Rex was suddenly flung down, he looked back up when suddenly a kuni star was coming right for him, he watched to see the second assassin try and grab everyone, he quickly smashed his elbow into the assassin behind him, then flung him forward, smashing the star as well as him to the ground. He finished it off with a quick snap of the neck. He then looked to see how Tygra threw the princess off.

"You fool! What are you doing? Ever considered there might be assassin's outside? And the princesses safety is my only concern. Getting dressed was the last thing on my list!" 

He looked to Fang, or, the Fangs and smiled, he grabbed the other half of the star, and then threw it right back at her, then he ran up to another Fang while throwing his sword at a third. Once he reached the last Fang, he slid on the ground and went to do a kicking uppercut while the sword and star went for the other two.
