Maelstrom

Maelstrom are megazord-sized grunts of the Southern Cross Army.

They first appeared after the defeats of Guardian Manta and Guardian Mamba.

Another appeared alongside Dragstar in Block 14.

Three fought Jet Gattai Ka-Oh Biker in Block 20 (instead of Bayern Curve).

Two more fought Kujira Gattai Kingda Ka in Hakugei's debut.

On two occasions during the Seven Spears arc were monsters joined by Maelstrom (Flevo and Dunklen).

They also appeared during the team-up with the Kamen Riders and Kagarangers.

They also appeared alongside Thunderbird's robo fight.
