If you guys ever wondering what is the appearance of the Black Boosted Gear. Well, based on my research, I successfully found the black boosted gear and here is the picture of it.
Black Boosted Gear (Gauntlet)
(Imagine the gem is color red)
Here is the Balance Breaker form
Here is the Ultimate Balance Breaker
(Imagine that color of the armor is black and the rest is color red)
Here is the Juggernaut Drive
Here is the Juggernaut Overdrive
Here is your chant while activating Juggernaut Drive
I who will awaken, am the supreme heavenly dragon who was betrayed by God, I despise the "infinite" and the "dream", I shall become the supreme black dragon of the dark age and I shall crash everything with my scale of my wrath!, JUGGERNAUT DRIVE!
When you activated your Juggernaut Drive, you can also transform to Juggernaut Overdrive if you have enough battle power and very strong desire to transform to that form.
