This is the HG 1/144 Try Burning Gundam Bandai model kit. :) Try Burning Gundam makes it's debut early in Gundam Build Fighters Try. It's built on the same foundation as the Build Burning Gundam, originally built by Sei Iori. Sekai Kamiki discovers the Build Burning Gundam hidden inside of a trophy on display in the Gunpla Battle Club room on his first day while choosing a Gunpla to use for his first time playing Gunpla Battle. As Sekai learns more about Gunpla Battle, he bonds with Build Burning Gundam in a way that allows him to tap into it's true power, as well as power beyond that. The Build Burning Gundam's frame couldn't take the strain that this power put on it though, and ultimately had to be modified with a specially created system to be able to handle the power. With these modifications, it became known as the Try Burning Gundam.
The Try Burning Gundam is not armed with any weapons. The Try Burning Gundam is a close combat type Gunpla built for hand to hand and up close combat. This plays to Sekai's strength as a martial artist. Utilizing the Jigen Haoh martial arts style, Try Burning Gundam can use all of the martial arts that Sekai can, and even some that he can't. ;)

I'll be honest with you guys, I am loving this kit! :) Bandai did an absolutely fantastic job of bringing the Try Burning Gundam from the anime and making it into a real model. :) The assembly isn't too difficult, but swapping out all of the clear blue parts to attach the flame effect pieces takes a while. They're made to pop on and off easily though, so swapping them out isn't difficult, it takes a few minutes. This kit also comes with several different sets of hands for different martial arts styles and poses, so you get this model ito all kids of cool poses. :) This kit usually retails online for $15 to $20, so for such a low price, this is a fantastic kit! I highly recommend this one to anyone. :)
