|This character exists primarily or exclusively within the Pre-Super Genesis Wave continuity.|
Information in this article may not be canonical to the storyline of the games or any other Sonic continuity.
Serving as the Floating Island counterpart to Rotor, Cobar was one of those who determined that due to disruptions of time, Mobius was going to explode. Cobar was also able to hack into the Brotherhood's spy satellite network, by accident. He proposed sending King Sonic back in time to fix things, but Sonic vanished when the time machine malfunctioned.
Cobar has not appeared in the alternate future but Shadow does mention him. It is suggested that Shadow may have killed him as he was the only other person besides Rotor who worked on trying to save the future. He retained his memories of the original future as he was near Robotnik's Tachyon Displacement Chamber when Sonic went back in time.
