The Power Rangers franchise has had a long and extensive history dating back to 1993 and even further if one were to count the original Super Sentai series. In either case, with all of that lore in its history, there is a widely accepted canon that fans and critics agree to.
However, thanks to Boom! Studios continuing the franchise into comic book spinoffs, so much about the original Mighty Morphin' series especially and its characters within the entire franchise have been expanded upon and re-contextualized in ways that only the comic book readers will understand. This is specifically true when it comes to different members of the original MMPR squad.
10 Billy & Skull Used To Be Best Friends
Bulk and Skull spent much of the Mighty Morphin' Power Rangers television series tormenting Billy as their prime bully victim, but in the comics, some extra backstory is offered as to how the trio came together.
In Go Go Power Rangers #4 by Ryan Parrott, Dan Mora, & Raoul Angulo, six years prior to the events of the show, readers are treated to Billy's childhood, where Skull is actually Billy's best friend. The older the two got, the more they drifted apart. And the more Skull got closer to Bulk, the more the duo started bullying Billy, although Skull looks visibly guilty every time.
9 Tommy Wasn't Kimberly's Only Boyfriend
Save for when she "found someone else" during the events of Zeo (which winds up being retconned in the comics), Kimberly was always romantically linked to Tommy Oliver. However, with Go Go Power Rangers taking place before Tommy comes into the picture, fans get to see who she was dating during her earliest days as a Ranger.
Before Tommy, there was Matthew Cook, who unapologetically loved Kimberly, but the more her Ranger duties kept them apart and the more Kimberly and her friends kept Matt in the dark about it all, Matt turned his back on all of them.
8 Rita Repulsa Haunts Tommy Long After He's Freed
In the show, despite Tommy handing the Rangers their backsides for five episodes straight while under Rita's control, the team still accepts him with open arms as a friend. In the comics, it's a little harder for the team to get used to this and Tommy truly has to earn their trust.
This process becomes all the harder for the future leader of the team considering he's still being haunted by Rita, literally and figuratively. Figuratively, he's suffering PTSD from being mind-controlled, and literally, she's haunted him in hallucinations she's summoning from her castle.
7 The Backstories Of Rita's Henchmen Are Revealed
Rita's servants always remain loyal to their ruler without an in-canon reason given as to why. Those reasons are given in the comics. Finster, for example, is revealed to have always been a passionate artist who grew bored of living quietly in a peaceful village, especially when the discovery that he can sculpt monsters inadvertently leads to his wife's death. Rita uses Finster's guilt to manipulate him as her servant.
In issue #6 of Go Go Power Rangers, it's revealed that Squatt was offered to Rita Repulsa as a baby by his parents to spare themselves and their planet. She of course accepted the peace offering, but still killed Squatt's parents.
6 Jason, Trini, & Zack Never Quit Being Rangers
It is commonly known by now that when Jason, Trini, and Zack all left the original series to attend a World Peace Conference in Switzerland, it's because of backstage drama that convinced the actors to exit the show. Without such drama existing in the comics world, the trio continues being Rangers.
Boom! Studios find a way to still include the Peace Conference excuse as a reason for why they leave the Mighty Morphin' team, but in-canon, it turns out to be a cover-up for the trio to venture off into space as full-time Omega Rangers.
5 Trini Briefly Dates Jason
It may be strange for some fans to imagine Trini and Jason in a relationship when they barely speak to each other in the original television show (something that even the comics reference) but in this new re-contextualization offered by Go Go Power Rangers, the two become closer once they start training together as Rangers.
Trini develops a crush on Jason that isn't reciprocated immediately, but as time goes on, they agree to start dating. Granted, the period in which they were dating was extremely brief.
4 Trini Then Starts Dating Zack
Trini and Jason's relationship did not last as long as either may have hoped as they realized quickly how their enemies could use their love for each other as a weakness against them. As such, they agreed to be just friends. Interestingly enough, it is after this period that she starts dating Zack.
It is revealed in Mighty Morphin Power Rangers: Pink by Brendan Fletcher, Kelly Thompson, Tini Howard, Daniele di Nicuolo, & Sarah Stern that Zack and Trini started dating each other after the events of that universe's World Peace Conference summit. It seems as if it was during the Switzerland trip that they grew closer.
3 Why Evil Tommy Calls Himself Lord Drakkon
Even diehard fans who have not read the comics yet probably know by now that Tommy Oliver develops an evil streak he calls Lord Drakkon, but only in the comics is the full context offered behind the name Drakkon.
In an alternative universe where Rita convinces Tommy to still be her Ranger after he's no longer under her control, she tells him a story about when she helped an alien named Drakkon protect his planet and bring it to a state of peace. Hoping to use evil to protect the world himself, a misguided Tommy rechristens himself as Lord Drakkon.
2 Zordon Recruits Bulk & Skull As Rangers
Each of the Mighty Morphin' Power Rangers comics ends with a mini-story that exists outside of the main story, often starring Bulk and Skull. In one of these stories, Issue #0 to be exact, the two wannabe heroes finally have their dreams of becoming Power Rangers, courtesy of Zordon himself.
When the Rangers become trapped inside of a monster, Zordon reluctantly recruits Bulk and Skull with rare Power Coins to save them, dubbing the duo the Purple and Orange Ranger, respectively. When the mission is over, Zordon has their memories of the adventure wiped.
1 The Mighty Morphin' Rangers Weren't The First Ranger Team With A Female Leader
Since Mighty Morphin' Power Rangers was the first series in the franchise to ever air, it is commonly accepted canon that they were also the first Rangers in existence. In the comics, it's revealed that this is not the case, nor were they even the first team assembled by Zordon.
A flashback to 1969 reveals that a Psycho Ranger traveled to the moon to try and retrieve Rita Repulsa from her prison. To prevent this, Zordon assembled his first teenagers with attitude, led by Grace Sterling. The mission was a success, but not without three members killed. Grace and the Yellow Ranger, Terona, both had their power coins retrieved from them by Zordon, but in hopes of making a difference in the world with their new knowledge of enemy aliens, they founded a company called Promethea to prevent similar disasters against the earth.
