Rexion Core

Rexion Core (レクシオンコア Rekushion Koa^?) is the first boss of Stage 8 in Gradius Galaxies.

Attack patterns[]

This battle has three phases:

Its first attack pattern will consist in shooting two lasers, one after the other, that home in on the player by altering their course. It will have two assisting quad-laser that widen their laser firing gap.
After defeating it, the ship gets resurrected by what appears to be a backup repair module. After getting repaired, it shoots bubbles that pop and release shots omni-directionally, like a grapeshot. Its two assistants will be mace-shaped laser weapons that first fire straight, but then create a perimeter around the player, firing lasers at the near edge in a wide arc. To prevent getting hit, the player must stay on the far lest side of the screen and stay vertically centered.
After defeating it for the second time, the machine resurrects the core again and it will keep firing the same buckshot, except its assistants will now be two spherical enemy generators that summon Zubs to ram the player.

After defeating it for the third time, it dies and finally explodes.

The battle against Rexion Core with three phases is based on the battle against Vasteel Original and Vasteel Nocht from Thunder Force V & VI, respectively.
