Scooby-Doo Timeline

* 23 August After years stalling, the Hex Girls release their ill-fated, newly styled album

* Northern California small town Doctor Dan Challis races to stop the spread of a terrible fate for all children in the region who wear masks produced by the local Silver Shamrock company.

#### 2011

* Starting by unmasking the Black Knight in their home town of Coolville, Ohio, the Mystery Inc. gang begin their road trip across the country solving mysteries.

* Batman pursues Killer Croc across the country to Texas, where the Sawyer family takes the injured villain in. There, Batman must contend with not only Killer Croc, but Leatherface as well. When he finds out that the Sawyers gave been kept from custody for protecting an ARGUS secret, Batman hurts the family so badly they won't be able to hurt anyone again.

* Continuing their cross country trek westbound, Mystery Inc find themselves down a lonely road in Texas. Stopping for directions at a gas station, they end up in the Sawyer residence. There, they are terrorized by the babbling bad guy Leatherface, who presents more danger than they've ever faced before. Due to an injury Leatherface previously sustained, they narrowly escape in one piece.

* Having escaped the wrath of Leatherface in tact, a battered Mystery Inc continues their journey, heading home through Illinois. Running low on gas, they stop into the town of Haddonfield. With the town empty, they encounter Michael Myers and try to fend him off until Batman reaches them.

* After near-deadly encounters with Jed "Leatherface" Sawyer and Michael Myers, Batman teams up with Mystery inc. to track down to other boogey men, Jason Voorhees and Freddy Krueger. Freddy unites the four slashers and it takes a dream world war to bring them to justice.

#### 2012

* As Robin grows older, he spends more time fighting by the side of the Teen Titans than obeying Batman's orders and a rift begins to form. Though not left on a negative note, Dick moves to join the team in San Francisco.

* Damian al Ghūl born.

* Helena Bertinelli's parents are killed in a mob attack. She and her bodyguard-turned-guardian Sal work out a plan for revenge.

#### 2013

* After trying to steal tires from the Batmobile, Jason Todd is discovered by Batman, and, after proving his mettle, joins his side as Batman's new sidekick, taking Dick Grayson's still-in-use code name.
* 26 March The Hex Girls officially disband, having been on hiatus immediately since the release of their 2010 album.

* A new vigilante, the Huntress, attacks the remaining pockets of Gotham's mob, with her crude means being balanced by her willingness to take life. Revealed to be fifteen year old mob orphan Helena Bertinelli, she and Jason Todd become involved on and off to Batman's disapproval.

* After the two Robins inadvertently find themselves side by side, the wedge between Bruce and Dick is solidified by Dick's feeling that he has been replaced and he is fired from the Robin identity-- but not before he can quit.

#### 2014

* A new cult forms in Gotham, led by the eloquent but enigmatic Deacon Blackfire. Leading an army of the homeless, Blackfire had an increasing foothold in Gotham's slums. Blackfire's forces pin Batman down, and it's up to Jason to use the batmotank to save him from the maze-like sewer lair.

* Joker paralyzes Barbara Gordon from the waist down and "kills Jason Todd" in his most personally atrocious attack on the Batman in an attempt to prove that he can make Commissioner Gordon and Batman as bad as he is in one day.

#### 2015

* Batman fights with Dracula in Gotham, leading to what would be in this year a rare interaction with Superman to fight a new batch vampires and werewolves, in part possible from the Romulus Strain.

#### 2016

* Tim Drake becomes Robin after deducing Batman's secret identity and convincing Dick, Alfred, and ultimately Bruce that Robin needs a Batman.
* In an attempt to gain noteriety, Arthur Brown brands himself the supervillain Cluemaster.
* Batman and Robin take on the political youth war between Anarky and The General, with both parties using social media platforms and extremist mainstream candidates to rally their bases.
* After the big four, the gang separate for a little while. The ensuing adventures for Shaggy and Scooby include Boo Brothers, Ghoul School, The Reluctant Werewolf and maybe the 13 Ghosts. Velma completes some degrees (as the timeline reaches into the Tim Drake era) Fred runs a fairly successful pseudo journalistic blog, and Daphne rejoins Scooby and Shaggy. It's only a matter of time before the Gang is rejoined by a more mysterious than average mystery. The mystery brings them together with Batman and various other detective heroes, and was orchestrated by none other than a very real and still living Sherlock Holmes. Wishing to pass on his knowledge, Holmes drafts the heroes into what he has dubbed the Detective Collective. From there, Batman suggests they should meet Swamp-Thing if they have an interest in exploring the truly supernatural. Shaggy puts his old shirt, pants and shoes back on, which are quite literally the same outfit, having been worn every day. Down in the Louisiana bayou, they encounter Victor Crowley and successfully fend him off until Swamp-Thing appears, and they team up. Swamp-Thing introduces them to the Justice League Dark, comprising Constantine, Etrigan, Zatanna, Deadman, Adam Frankenstein, Madame Xanadu, and Swamp-Thing himself. They solve some mystery at the heart of Coolville which is the source of Scooby-Doo's speech.
* Jon Kent born.

#### 2019

* 25 Feb The Hex Girls reunite successfully with a well-regarded new album.
