If you weren't on the internet last week, you probably missed the collective heart attack that happened when Nintendo announced that Final Fantasy VII lead Cloud was joining the cast of Super Smash Bros for Wii U and 3DS. It was a completely unexpected "one more thing" to cap off the Nintendo Direct.
Cloud's inclusion in the game marks the culmination of the childhood dreams of many avid gamers. Realize that Super Smash Bros now includes Mario, Link, Mega Man, Pac-Man, Ryu, Sonic the Hedgehog, and Cloud in a single title. Sadly, Solid Snake didn't make a return appearance after being in Super Smash Bros Brawl, but that's still a damn good crossover roster.
Since Cloud was so out of left field, who else would be a good fit for Nintendo's crossover fighting extravaganza? We're most likely going to see more feature characters outside of Nintendo's own roster, so which characters would be a great fit for Super Smash Bros?
Bayonetta - Bayonetta
Honestly, this is an easy choice for Nintendo. Sure, you could keep Zero Suit Samus around, but why not use your access to a character that fills nearly the same slot? In fact, Bayonetta feels like a superior option all around compared to ZSS; she did everything first and better. Lara Croft (the Tomb Raider: Anniversary Edition version would fit into Smash better than the current incarnation) was almost in this slot, but again, Bayonetta is better.
Bub and Bob - Bubble Bobble
The Bubble Dragons Bub and Bob have been showcase characters of various Taito Corporation titles, including Bubble Bobble, Puzzle Bobble, Rainbow Islands, and Bust-A-Move. Taito is currently owned by Square Enix, so if Cloud can make an appearance, why not these two? In fact, I'd treat them like a new version of the Ice Climbers: two characters, one body.
Inkling Girl - Splatoon
I'm stunned that this hasn't been announced already. With how well Splatoon has been doing for Nintendo, an Inkling Girl/Boy character and Smash level seems like free money. You could do both characters, but I admit I'm partial to Inkling Girl and I'm the one making this list.
Amaterasu - Okami
The lead for Capcom's Okami was an unique addition to Ultimate Marvel vs. Capcom 3 and she'd be a great inclusion for Super Smash Bros. Nintendo could just take parts of her moveset from MvC and Ammy would fit right in. Plus, we'd get an Amaterasu Amiibo!
Bomberman - Bomberman
Deep within the mines of Konami's IP library hides the entire Hudson Soft catalog. Great classic games including Adventure Island, Bonk's Adventure, Bloody Roar, and Far East of Eden, lost to the sands of time. One of the top games in their stable is the beloved multiplayer classic, Bomberman. If anyone could free Bomberman from the dark hole that is Konami, it's Nintendo.
Commander Shepard - Mass Effect
I think this will probably be a point of contention in this list. I originally had another Final Fantasy alumni, Final Fantasy XIII's Lightning, in this spot. Instead, I decided to go with an alternate and more interesting choice. Bioware's Commander Shepard would be a kickass addition to Super Smash Bros. For the purposes of this list, I'm assuming "Commander Shepard" is the fiery-headed woman voiced by Jennifer Hale. I don't personally play FemShep, but mentally, that's the "default" version of the character, an idea that Bioware has seemingly bought into recently.
