Master Core: ABIS (マスターコア: ABIS Masutā Koa: ABIS?) is the transformation of SCR-HD, created when SCR-HD merged with Astral Babylon's artificial black hole/core unit and the energies from the five Arks of the Cosmos. It is the final (and only) boss of Sonic Riders: Zero Gravity.

After SCR-HD completed its objective by bringing the Arks of the Cosmos to Babylon Garden, it became Master Core: ABIS, only to be defeated by Team Sonic and the Babylon Rogues when they tried to stop the ship's core unit from creating a black hole that could destroy the Earth.

History

Near the end of Sonic Riders: Zero Gravity, SCR-HD appeared at Crimson Tower and stole all five Arks of the Cosmos from Wave. Still acting according to the objective given from the Arks of the Cosmos, SCR-HD brought all the Arks of the Cosmos back to Babylon Garden. This transformed Babylon Garden into Astral Babylon and made the core unit of Babylon Garden create a black hole that threatens to consume the planet. In the process, through the Arks of the Cosmos' influence and power, SCH-HD merged with the core unit and transformed into the twisted Master Core: ABIS.

Soon after transforming, Master Core: ABIS was confronted by Sonic, Jet and their respective teams on the Mobius Strip, who had come to disconnect the core unit and stop the black hole from destroying the world. Master Core: ABIS fought back however, and tried to use the Arks of the Cosmos' gravity manipulating abilities against them. Sonic and his allies, however, used this power against Master Core: ABIS and managed to defeat it. This resulted in Master Core: ABIS being consumed by the black hole it had created, thus disappearing into nothingness.

Powers and abilities

With the five Arks of the Cosmos and the core unit of Babylon Garden, Master Core: ABIS is granted powers and abilities far beyond its normal form. Having the Babylonians' gravity technology at its disposal, Master Core: ABIS can manipulate gravity to perform Gravity Dive on a larger scale than any other user. It can also completely distort gravity over an immense radius, resulting in the environment being torn apart by gravity shifts.

Master Core: ABIS can form large yellow energy bolts which it can shoot them at its opponents. It can also create and gather giant blocks of molten rock and throw them like meteors at its opponents, creating large explosions upon impact. It also has the ability to teleport over short distances.

Battle

Master Core: ABIS will be hovering along the track while staying in front of the leading racer. He will attempt to hit the racers by either of the following attacks, one of which is used per lap:

  • Master Core: ABIS charges a brief moment before shooting large energy bolts along the track twice in two sections of the track per lap, damaging all riders on its path. He will adjust his position along the width of the track to get a better aim at the leading racer. When playing in Story and Time Attack modes, the attack is used in the second lap. When playing just two laps in Free Race mode, this attack is used on the first lap.
  • Master Core: ABIS raises its arms while the camera points slightly upward to reveal several meteors suspended in the air. After a short while, he will drop his arms while the meteors crash onto the track and explode. Getting hit by the meteor will cause the player to take damage. He will do this twice in two sections of the track per lap.

Riders riding on Bike and Wheel type Extreme Gears can knock back against either of those attacks for Gravity Points.

The attack behavior which Master Core: ABIS uses in the current lap depends on the number of laps of the course the player has set in Free Race mode (Story and Time Attack modes follow the same behavior for the default three laps in Free Race mode):

  • 1 lap: Meteor only.
  • 2 laps: Energy bolt in Lap 1, meteor in Lap 2.
  • Odd number of laps from 3-99 inclusive: No attack in Lap 1, energy bolt in all even laps starting with Lap 2, meteor in all odd laps starting with Lap 3.
  • Even number of laps from 4-98 inclusive: No attack in in Lap 1, energy bolt in Lap 2 and all odd laps starting with Lap 5, meteor in Lap 3 and all even laps starting with Lap 4.

Hence in all lap number settings, Master Core will always use the meteor attack in the final lap of the course.

Between each wave of one of the aforementioned attacks, Master Core quickly moves ahead of the track and distorts the gravity such that it causes all racers to automatically use Gravity Dive. Using the lifted crystal-like floor tiles, the player must use Meteor Burst to hit the Master Core: ABIS before their GP Gauge depletes. After hitting it, Master Core will be pushed back and will restore gravity back to normal. The player needs to hit the Master Core twice for a lap to be completed. If the player's GP Gauge is depleted, the player will helplessly float in mid-air along the course until Master Core: ABIS restores gravity back to normal. If a computer-controlled character reaches Master Core: ABIS before the player, he will teleport away without taking damage (and will not count as a completed lap) and deactivate Gravity Dive. If any racers are falling into a pit after flying past a ramp when gravity returns to normal, they will be pushed pack up into the air to land safely at the track on the other side.

The key is to always stay in front of the computer opponents while having enough Gravity Points in the GP Gauge for the Gravity Dives to end the boss fight and race. In Story Mode, the player must complete three laps (hit Master Core: ABIS six times) in the course as Sonic within five minutes.

Trivia

  • Master Core: ABIS' name is derived from its symbiotic relation to the black hole's core and the word "abyss", a common term for a seemingly-endless stretch of empty space.
