hmm very interesting take on how the meeting between these two characters would go. However, I think this would be a better video if you provided some backstory as to how they ended up together in the first place. I clearly understand X's motivations, (see how long that pink ball of play-doh lasts), but it is hard to believe that would be the first thing that happened when they met. Kirby perhaps did something to anger him? Also, we get no insight as to Kirby's mind, which would be nice.
Regarding the attacking sequences, it seemed like this is spot on how it would go if a merger like this were to ever happen in real life. Albeit X did not have a chance to utilize any of his special abilities. Now that I think of it, both are characters that absorb their enemies powers... I think not exploring that was a big missed opportunity.
The animation is overall smooth for sprites. Maybe the fatality could have been a little more explicit, but the idea came across. I could almost feel kirby's pain when he expelled Megaman from within.
2.5 stars. Maybe do a sequel? (or prequel, wink wink)
