Nami Hulk.

From the surroundings, there are waves, but Nami is wearing what looks like wrestler's clothes, so I'm guessing she's fighting in an aquatic tournament. From her expression, she seems to be enjoying the fight and realizes that her opponent is a bit daring. Some Parts Of Her Body Are The Color Of Human Skin So I'm Guessing She's Started Transforming Now As A Way To Appeal To Things Seeing That Her Opponent Is Bold. I think she's saying the following. (Nami While Transforming Into Hulk) "I think I'm going to have to take this fight seriously."
