Traditional martial arts contain particular 'moves' specific to the human body and so may not translate well to other theoretical alien races. So is there a martial art which is theoretically suitable for all sentient beings? Yes, it is the meta-martial art called 'Shhhhh'.
Shhhhh contains no moves within itelf just a set of universal guiding principles which help the practitioner discover and perfect their own moves. All tactical and strategic variations are based on a small number of elemental tactics.
