Short circuited by the Scamp! Panic at the Holo-deck!
Another fresh batch of speculation and wishful thinking for your enjoyment.
The Vete-rodent - Pikachu
Ol' Cheap-a-chu. Favored by newcomers for his surprisingly devastating Thunder attack, and pinchable cheeks, this yellowed vermin makes everybody's lives just a little more difficult. I say it's time to nerf his cute little tail off. Bring him down a few pegs. And also give him more outfits for costumes, like his WorldChampionship costumes.
The Newcomer - Bowser Jr.
More than just a simple Bowser clone, Bowser Jr. would be a devilishly delinquint addition to a roster of goody-two-shoes. Armed with a paintbrush and a temper the size of an air-ship, this little scamp could be an interestingly floaty-yet-heavy character. The paintbrush could act like a spear for most combat, but also serve to paint traps on the floors, or even open up a black hole as a Final Smash. Perhaps he could even have an ability that turns him into Shadow Mario, giving him a change-up in his move list and making him fight more like Mario. That kind of flexibility in his fighting style might help give him an edge, while never really being 'two characters in one' like Sheik/Zelda. Plus, it's canonical, so it makes sense.
For alternate costumes, I'm enjoying the idea of him being decked out in his Super Mario Strikers: Chargedgear, which makes him look significantly more brutish.
Metroid Other M - The Bottle Ship
Few times, she's been around that deck. But she ain't no holo-deck girl. Metroid - Other M is the only Metroid game that's come out since the last Smash Bros., although Metroid Prime 3: Corruption was ignored pretty much entirely. With that in mind, I still felt that the hologram deck of the Bottle Ship could make for a unique stage. The stage could fluxuate from high-tech filled Jungle, to a desert landscape, or a snowy terrain. With this shift, similar to Pokemon Stadium, comes new platforms and hazards. While shifting it could look something like this. The idea is more about how this stage can be visually entertaining while remaining structured nearly identical. Besides, it's either this or we go for the easy answer of "the scene where you fight Ridley, adding in a couple of pass-through platforms, and making the space-dragon himself a stage hazard." It's not a bad idea, it's just the easy one.
Music for the Holodeck
Metroid Other M - Debriefing
Metroid fans of old will appreciate this callback to Super Metroid.
Metroid Other M - Ridley Batttle
People can say what they will about Metroid Other M, but if that game did one thing better than all the other games it was the Ridley theme.
Super Metroid - Upper Brinstar
A personal favorite from Super Metroid, I'm surprised it hasn't been used for Smash yet.
Metroid Fusion - Ishtar, Gedo Battle
A little love to my favorite 2D Metroid, Fusion's soundtrack didn't really strike as memorable in a lot of places, but when it did, it did well.
Metroid Prime 3 - Battle with Rundas
Excellent, excellent use of music for a battle. This song stands as one of the best battle themes in a video game, period.
Any Metroid tracks you feel I missed? What's your preference for a Metroid stage. I've got one more in my hat, so keep an eye out for it!
-Make it a good one.
