Alpha Base Robot is a Korean version of the Transformer Overlord, from the Transformers: Masterforce series. It's substantially different from the original. Some of the obvious changes include a completely different head, color scheme, and different shoulders.

The head and shoulders are actually stolen from Star Saber, from Transformers: Victory .

Like the original, Alpha Base Robot can transform from a jet and tank, to a robot mode, and then to a base mode. Two small Powermaster figures activate features, such as spring loaded guns and trap doors. There's a gun that fires missiles, claw arms, gun turrets, secret compartments and more.

This is a bootleg of amazing quality. If I didn't know it was made by Academy, i'd swear it was Takara. Everything goes together tightly, and transforms properly.

Alpha Base Robot comes in a HUGE Box, measuring 30" x 20" x 5". It comes with a sticker sheet, full color instructions, and a baggie of accessories.

This is a pretty rare toy. I've never seen another one like it. A suitable replacement if you can't find the original version of overlord.
