Made from a tank legends Megatron. I used a soldering gun to heat up the pin holding the tank barrel to the original's head and pulled it out. I drilled a little hole in one of the turret halves/arms so the barrel can be used as a cannon in robot mode. The pin was left in to hold the cannon in place in tank mode. The original head was removed and replaced with a legends Evac head. I even got a third mode of it... didn't say it'd be good though.
