Crotus (クロトス Kurotosu, 1, 23) is a flat planet that was conquered by Space Shogunate Jark Matter. It appears highly militaristic despite having a regular civilian populace.
Crotus was one of numerous planets to fall to Jark Matter. The first three Kyurangers, Hammy, Champ and Spada launch a defense against them on the surface. While the Kyurangers were unable to stop the invasion without all nine members assembled, they were able to rescue some of the civilians caught in the crossfire.
As a Jark Matter-occupied planet, Crotus received transmissions from the Earth-based Jark Matter Broadcasting. Comandeering the broadcasting center, Tsurugi Ohtori used the facility to send out a message which introduced himself to Crotus among the rest of space.
