Assist Trophy: NiGHTS

I never played Nights, but it has a decent fanbase. I don't think it's important enough to get a third party character slot, but deserves some recognition.

Assist Trophy: Adam Malkovich

Adam Malkovich from Metroid the Other M should be an assist trophy for sure. I would say he would make a good character, but I don't think 1 game as a supporting character at this point cuts it. I don't even know if much wider known characters such as Waluigi should make the cut, so Adam is out of the question at this time for me. Adam would be a great addition to the assist trophy collection, though. He could go out and shoot at you similar to Saki from Brawl.

I think if Adam continues to play an important role in the Metroid series, he would be a great addition to Smash Bros., especially with a major series so low on character options.

Metroid Enemies

 

I understand that there are plenty of Metroid Prime enemies, but I believe that most Metroid Prime enemies are a bit too violent for Smash Bros. I'm sure Nintendo could make them more innocent, but that would both ruin the Prime trilogy's reputation and make gamers less familiar with them in comparison with classic Metroid enemies from the 2-D games.

Zero Suit Samus

First Appearance

Metroid

NES

1987

A secret in the original Metroid, only by using certain codes (most popular Justin Bailey), but in Metroid Zero Mission along with more recent games, Samus can completely play as a different character without her suit. We'll most likely see her return with this form with the same or at least a very similar moveset.
