Think the Stink

Think the Sink was an inmate in Prison Galaxy that Run the Hedgehog teamed up with in order to escape. He sacrificed his life in order to get Super Sonic Level 4 to split the merged chaos emeralds into seven pieces so Run could use them for his battle.

History
Think's history before Prison Galaxy is unknown. After being an inmate for some time, he discovered the mysterious properties of Chaos Emeralds, finding out they are in fact unbreakable. Using this knowledge, he and the other inmates somehow split the emeralds they found into shards and augmented their weapons with them, using them to fight against the guards. Unfortunately, this escape attempt failed and Think remained in prison. This allowed Prisonic the Hedgehog to learn of Think's discovery and use emerald shards to coat the walls of the prison, making it indestructible.

Powers
Think's most useful ability is his intelligence. He is, according to Valentine the Mink, the smartest person in all of Prison Galaxy. Otherwise, he doesn't seem to possess any extra level of strength or powers. Like most characters, he is able to travel through space by flying, and at faster than light speeds as he traveled to the center of Prison Galaxy in mere moments.
