The WFC-S6 Autobot Battle Patrol figures Autobot Topshot and Flak convert in 7 and 4 easy steps from robot mode to tank modes. Their tank modes combine to form the Electroverge Neuro Blaster weapon accessory. Use the weapon mode to equip other Siege figures with larger mission loadouts and use Fire Blasts (not included, sold separately with Battle Masters figures) to simulate blasterfire or explosions firing from the end of the Electroverge Neuro Blaster weapon mode.
