It would be cool if Ra Moon was the Final Boss of the entire game.

This. Looks. AMAZING!!!

Here are some ideas for Yamato Man

Start: Watashi, dai Kazuo wa, anata o uchi makasu! (I, Yamato Man, will defeat you!)
Taunt: Watashi no bushi no yari o osoreru! (Fear my samurai spear!)
Victory: Nagai Nihon wa raibu! (Long Live Japan!)
Defeat: Watashi wa Nihon, anata o shippaishita..... (I failed you, Japan)

The fact that all his quotes are Japanese is a reference to the fact that Yamato Man hates English.
Translations were done thanks to Google Translate.

Personally, I think the Mega Man sprites need a revamp. In my opinion, it's a case of "this is good, but it could be better." The classic Mega Man sprites are, well, classic, and that's not a bad thing. However, Mega Man, as the main character of the series, could have more detail and just a better look overall.

What's the hidden player password thingy? Just me being curious.

EDIT: Never mind, I found it out while looking up the mechanics....

Hello, I'm accpikachu2, otherwise known as Retro Pikachu. Much like Trouble Bruin, I like Pokemon and Mega Man as well. While I love the official games, I feel like the fan games do just as well as an official game. I love this game's mechanics, leaderboards, and playable characters.

I was thinking of something like this too, only that the "fighters" would be: (note: [Fighter Name] - [Weapon Name])

Mario - Fireball (F. Ball)
Link - Skyward Strike (S. Strike)
Kirby - Star Rod (S. Rod)
Pikachu - Thunder (T. der)
DK - DK Barrel (DK. Barrel)
Fox - Illusion Fox (I. Fox)OR Fire Fox (F. Fox) OR Blaster (B. ster) OR Reflector (R. flector(Fox has too many good moves).
Samus - Screw Attack (S. Attack)
Yoshi - Yoshi Egg (Y. Egg)
SECRET
Pit - Palutena's Army (P. Army)
UNLOCK BY:
Collecting the Smash ball pieces (the smash ball looks like four pieces glued together, so a smashed smash ball would be in four pieces, thus Mega Man would need to collect the four pieces together in order to unlock Pit)

Subspace Bosses.
Stage 1. Crazy Hand
Stage 2. Galleom
Stage 3. The Ancient Minister
Stage 4. Master Hand
Stage 5. Smash Fighters rematches AND Master Hand + Crazy Hand (at the same time)
Stage 6. Tabuu

Just my thought on what would this be
