Thunder Guardian

Thunder Guardian is currently the only three-part Biklone in the series. It consists of Mega Beast Clones Argentavis, Mammoth, and Giant Elk. Biklonauts Mio, Pio, and Teo all control this Biklone, while the machine is managed by sysops Toxy, Shade, and Silver.

Thunder Guardian carries everything it needs on its back: its shield, its weapon, and most importantly, its jetpack. Every guardian should have a jetpack.

Attack Lineup
Thunder Guardian's defensive option, consisting of Argentavis's body and the Disc Chip. While the shield is rather large even on its own, when it is activated, a giant energy barrier is created around it, further increasing the blocking range. When the shield takes a hit, it releases a shockwave that pushes nearby foes back, and if an enemy hits it on its own, it is stunned upon contact.
 * Thunder Shield

The Thunder Shield can still be active even when Thunder Guardian itself is not holding it, meaning that it can be passed on to an ally, like Cross Attacker, and that ally can use it to its full extent. However, the Thunder Shield is not completely invulnerable, and attacks that are strong enough can break through the energy barrier and damage the shield itself.  Thunder Guardian's main offensive option. The Macuahuitl is, well, a macuahuitl, which is in fact a real thing! The weapon consists of the Mammoth clone's head and unleashes its blades when activated, with long, spiked blades on the Mammoth clone's trunk and stubbier ones that more resemble real macuahuitl blades on its tusks.
 * Macuahuitl

Thunder Guardian typically uses its Macuahuitl to fling energy spikes at enemies (which, unfortunately, is not something a real macuahuitl can do), which explode on impact. The spikes regenerate quickly, allowing Thunder Guardian to attack in rapid succession. The Macuahuitl is also understandably a very heavy weapon, and thus can also be used like a club to smash foes in close combat.  The finishing move of Thunder Guardian. It is activated by Mio, but has never been seen in the series. Supposedly, it would involve using the Argentavis clone's jets to increase the speed and power of the "kick-outer"-ing, which would explain why Mio activates the move.
 * Guardian Kick-Outer

Guardian Kick-Outer was almost attempted in season 4, but Mio hesitated briefly, allowing the enemy Bulgasaris to escape.

Toy
This is a three-pack of the Argentavis, Mammoth, and Giant Elk toys, with their disc chips being swapped out for a Thunder Guardian disc chip. Once combined, the soundbox in Giant Elk will activate, and the toy will play sounds when the blue button on its head is pressed.
 * Mega Beast Thunder Guardian/메가비스트 썬더 가디언 (2015)
 * Accessories: Thunder Guardian Disc Chip

The sounds are as follows:


 * Biklonz Mega Beast! (when combining, when button is pressed after an extended period of time)
 * Mega Beast, Thunder Guardian! (Mio, Pio, Teo)
 * Macuahuitl! (Toxy, Shade, Silver)
 * Thunder Shield! (Toxy, Shade, Silver)
 * Guardian Kick-Outer! (Toxy, Shade, Silver)

Thunder Guardian's articulation is limited, with the arms only moving forward two clicks (though they are pretty big clicks), while the biceps swivel and bend, the wrists turn, and the hands open. The legs can move forward and the toes can bend down, but there is absolutely no way to use that for proper posing due to the massive weight of the figure. The hands also have trouble holding its weapons; the Thunder Shield will stay, but the Macuahuitl is best left perched on Thunder Guardian's shoulder while it holds it.

With all that in mind, it is still a very large, heavy, and imposing figure that singlehandedly rivals the mass and size of Biklone Infinity on its own.

Trivia

 * As development for Biklonz: Attack of the Bulgasari has seemingly halted, Thunder Guardian does not have any data to show for the game.
