Its Engineer Kipo's Japanese name. For whatever reason, some names got changed or rearranged with translated to the English game.

(技師ピーポ) means "Gishi Pipo" or, of course, "Engineer Kipo". They just never did the same name change on Mega Detonator.

I wouldn't be surprised if some creatures in Kaijudo like the "Blastforge Captain" mentioned on a few cards never show up either.
