Has the splounge drawing already been drawn? I jump some pages, so I would like for you to keep me updated
Also, I would like to mention something, there is no such a thing as "Ridley's spot is as a boss", if you think that's because being playable would take away his power, look at Bowser, in 64, if you throw him out of the arena, he would come back, in Sunshine, he's huge, in Galaxy, he's even more huge, in 3D world he can climb a freakin' gigantic build and destroy its walls like it's nothing, Smash took away all those awesome things that make Bowser "Bowser"
Look at Ganondorf too, people don't complain about he loosing his swords, magic and trident, it's because he's a fu***** clone, if he wasn't no one would complain.
The things that makes Ridley "Ridley", is his inteligence and merciless personality, it isn't difficult to translate this into Smash, a competitive player would be just as unpredictable as Ridley is in Metroid, put some powerful K.O. moves and BAM you have Ridley
tl;dr they took more of Bowser's and Ganondorf's characteristics than they would need to take from Ridley
