Mad Nautilus

## Description

One of the bosses encountered in Rockman X Command Mission, a turn-based role-playing game. This huge shell-type robot created by Dr. Psyche, the crazy scientist, is equipped with guided missiles as well as four tendrils shooting rays inflicting various afflictions.

## Appearance

Story Mode: Military Train 8-6

Challenge Mode: 13th Boss node (Level 75 Required); Jakob Orbital Elevator Floor 35

## Moves

**Mad Ecstasy**: Mad Nautilus launches four homing missiles to the player in successions

**Mad Blaster**: Mad Nautilus sends a barrage of thin white lasers. Does minimal damage and easily negated by the invincibility frame of the player for standard enemy hit

**Mad Cocktail**: Mad Nautilus's most dangerous attack, aiming the four tendrils in various directions. The player will see yellow warning lines, which dictate the path of the lasers. This gives the player around two to three seconds, on where to hide or stay put for avoiding the trajectory of lasers. While the Yellow beam does not inflict any status effect, each beam applies damage and a certain status effect: Blue beam inflicts Chilled effect, Green beam inflicts Poisoning effect, and Pink beam inflicts weaken DEF effect.

**Open/Close Bulkhead**: Mad Nautilus will open its spot that can receive damage after performing Mad Cocktail. The bulkhead is the upper portion of the boss that looks like a red cap with four green-circle glass-like objects, each having a purple outline. When the bulkhead is open, you can see a large green portion that looks like a core. Take caution, the bulkhead also closes after performing another Mad Cocktail.

## Strategy

Once the battle starts, do not shoot your weapons or use your dive triggers yet. The boss is initially invincible to any damage. You have to wait for Mad Nautilus to perform Mad Cocktail and Open Bulkhead. While waiting, what can be done is to avoid the attacks from Mad Blaster and Mad Ecstasy.

Mad Ecstasy can be avoided by double jumping over the first/third missiles and falling down so the second/fourth missiles miss. Preferably, stand on the high ledge of the arena, and time your jumps.

Mad Blaster could be hard to avoid because of the sudden burst, but you can double jump to avoid the remaining barrages. If the player has high total power, the invincibility frame can negate the damage from the remaining barrages.

Depending on the path of the yellow warning lines of Mad Cocktail, the player can avoid the hit of the lasers by choosing to crouch or hide in the pit fall gap by wall jumping.

Once Mad Nautilus performs his first Mad Cocktail, you will notice the red cap open, which is the Open Bulkhead. You can now shoot with your buster or machine gun weapons, aim in proper range the Dive Triggers equipped.

Also, It might look tempting to, but do not stay below Mad Nautilus. The tendrils can inflict damage upon contact.

## Trivia

* The original boss fight in Rockman X Command Mission is a turn-based, role-playing game. So this boss battle in Rockman X Dive is a novelty for the majority of Rockman X game players.
* Strangely, Dr Psyche's head is depicted as being holographic, even while attached to the solid Mad Nautilus body.
