The Bobby Fulbright we meet in
the game isn't the real Bobby Fulbright. The real Bobby
was murdered a year before the start of the game.
Bobby is actually the Phantom, an international spy and
assassin who sells his skills to the highest bidder. He is
a master of disguise that can appear as and imitate just
about anyone (often after killing the person he means to
impersonate). No one knows anything about him; having
lived in disguise for so long, even he is unsure of who he
used to be or what his real personality once was.
Seven years ago, Phantom was hired to steal a valuable
moon rock sample from GYAXA, and sabotage any further
progress. To that end he donned a mask and stole Metis's
uniform jacket, which allowed him to pass for Metis in the
eyes of robot Clonco and Ponco. While stealing the sample,
he was found by Metis herself, and he was forced to kill
her. Immediately afterwards, Athena arrived, and in a
panic she stabbed the Phantom, spilling his blood on the
moon rock. Forced to abandon his mission for the time
being, he stashed the moon rock in a sample capsule and
retreated. The capsule was then taken to the rocket that
was to be launched. Phantom tried to sabotage the launch
with explosives, but Hoshinari was able to pull it off
anyway and launched the space probe Future. There was
nothing more that Phantom could do, so he disappeared.
Six years later, Phantom killed and assumed the identity
of police detective Bobby Fulbright. What his exact
intentions were at the time is unclear, but it put him in
a good position when, a year later, Future returned from
deep space. Assuming that the capsule still held the
bloody moon rock, Phantom felt he had no choice but to try
and steal it. He threatened the center with another
bombing, which Oogawara took seriously and tried to
prepare for, but to no avail. Posing as police security
responding to a terrorist threat, Phantom bombed the
center, and killed Daichi in the process of trying to
steal the capsule. Though Oogawara and Detective Arme
prevented him, he escaped and continued to plant and
destroy evidence to cover his tracks and place the blame
on Athena.
Once Bobby reveals himself as Phantom in court, he cycles
through several disguises, changing his personality to
match. He also has an assortment of spy gadgets he uses to
try and escape the courthouse and thwart Phoenix and Co.'s
attempts at cross examining him, including jamming
equipment and a hookshot.
