Voltron Knockoff?

Hi,
This is my first time on here. I was curious if anyone had info on this figure. I thought it might be Voltron related, but I was on a Voltron site and they said it wasn't. It has been in my parent's attic for about 25-30 yrs. The manufacturer is Y & K, Made in Japan. It is about 2 ft. tall, the right hand is spring loaded and shoots out when you press the button. Also had two small rockets ( 1 on each leg), I lost the rockets when I was a little kid. Any info would be greatly appreciated. I'm going to sell it on ebay. I put two pictures in my gallery. Hope that works.
Thanks
