Mega Man X5 - Dynamo (Sega Genesis Remix)[V2] 

My theory: Before the events of X5, Doctah Wahwee (as Isoc) created him as his latest DWN robot, improving on the things he did with Zero, taking some stuff from X and adding reploid improvements. That's why he is highly adaptive (using a buster AND a melee sword, plus learning new moves and using the Nightmare to boost his power), he is immune to the W Virus (and all its variants) and has a very independent and intelligent behavior (he isn't being random, he clearly wants to create havoc so the events of X5 and X6 happen). That's why he can't be catalogued as a Irregular / Maverick, he is acting out of free will, and he doesn't mind what side he is fighting on as long as he has fun.

And a buster!

he's presumably the favorite of an artist who worked on quite a lot of the X games, however, that artist stopped working on them after X6 and X2 GBC came out, so starting with X7, the artist was gone, and so was Dynamo. though, X7 is also a pseudo-reboot, so there's that.

"in happier"?
