But if there's one thing I've learned from DBZ, it's to never let your opponent see your true power until its absolutely necessary
YES!
tip from my brother's who are mma fighters is:
When you go for a punch keep a very loose fist until the moment right before impact. Use your hips to punch. FOLLOW THROUGH! Dont tap him and then pull back. When you strike imagine you are punching 10 feet behind him. If you can get a good gut shot like this you could probably win in one strike. Dont punch him in the face like this unless your trying to knock out his teeth or break something.
