A while back I joked that the generic dragon and generic witch shown in the stage builder segment of the direct referenced Dragon Quest and Banjo-Kazooie... and in the spirit of that potentially being a real foreshadow I want to throw my 100% support behind another crazy theory mentioned here, in which Geno is bonus DLC.
Premise:
"The Legend of the Seven DLCs"
- Geno is a bonus 7th DLC fighter
Background:
- Color theory suggests that Orange, Blue, and Indigo are missing.
- In SMRPG, The Seven Stars are also the colors of the rainbow.
- Geno is of course lightish blue, but Indigo / Navyish blue and Orange can very well be represented by some likely and suggested characters.
- For Example, Ryu Hayabusa and Jill Valentine both have classic designs that heavily feature Indigo or Navy / Blue. Doom Marine and Heihachi likewise feature orange either in some their official art or in the logos of their games (Tekken has Orange symbols and Doom's artwork is always generally saturated in orange backgrounds).
- Jill and Heihachi also fit "Mii Costume Theory" in which Mii Costumes for Capcom and Namco will be released with new DLC fighters.
- Other Indigo characters also include Phoenix Wright (dark blue suit) and Lloyd (dark blue pants). Similarly, Crash Bandicoot could be the orange rep.
- As for smashdown, 76 characters become 71 once mii fighters are removed and PT is considered 1 character. Once you add the random button that becomes 72 tiles on the smashdown screen.
This is of course just a joke, but it's totally possible. I definitely wouldn't expect this to be the case at all, but Geno could be a special surprise from Sakurai at the end!
Who better to end the Ultimate DLC cycle in a game heavily defined by fan service? K. Rool, Ridley, and Banjo-Kazooie are in and Geno just might be too!
