Grand Crawler is the boss of the training course, and the true first boss in Raiden DX.
Despite apparently being just a regular tank, the Grand Crawler puts up a good challenge. It is equipped with a double-barreled cannon and guns all over it's body. The boss can also open and close two side wings which have even more weapons on them, raising it's firepower considerably. The side wings can be destroyed, however.
- The Grand Crawler is a modified Land Crown, however although it has wings it lacks the spinning mobile drone units in it. It's controlled by a Red Crystal.
