Squires

From Ben10versepedia

Posing as a Little League Baseball team, the Squires and their coach, referred to only as Coach Finn, are robots manufactured by the Forever Knights as part of a plot to capture the President and replace him with a robotic double under their control. They knew that he would attend the finals for the Little League baseball season and would have the team win at any cost to ensure they'd be there to get him. The Squire robots are incredibly strong, able to bend metal bats with their bare hands and throw baseballs with enough force to punch a hole clear through solid steel. In addition, the Squires are able to change their shape and appearance to match that of anyone who they've been allowed to scan. The coach robot is even stronger, able to move faster than the eye can follow and equipped with laser cannons built into its shoulders. They were all destroyed by Ben.
