Diaclone Land Battle Cruiser with two raid chambers
For anyone considering it, it is never too late to get into the new Diaclone reboot line. This is the add on set for Big Powered GV that works as a toy of its own. I would recommend either Big Powered or a Diabattles for starters (either the 2.0 or the cosmo maneuvers type). I can't speak highly enough about this line. I think its versatility can make it confusing to see online. There are so many configurations.
