The names Rollbar and Greenjeeper were listed by some initial sources because this toy was a homage too the 2000 Car Robots toy, who was called Greenjeeper by Hasbro fans... that was the same mould as the Hasbro RID Rollbar toy. The actual English name on the packaging is Gregevor, which I think is meant to be pronounced Gre-jee-ver, to be similar to the Greenjeeper from the 2000 Car Robots line, as the Japanese printed name is identical to the Car Robots toy packaging. (so maybe that 2000 Car Robots toy was supposed to be pronounced like Gregevor, instead of Greenjeeper... but us English-speeking fans just picked an English name that makes more sense - like people calling the Gen1 Dezarus toy as Deathsaurus.
