- "Leave me be before I claw you offline!"
The condor Casettibot.
A silent condor, Blockrock was the last Cassettibot constructed, and is the best friends with Ramhorn. Blockrock feels sad and lonely even among the rest of Cassettibots. This may be due to his age. Even Ravage stays away from him. Rival to Ratbat.
- Tom Kenny voiced Blockrock.
