Ripper Roo

Ripper Roo (also known as Doctor Roo) is an insane blue mutated kangaroo. He is widely considered to be Dr. Cortex's first and failed experiment with the Evolvo Ray, which is debatable seeing as how he managed to complete university-level education as of Crash Bandicoot 2: Cortex Strikes Back. He frequently uses explosive crates when battling Crash. This can be seen in Crash Bandicoot 2: Cortex Strikes Back, where he lays down TNT squares and nitro squares with his cane, in Crash Team Racing where he drops TNT Crates, and in his appearance in Crash Bash where he will lay down TNT squares on random tiles. He also has razor sharp claws on his toes that are his main method of attack.
