The V-Rex
He is a marvellous big beast. He stands 76.7 meters tall, is 117 meters long, and weighs in at 8500 tons.
Now, he has 1600 ten thousands horsepower to Time Robo Alpha's and Beta's 1500, though he's beaten out by Shadow Alpha's 1800. The Time Robots' Blizzard-slash attack and V-Rex's Max-Blizzard attack are both at 1000 PP. The Rex-Laser outdoes the Flier Magnum at 800 PP to 600 PP.
He is controlled by Time Fire through the V-Commander:
F1 operates those huge cannons on his shoulder for the Max Blizzard attack. F2 signals the left hand's Rex Punch. F3 commands the right hand's Revolver Missiles. Now to command it, one holds in VC and hollers into the microphone. I'm reasonably sure the other three buttons are go, spin and stop.
