Take a character that never had a toy release and then design it around a different toyline.

ok
I didn't quite understand all the rules that
 TransformersFanclub gave me.
However I decided why not I chose Slipstream from transformers animated (she's the female clone of starscream) I turned her into a SPOTTED BAT/LEOPARD ..I wanted to stick with the flier thing ..so here she is in all her glory.

I hope i did well keeping to her original design and color scheme. :D
Below is the starter draft of my design Half Spotted bat/Leopard I don't know if this is what they are going for but this is what i got. :D
