Mako used all of his fire-related skills that had a low cost and covered a massive area against the regular Terra beetles. Due to him expanding his reach over the many beetles who were charging at him as well as Bill and Leon, Mako couldn't just deal with one at a time and finish it off.
Instead, he used his abilities to steer and maneuver the beetles so that they would keep their aggression on him while Bill and Leon would be safe and protected.
Bill and Leon had the most difficult job as they continued to use their earth abilities to track the Beetle King's movements by sensing the earth's vibrations as the king moved around. Whenever they would get an opportunity, they would manipulate the earth surrounding the body of the Beetle King to conjure earth spikes and impale them on its body.
