Melissa says on-panel to Mach-1 back in Thunderbolts v.1 #21 that she did not receive augmentation from the Power Broker like the other Grapplers (Letha, Titania, and Poundcakes, at that time). People constantly overlook this.
Also, as you say, she has never exhibited any sign of super strength in any of her other appearances, either. So between those two things, I still do not understand why some people assert that she was an augmentee.
I've been catching up on the new Wasp title and... what the heck is going on with the Grapplers?
One of them comments in #2 that they've had to work out in the gym for their buff physiques and wrestling prowess ("We're not all She-Hulk"), but... they are literal superhumans who can lift cars 'n stuff. They might not be on She-Hulk's level of super-strength, but they sure have managed to hold their own against other superhumans like Captain Marvel, Quasar, the Thing, and Bill Foster.
And I'm still not over the fact that Letha has done a completely unwarranted turn to good. She's flat out evil as hell; she killed tons of innocent people in an attempt to get to Punisher when she was first revived. It's not as if she's just some lady wrestler who wanted to live a normal life. She seemed to enjoy it with her lover Lascivious (who is nowhere to be found here).
It's just mind-boggling that either the writer did literally zero research on the characters (they're a wikipedia click away) or didn't care and just wanted to redeem some D-List female villains.
Any signs that they want to reconnect with old teammate Screaming Mimi/Songbird?
