Zero Nightmare: Owari d- UUUUUUUUUUUUAAAAGH

Well damn.....and here I thought that beating Infinity Mijinion and Nightmare Mother flawlessly was virtually impossible. Clearly Serg is some kind of platforming god

3:28 My fav boss!

Sigma literally becomes a robotic version of the colossus titan.

Infinity Mijinion with no damage... you sir, are a God

Can we have a look at the backgrounds for Nightmare Mother, High Max, Gate, and Sigma? Take a look at the two figures for a moment. Nightmare Mother shows an Incomplete 'Demon' with some kind of headless 'Angel' standing next to it, fully complete. But then, for Gate and High Max, the Angel is suddenly chained and decaying, while the Demon is rebuilding itself, hunched as if dormant. And finally, Sigma's room shows a completed, roaring Demon while the broken and decaying Angel stands beside it.
Symbolising Sigma's return to life or Gate's path of darkness?

I still loved all the mega man games, I'm glad Capcom made them.

How many attempts did it take to No Damage Infinity Mijinion? That must have took a lot of patience. Cheers on that one mate.

I'm sorry in advance to anyone who had to endure the fight with Gate.

Quite the feat for you to not be damaged on Infinity Mijinion. Great job!

The miniboss at 14:29 looks like Megatron.

35:53 I think X was referring to Double from MMX4. 🔥

I like to think that the Maverick Virus just turns their victims into Zombie-Androids which is why X & Zero can finish them off cause of theyre repeated patterns

31:43 sigma looks more like Godzilla

Lumina looks like Megatron.  Amazing you could do this, now if you can do it as Zero, then I'll be shocked.

High Max: Death bull. Mudota.

32:29 - Someone should do those lines in a death metal scream.
