The ones off of ToysNJoys are in English. The box on the outside is in Japanese but when the letters and words come up on inside they are in English. And if you stick to metal it will come up with like Mettaurs andSometimes even FireMan and stuff. Also, you can get more than just MegaMan on them. If you reset the PET you can get a different Navi out of Roll and ProtoMan and GutsMan (I think). They are like the Digimon toys... if ya reset you get a new one!
But as of yet there are no \"official\" english ones, just ones that were Japanese and then edited off of ToysNJoys or somewhere else where you can get them. So technically you can \"Jack in\" but only if you stick the cord on metal!
