Are “SPECIAL MOVES” purely the realm of video games…or is there a real life application for them?

And, I’m not talking throwing bolts of lightening and fireballs, or electrifying your skin…although if those are possible, I wouldn’t mind knowing.

But, is it advantageous to practise specific sequences, that suit my style and play to my strengths, with the aim to execute them in a real situation.

Or, are such sequences always too clumsy to implement, and make you vulnerable to good opponents who pick up the sequence, then predict your moves…and naturally counter attack?
