While under the influence of the Hero Booster Program, the move is upgraded to the Bloody Thunder Vortex Strike
This is considered as Mr. Big Horn's Killer move as he rides a stampeeding longhorn steer at his target. Combined with the steer's horns and his own, Mr. Big Horn is able to deliver a massive strike to his opponent, (though Fatman was able to survive it). Once he was under the influence of the Hero Booster Program, the move becomes possible without the steer and adds a twisting motion as well. This is called the Bloody Thunder Vortex Strike with larger, more deadlier horns and far greater ramming force.
