My Crash still has it's share of work. I haven't even begun to touch the head, and have plenty to touch up with the hands and feet. I feel Lucario made an excellent base for this, but Sonic has his own respective advantages, as does Fox.
I plan to build a moveset, but unfortunately Lucario lacks the diversity necessary to make an interesting one. Sonic, in addition to having ideal hands and feet to build off of, has an Up Special I would like to modify in to the one I want for Crash (Transform the spring in to the bouncy box)
Let us all put a valiant effort in to this, and may the best Crash win!
