Combined Combatant

The Combined Combatant appeared in 2011 movie called Kaizoku Sentai Gokaiger the Movie: The Flying Ghost Ship. Los Dark commands foot soldiers that the past 34 Super Sentai battled, reduced to wandering souls. They see themselves as brave selfless warriors for evil. They reside within the dimension of the dead, whose portal is in the Ghost Ship. They have the ability to form the Combined Combatant (合体戦闘員 Gattai Sentōin), which can speak in roars as usual.

The Combined Combatant was formed via the Nanashi using it's power to combine all of the other footsoldiers together into a single being which was able to stand up to the Gokaiger.

But when that Nanashi prepared to deliver the finishing blow, the other footsoldiers began to rebel wanting to deliver the blow themselves, with various footsoldiers merely fighting among themselves. The fighting was seen by the Gokaigers (mainly Luka) as if it was dancing, inspiring them to use the Battle Fever J keys and destroy the Combined Combatant with the Penta Force cannon.
