Personality
Ashton Seymour is a mysterious young man who is portrayed as being cheerful to the extent of being annoying to those around him, but becomes serious in battle & sees material objects as more important than anything else. Oliver, aware that Ashton is Past Caller, avoids getting in his way. He also appears to know about Darren's past, referring to sea cucumbers as being something Darren had always wanted to taste. He travels from A.R. World to A.R. World, stealing what he refers to as "treasures".

It is revealed that he comes from an A.R. World (referred to as the "World of Past Caller") where he was an officer who served the evil Fourteen who has deemed Kamen Riders as threats to the public peace. Ashton hunted them down & turned them in for education until he captured the leader of the Kamen Riders: Kamen Rider A-King. When A-King is unmasked, he is revealed to be Ashton's older brother Derek.
