The year is 21XX. Reploids are commonplace now, after Dr. Cain rediscovered Dr. Light's old lab and based several designs off of Dr.Light's original, called "Megaman X." X, meanwhile, has joined the Maverick Hunters, and works with unit leader Zero under the command of General Sigma. It is their job to terminate rogue reploids, those who have become violent.

There are plenty of awful cliches and trends in the anime industry to complain about, but at least one seems to have ended. The trend of making anime adaptations of old video games that didn't really have a very complex or good plot and simply had no business being adapted into anime. In the old days we got horrible anime adaptations of Sonic, King of Fighters, Voltage Fighter GoKaizer, Darkstalkers, Megaman, Kirby, etc. Now besides Pokemon it finally seems to be over. This is Megaman, which falls between the best and the worst adaptations of old videogames and is just stuck in mediocrity. Why would read more

Irregular Hunter X: Day of Sigma, or if you are familiar with the english localization of Megaman X, Maverick Hunter X:Day of Sigma. This OVA is well worth the watch, especially if you are/were a fan of the orginal Megaman/Rockmam X franchise. Although to those who frankly couldn't get into the franchise/never heard of it,this will be your one badass starting point. Most anime companies have tried to adapt retro video games,and have failed the majority of times, which gives OVA's like this one a bad name. This anime serves as a turning point that will eventually set a present for future game adapted animes, read more

Megaman X was first released in 1993. The series was the first of many spin-offs of Capcom's Megaman franchise and has been highly successful, receiving eight sequels (one being the Command Mission RPG), and a prequel OVA. That's right, back in 2005 Capcom and Xebec combined efforts and came up with an OVA prequel for the Megaman X franchise. Let's take a look at Maverick Hunter X: The Day of Sigma.

The story is pretty simple. It's about how Sigma went from being a maverick hunter, to the head maverick. For those of you who aren't familiar with the games, reploids are robots with the power read more

This one-off Mega Man X anime was included as unlockable content in the PlayStation Portable's Mega Man Maverick Hunter X, a remake of the first game in the series. I beat the game, which was the prerequisite to gaining the video, but for some reason I never watched it. It was a little unfortunate, as this bears the distinction of being the best Mega Man anime ever made. That's not saying much considering their generally average quality and the fact the games themselves were never strong on story, but if you've gained an attraction to the world and characters simply through constant exposure among the read more
