Given the settings of the game Roidley was from, don't think it's quite fair to compare him to the original like that. I mean we had the cloned Zebesian pirates that were devoid of any real intelligence to make MB look good/so that she could lead them easily, whereas the original Ridley had ambitious pirates with actual brains accompanying him in the Primes and whatnot, who would also help revive and enhance him after each defeat... Completely different scenarios.
The entirety of the original space pirates were supposedly wiped out by the end of Super Metroid, so Roidley would not of been able to get education of other things elsewhere or backup from them like the original did, nor was there anything in the Bottleship worthy of the clone Ridley to perceive as an ally, thanks to the Zebesians being neutered under the hivemind ****. Best he could do was take control of the mindless creatures of the Bottleship into attacking Adam's men and out of MB's control for awhile, which he did during his adolescent stage so he could have Samus all to himself.
I'm sure though the cloned Ridley, had it lived long enough and gotten to experience things outside the Bottleship it was confined in, would've eventually lived up to the original in potential. Maybe there will be a different cloned Ridley whose not confined to some giant space ship, organizing something against the Federation during the peaceful/corrupt times.
As if it matters to Sakurai. Games with bad ratings have always had material in Smash to some degree, Other M being no exception. Not to say it makes it right (Other M getting more content in SSB4 than anything else in the series is nearly unforgiving), but it is what it is.
And good luck on your hopes there. We already know from the Direct that the Ridley in the game (whatever role he has) is the clone from Other M based on the tail and wings from the shadow, so best you can hope for is Roidley with Meta-Ridley's colors as an alt skin.
Eh, it's fine. The only way it could've been better really is if that Ridley head had them bulging eyeballs somehow like Hulk Hogan or some wrestlers typically do when they're huffing and puffing.
