Trivia

 * The Xenoship, Protojet, Air Lancer Jet, Sickle Ship, and the Flying Darkwing Spector are all able to be made by connecting four different toys each. (Protojet - Tributon, Kutor, Leinad, and Bravenwolf, Xenoship - Vilius, Rho, a Hos, and a Sho, Air Lancer Jet - Lydendor, Valorn, Senjo, and Tavox, Flying Darkwing Spector - Viklips Trooper (Rho), Gatox, Gearnox, and a Gilltax, and the Sickle Ship - Granox, Slyger, Shadius, and a Sho)
 * All current Tenkai Knight Titan Fusions incorporate Bravenwolf, but only one has him as the upper body.
 * Dromus is currently the only Knight that haven't used Titan Fusion or Robofusion.
 * It is unknown if the Beast world robofusions will appear again.
