Chase (チェイス Cheisu?) is one of the main characters in the series, Kamen Rider Drive. For a short time, Chase was the original Kamen Rider of the series, Kamen Rider Proto-Drive (仮面ライダープロトドライブ Kamen Raidā Puroto Doraibu?) as called by Krim Steinbelt himself prior to the event that would later be known as the Global Freeze. At this point in time, Drive was not fully operational and completely rendered Chase to only being capable of destroying a Roidmude's body rather than destroying them entirely. Sometime during the Global Freeze, Chase was incapacitated by Heart and was robbed of his memories.
