Dave (The Train in Vain and the Junkmail Messiah)

Dave was a grey-skinned humanoid and a friend of Theo Possible.

Biography
After Theo Possible boarded a train on the Parallel Line, he met with Dave, a friend of his. On the train, through a line of questions from Theo, he explained that he was "no stranger" to the Parallel Line, and that his ship belonged to another as they had struck a bargain; despite the fact that Dave, in Theo's words, "loved that ship!", he had to part ways with it as he was going through rough times.

Dave's ride on the train was taken with the intent of a visitation at Carthage, which Theo thought was "nice", depending on the period. Theo then recommended him a "great bar" by the harbour, although Dave claimed there would be no opportunity for him to visit said pub. Theo then proceeded to ask him what period he was planning to visit before they were cut off by Blakey, a robot demanding them both to present their tickets.

After Theo presented his ticket, Blakey proceeded to request a ticket from Dave, leading him to call Blakey a "Supercilious automaton" and describing his history, explaining that he had been a voyager between realities since before the Parallel Line - or indeed, Blakey - were first conceived, before aggressively asking "...and you ask me if I have paid my fare?". This proved ineffective in swaying Blakey, who continued to tell him that he needed to have a valid ticket to travel on the Parallel Line, and kicked Dave off of the train, despite Theo's vouching for his friend.

Dave was kicked off of the train in Doomwitch Void, which frustrated Theo, although Dave told him not to trouble himself. He then requested Theo to call Demeanor Demise, the new owner of his ship. After Dave was kicked off, Theo texted Demise to help Dave. (COMIC: The Train in Vain and the Junkmail Messiah)
