I don't know why it took me so long to come to this realization, but Denise from DWW would "bring it" so fiercely and ferciously, with such stamina, in every event of hers that I thought she deserved a Top 5 Greatest Hits countdown.
Number 5--20-minute tribgirls session vs a blonde
This is a bit of a hybrid choice, as there's not really an actual fight. The women start on a couch, then take it to the mats, alternating between standup kissing and then on the ground scissoring. Denise is so ferociously the aggressor that it's a reinforcing reminder that when she IS all-out fighting, she's also getting aroused.
Number 4--Denise vs Jana, in jeans
This one was in front on a small audience, both men and other DWW fighters--wrestling-style rules. The look of the women's tops getting gradually shredded as the jeans remain firmly in place is priceless. The rules skew to Jana's style of fight, but Denise holds her own.
Number 3--Denise vs Jana, in a ring
This one is more catfight-style rules, and the girls appear to be alone. These rules are more Denise's cup of tea, and Denise wrecks Jana's hair ruthlessly. If the fight had continued another hour, Jana would have been a quarter bald. (Good job by Jana never once complaining.)
Number 2--Part 2 of Denise vs Anastasia
After beating the crap out of each other in nude MMA-style boxing (see Number 1 below), Denise and Anastasia engage in an extended make-out session, but with an atmosphere of animosity, not tenderness. And with Denise staying on top, allowing Anastasia only small stints of dominance.
Number 1--Denise vs Anastasia, nude boxing
In the scorching sun outside, as a special bonus. For 14 minutes, the two ladies simply wail on each others' faces with boxing gloves, landing haymakers with no thought to any defense. The hits are real, as Anastasia requires occasional standing 8-counts, to regain her balance and to count her teeth. Amazing that both ladies survived to complete the Number 2 sequel.
Denise has other material in her canon as well. But the above showcase her at her fiercest.
