi was born with her abilities, and Shulkie got hers from a blood transfusion from her cousin, Bruce Banner. And Choi is nowhere near as prominent a character…

Alternate histories:

GR: Grace Choi receives a blood transfusion from her cousin, the Blockbuster: she is consequently granted with tremendous strength. She joins the Justice League for a short time before briefly replacing Robotman in the Doom Patrol. Choi has since worked the Justice League a number of times and now serves with the Outsiders.

SH: Jennifer Walters is a young woman whose tremendous strength manifested itself in adolescence; she recently learned that she is related to the Femizons of the 23rd century. Known as She-Hulk, she has spent her heroic carreer with the Defenders.
