This msg is spoilerized (sry i cant find the exact color of the background of this forum, or may be there isnt... so ill just put a big space b4 the spoiler part comes), the spoilers are black colored, since thegreatdekutree and may be others may not want to be spoiled of the story in SSE. The black info is just about DDD in SSE and my opinion and why i think that he is a good/bad guy in SSE.
In SSE, some things are sorta vague (or maybe cus i looked at scenes out of order) but i had some trouble deciding what this guy is trying to do, and that stuff. But in trophy descriptions it clears it up more, which is good.
WARNING WARNING SPOILER PART BELOW!!
In SSE, i thought Dedede was a bad guy since he turned Luigi into a trophy. But i didnt realize that he didnt use a trophy gun! my friend noticed this tho. I thought that dedede,wario,ganondorf,and bowser were sorta competing to see who gets the most trophys cus the ancient minister would award them or something, and i thought thats may be why DDD is stealing wario's trophies. but in tabuu's trophy description, (im not sure if its tabuu wings or just tabuu trophy), it says that DDD puts a revive thing (the gold badge thing) onto ablebodied characters because he knows that tabuu was gonna wipe them out, so after a certain amount of time (or may be it triggers after tabuu attacks), it revives the characters. So, dedede actually did a good thing. But i guess doing this also shows his misguided sort of self, cus he turns luigi into a trophy without warning... then again i dont think it would really matter... lol, again its like miscommunication like som1 above me said. but, ya DDD is considered (i would consider him) as a good guy, may be a neutral guy but definitly not a bad guy unless if i missed a scene
