To support my clames, I will use the pictures:

On the top, we see Kujas Hit Point bar. Above the bar we see LV 34 Kuja. On the bottem we see Zidane's Hit Point bar. Even though I accidently cut half of it off, I can see LV 23 Zidane Tribal

On top we see LV 51 Gardland. Bottem LV 38 Warrior od Light

We can't really see very well on the picture who is on top or who it is in the picture, but I can only assum it's Warrior of light or Sephiroth (I doubt it). On the bottem is LV 41 Gardland.

On top would be a LV 51 (Yes, I can see extreamly small text) Gardland. Bottem would be a LV 23 Zidane Tribal

On top is a LV 43 Warrior of Light and a LV 32 Kuja (? Things are in the way so I cannot be clear.)

Top: LV 51 Kuja. Bottem: LV 23 Zidane Tribal

Upper Right picture: Top is LV 51 Gardland. Bottem is LV 38 Warrior of Light.
Bottem Left Picture: Top is a LV 56 Zidane Tribal. Bottem is LV 41 (?) Warrior of Light.

Top: LV 38 Warrior of Light. Bottem: LV 25 Kuja.
There you go.
