Dangerous Seed/Stage 7-U

If the sixth boss, whether Shark-Mouth or Monster-Head, was successfully destroyed, the seventh stage takes place in Uranus's orbit. However, two alternate stages are possible if the sixth boss escaped, depending on that boss's identity. If Shark-Mouth escaped, Stage 7 is Pluto's orbit, with Monster-Mouth as the boss. If Monster-Head escaped, Stage 7 is Neptune's orbit, with Ultimate-Tiger as the boss.

Boss
Uranus: Twin-Claw (ツインクロー) An enormous twin-clawed creature who fires death rays from the centre of his body and boomerang maggots from his claws. The maggots can be destroyed.

Pluto: Monster-Mouth (モンスターマウス) A fusion of Shark-Mouth and Twin-Claw. Uses Twin-Claw's tail beams and all of Shark-Mouth's attacks.

Neptune: Ultimate-Tiger (ウルティメイトタイガー) A fusion of Monster-Head and Twin-Claw--in other words, a fusion of all three of Multi-Squid, Shark-Mouth, and Twin-Claw. Attacks like Monster-Mouth, but replaces the bubbles with Multi-Squid's centipedes. The same problem potential with Multi-Squid and Monster-Head applies.
