Batman is a Time Lord.This explains his ridiculous number of areas of expertise, his physical superiority (which cannot realistically be explained by "he works out"), his gadgetry, and his intellect. He frequently displays knowledge of meditation techniques similar to those used by The Doctor. He has been active in Gotham since the 1940's, with his regenerations being the reason his personality is so different from era to era. His appearance changes due to artistic reinterpretation are also because of this (though there is little appearance variation compared to the Doctor, it should be pointed out that not all Time Lords' regenerations vary as wildly as the Doctor's). Over the years, he has had the following regenerations:
Calvin is a Time LordCome on, he does travel in time. About his inability to do schoolwork, compare with Susan Foreman in the very first episode of Doctor Who.
Calvin is NOT a Time Lord, but the cardbord box IS a TARDIS.As stated above the cardbord box does do an awful lot of weird stuff. However, if calvin were really a time lord, he would have remembered to turn the safty switch off before trying to profit from it. That, and he would have a Sonic Screwdriver. Ms. Wormwood might be the Time Lord who lost it, but that's just me.
Hobbes is Secretly a Fob Watch.Calvin is a young Time lord who was John Smithed and shipped off to earth in hopes of saving at least one member of the race from the Daleks when the Time War turned sour. His TARDIS quickly became an inconspicuous cardboard box, but the object into which Calvin's time lord memories were locked, randomly chosen and hastily created, did not function without unexpected side affects. With Calvin's Time Lord memories and persona in such an easily manipulated form, a stuffed tiger, it quickly began to function as its own distinct consciousness, calling itself 'Hobbes' in reference to Calvin's true Time Lord title- The Philosopher.
Jason is a Time LordHe was sent to Earth when the Time War turned sour, had his TARDIS taken away, his memories of being a Time Lord wiped and placed into the Fox Family, where a spell was put over to make everyone (inculding Jason) think he'd been there all along. His book smarts come from faint unwiped Time Lord memories where he'd go on trips in his TARDIS to historical events where he'd see them unwrapping before his eyes.
Jason is a regeneration of CalvinFollowing on from the previous WMG, when Calvin is 10 years old, he dies in a sledding accident. His death triggers the release of his Time Lord memories from Hobbes, who returns to being nothing more than a stuffed toy. The memories are returned to Calvin, triggering his first regeneration. He becomes Jason. Due to his new appearance, Calvin decides to leave the family he had settled with. Retrieving his TARDIS, he sets off in search for a new home. However, the TARDIS broke down outside the house of the Fox family. Calvin alters their memories to make them believe that he is the youngest child of the family. He decides to call himself 'Jason' to avoid confusion with his previous form, and decides to settle with them until he can repair the TARDIS, which he still hasn't.
Garfield is a Time Lord, who was permanently placed in the body of a cat as punishment for unrevealed actions on Gallifrey.Well duh! Haven't you read Garfield: His 9 Lives? Over the years, he has had the following incarnations:
The Garbage Man is a Time lordThe Garbage truck is his TARDIS.
Wally is a TimelordHe's a deserter from the Time War, who made a life for himself on Earth. He coped with the death of his people by perfecting not caring into an art form.
The Dog is a canine Time Lord.He refuses to let his name be given for the same reason every other Time Lord does. His TARDIS is his water tank.
Snoopy is a Time LordWe've seen the inside of his doghouse, and it is larger on the inside than it is on the outside, just like a TARDIS. Snoopy's time as a WWI Flying Ace who fought The Red Baron - despite living in modern times - has been well documented. And, depending on how frequently he travels back and forth in time, it's likely that some of his personas (Joe Cool and the like) are other regenerations of his; he keeps coming back to check up on his old companions like The Brown Children, taking care to avoid the Blinovitch Limitation Effect.
Sam and Max are Time Lords, and the De Soto is their TARDIS.The DeSoto appears indestructible, and it takes them across America, to Germany, to the North Pole, and to the moon in seconds. It has been shown to be sentient on a few occasions. It even has a soul.
Superball is a Time Lord and has orchestrated the events of the past two seasons to keep Sam and Max from discovering his planWe know from Chariots of the Dogs that Superball has the ability to time travel but keeps this a secret with his mind-wipe device. Also, the device doesn't seem to work well on Sam and Max, possibly because they're immune to hypnotism. Superball keeps turning up guarding doors.
Deadpool is a former Time Lord who is now human.
Superman is a Time LordAfter he died in the fight with Doomsday, he regenerated into a form almost exactly like his first one. His third regeneration resulted in Superman Blue, and a fourth returned him to the status quo. It's a stretch, but we've got to fit this one in here somehow.
