Power Rangers is the name of the franchise spanning nearly two decades that adapted the Japanese tokusatsu Super Sentai series for Western viewers. Debuting on Fox Kids, and produced by Saban Entertainment (with the original Sentai shows produced by Toei and Bandai), the show centers around a team of teenagers / young adults, armed with sophisticated weaponry and gadgets, giant machines that combine into even bigger machines, and wear brightly-colored spandex while fighting aliens and monsters. It was a smash hit when it first aired in the early 1990's, and while most of the children who enjoyed the original series have long since grown up, new seasons continue to be produced by Hasbro (who bought Bagan Brands, who bought the rights from Disney, who bought the original Saban Entertainment).
And just like everything else, Chris got his grubby little hands on them.
Power Rangers and Chris
Not much is known about how much Chris enjoyed the Power Rangers franchise, though it is known that Chris prefers the original Mighty Morphin Power Rangers over the newer series...
Chris is likely either unaware that Thuy Trang, the actress who played Trini, the first Yellow Ranger, died tragically in 2001; that, or he is simply in denial about it. Either way, it renders such a reunion a complete impossibility. Not helping matters, David Yost (who played Billy, the Blue Ranger) regrets ever being in the series in the first place, he claims he was harassed over his sexuality. As for the rest of the actors, a number of them have moved on to bigger things, including Amy Jo Johnson (who portrayed Kimberly, the first Pink Ranger), becoming a major television actress, Jason David Frank (who portrayed Tommy Oliver, the Green/White Ranger) joining the Mixed Martial Arts circuit, and Johnny Yong Bosch (who portrayed Adam Park, the Black Ranger) becoming a well-known anime voice actor, voicing famous characters such as Trigun's Vash the Stampede, Akira's Kaneda and Code Geass's Lelouch.
On The Wall of Originals, two hand-made Trainer cards are devoted to the series. The first is a card devoted to Bulk and Skull, the two dimwitted bullies from the original series who served as effective comic relief. The second is a Sonichu Zord, predating the existence of Son-Chu by at least nine years. It seems that Chris attempted to make this Sonichu Zord like the popular Tigerzord, but it comes off hideously. Chris depicts Sonichu's head on its chest, with a dull gray robot head popping up in the first head's place, and its tail being used as a sword. Needless to say, it fails horribly.
Power Rangers in Sonichu
In the CWCipedia's article on the Private Villa of Corrupted Citizens, it is mentioned that Chris was once a member of a Power Rangers team, despite the fact that all the other teams have been from California or outer space. In fact, he was the team's leader!
It doesn't mention who he fought or what he fought or even what powers he used, but it is said he piloted a go-kart(?) that was "sleek like an Arwing" and was the head of the so-called Kart Megazord. Sadly (for our sake), Chris disbanded the team before his graduation, but soon installed a new, younger team to take the reins. Where the team is and what they're doing and which female members are currently "non-boyfriend-free" are unknown.
(As an interesting aside, Chris pretty much ripped off the go-kart vehicles, the "Kart Megazord" and the graduation disbanding and reforming from one of the earlier seasons of the TV show, namely Power Rangers Turbo, the American version of Gekisou Sentai Carranger.)
In Sonichu #9, Allison Amber calls in the Power Rangers to fend off an attack by Slaweel Ryam (or possibly Liquid Chris). The next panel depicts several people rushing off in ridiculous-looking cars. If these are indeed the Power Rangers, they have yet to be seen again. Near the end of the story, the Kart Megazord makes an appearance, with Magi-Chan telling Sonichu and Rosechu that the team, now known as the CWC-Power Rangers, used their Megazord to defeat the giant B-Manajerk and the Merried Seinor Comic. 
In Sonichu #10, to drive those inside the 4-cent_garbage.com Tower out, Chris and the Hedgehog Boys play a song entitled "Revive Zordon". This excellent song (which is sung to the tune of Ted Nugent's "Cat Scratch Fever", of all things) features lyrics written by Christian himself. In it, the band laments that the character Zordon was killed off at the very end of Power Rangers in Space, and demands that he be brought back. The song also serves as a rant against "today's c***py 'Power Rangers'".
Interestingly enough, a few of Chris's other creations seem to derive themselves from various Power Ranger-based villains. The design of Samurai Pizza Bots character Excelina seems to be cribbed from Princess Archerina, a minor villain from Power Rangers Zeo. The most surprising is that Silvana's design and origin is directly stolen from Karone/Astronema, a major villain turned hero in Power Rangers in Space who ended up becoming a Ranger herself in Power Rangers Lost Galaxy.
