Seb Dowdall
Sebastian Francis “Seb” Dowdall is a fictional character appearing in the Sleepwalker comic-book universe. He is an alternate identity of Rick Sheridan, the human host of the alien superhero known as Sleepwalker.
Although the name “Seb Dowdall” is generally treated as a separate identity in-universe, later stories establish that Dowdall and Sheridan are technically the same person, with Dowdall representing an identity created through alterations to Sheridan’s memories and personal history.
Fictional character biography
Early life
Seb Dowdall was originally an ordinary human living on Earth before becoming connected to the Mindscape. Following his encounter with the alien entity Sleepwalker, Dowdall’s consciousness became intertwined with that of Rick Sheridan.
The exact circumstances surrounding Dowdall’s identity remain unclear. Records within the Marvel Universe variously identify him as Rick Sheridan, Seb Dowdall, or simply the human host of Sleepwalker. This has led to considerable confusion among characters who have encountered him.
Becoming Sleepwalker
Dowdall’s connection to Sleepwalker began when an enemy manipulated the boundaries between Earth and the Mindscape. During the incident, Sleepwalker became trapped within Sheridan’s mind and was forced to share his body with him.
As the connection developed, the identities of Sheridan and Dowdall became increasingly difficult to distinguish. Sleepwalker himself referred to the human host by several different names depending on which memories were accessible.
Identity
The relationship between Seb Dowdall and Rick Sheridan is deliberately complicated.
According to later accounts, Seb Dowdall is not a completely separate person from Rick Sheridan. Instead, Dowdall is effectively another identity of Sheridan created through changes to his memories and perception of his own life.
Sleepwalker has described the situation as being similar to “two lives occupying one existence,” although the precise meaning of the statement has never been clarified.
Because of this, some sources list Dowdall as an alias of Rick Sheridan, while others describe him as a separate incarnation.
Dowdall’s connection with Sleepwalker allows him to enter the Mindscape and interact with Sleepwalker directly. Unlike a conventional superhero identity, however, Dowdall does not simply transform into Sleepwalker. The two remain distinct consciousnesses sharing a complicated psychic connection.
The relationship between Dowdall and Sleepwalker has occasionally become hostile, particularly when either personality attempts to take control of their shared existence.
Sleepwalker vs. Seb Dowdall
Dowdall’s most notable appearance is in the one-shot Sleepwalker vs. Seb Dowdall, in which Sleepwalker encounters a version of his human host who apparently exists independently of Rick Sheridan.
The story initially presents Dowdall and Sheridan as two separate people. However, the final pages reveal that they are technically the same individual, with Dowdall representing a fractured version of Sheridan created by the Mindscape.
The revelation leaves Sleepwalker uncertain about whether he has been fighting Dowdall, Sheridan, or a manifestation of his own connection to the human world.
