Revealing new moves in Bruno's presence was unwise. Admittedly, the evolved warrior was on the other side of the battlefield, so his senses might not reach Khan's position. However, playing it safe had often worked in Khan's favor in the past. Actually, exposing himself had only brought problems.
Nevertheless, Khan couldn't care about those limits anymore. It wasn't only a matter of his element's nature, either. He was simply tired of compromises and ignoring what his heart wanted.
Besides, Khan had undergone torturous toxic pool training to achieve his current strength. He had paid a steep price to seize some political stability and enough power to fend off potential challenges. If that didn't give Khan the freedom to act as he wanted, he wouldn't see any purpose in getting stronger.
