The Electronic Cage is the sub boss of the last stage in Gradius.


The Electronic Cage first appears in Gradius. It looks like two bars, which fire electricity between each other. The Cage doesn't appears in the NES version of the game.

A parody version was later featured in Parodius Da!, and it was later upgraded into Electronic Cage MK2 in Gradius ReBirth. The Electronic Cages, as well as their upgraded/parodied versions, are generally found just before the final bosses.

Attack patterns

The Electronic Cage doesn't have much of a pattern. It can't be destroyed, It flies in, generates four streams of electricity between the bars, and then stays there for a while and leave. The only real danger are the Duckers, not the cage itself. The cage is easily avoided if you don't fly into the middle of it.
