A neat little discovery made over at The Mega Man Network:
"A few days ago IGN posted some new videos and screens of Mega Man 10. One of the things about the screens is that they featured borders which will fill in the dead space on 16:9 aspect televisions. As it turns out, though, these borders reveal a bit of information when you look at them up close! Namely, it shows off quite a few, if not all of the game’s stage enemies in one of the borders (not including midbosses)."
Apparently, Game Boy Mega Man V's robotic feline, Tango, is but one of the many characters featured within the border! Check it out:
"It’s kind of hard to fix the color, since there’s clearly a blue tint on them. But it’s easy enough to make out that Tango is there. Having made a sole appearance in Mega Man V for Gameboy (and Rockman & Forte on Wonderswan, if you’re in Japan), could this cat finally be coming back?"
Well, what do you make of it? Indeed, the above sprite looks similar to its MMV counterpart, but does this necessarily confirm the critter's presence in Mega Man 10?
