Mothership
Phase 1 During phase 1, the Mothership has 8 unique parts shooting and charging lasers depending on each piece. One of the pieces will have 4 turrets pop out and shoot clutters of ammo at the direction of the player. The 4 blue parts of the ship will each shoot a laser and rotate forcing the player to move along with it. Another part will open up the 3 triangle shaped parts on it. One of the parts will send out a red orb shooting small pink bullets at the player as seen in the Devastator boss. The other two of the opened parts will shoot homing missiles at the player.
Once all the parts are destroyed, 2/4 of the pink pieces will break and the rest will power and light up. The 4 blue pieces will each shoot out a laser, similar to what they did before they powered up, but is now the color orange instead of the previous blue, and will split into two lasers. The remaining two pink pieces will open up entirely and reveal a turret shooting ammos at the direction of the player, with the ammos going at extreme speed. There is also a minimized version of The Ancient at its second phase constantly repairing damaged parts and when is damaged a lot, will also repair itself. If it is killed, the Mothership will generate more from the center.
Phase 2 After all the pieces are destroyed in phase 1, the Mothership will say "Behold my new toys!" and will unleash itself from the pieces by launching them away. It will summon bombs every now and then that home to the player when close enough, and will combine one another for a stronger explosion, but will be slower. The bombs will disappear in a few seconds after appearing. The Mothership will constantly have a shield blocking any incoming damage while active. It has 4 tiny edge pieces that fly around the screen randomly leaving a trial that decreases the player's temperature. The edge pieces will shoot homing, red spear-shaped ammos while rotating around the Mothership. It is possible to destroy the main part before the edges bringing them to the 3rd phase, making it a lot more harder.
Phase 3 After the main part is destroyed, it will send the 2nd phase form away and unleash the core. It will take out 8 orbs that shoot a laser connecting each other and will mover places every few seconds, limiting the amount of space the player has to dodge the ammos. It will still summon bombs and have its shield active constantly, similar to the 2nd phase. Every now and then, it will shoot a huge clutter of ammos lasting for around 7 seconds. The edges from phase 2 will shoot its homing ammos at the player if any remained when going into phase 3. This cycle will continue until the boss is defeated or the player dies.
