(Oops. Wordswordswords. My bad. Thank you, Jasonsith.) @DMB_1 : My reply to this thread kinda addresses that. Quoting myself:
"Robbie's best hope is to use the Littleizer on King Dedede, or the Memory Zapper, but they're not in his Standard Equipment, & SBA has the default battlefield as Central Park, New York, so he's nowhere near his equipment.
If they WERE in Lazytown, Robbie could use his knowledge of the layout & maybe his invisibility &/or teleportation -He has that?- to get to his lair."
My best guess as to why they're not listed is they're something that were only used in like, 1 episode each, & not pulled out of hammerspace, but rather, crafted, likely in his lair. He hasn't shown that he can't pull them out of nowhere, especially if he spends most of their episodes clearly carrying them around rather than materializing them when he didn't have them.
AFAIK, typically, we go by what's on the profiles in matches.
And even if he did get it, or could hammerspace it out -AFAIK, he can't do that- he'd still have to aim it & use it in the fight before Dedede breaks it with his hammer or inhales it. And given that both are bloodlusted, & this is Anime Dedede, I doubt Robbie will even have time to catch his breath; Bloodlusted anime Dedede would probably be chasing him and swinging his hammer every chance he got.
Robbie being bloodlusted himself, too might mean he'd be too caught up in the fighting anyway.
Well, until either or both of them realize they can't really hurt one another. But then it turns into an endurance contest where one has High Stamina (Dedede) & the other has Unknown Stamina, but has been shown to be lazy & physically unfit.
At best, Robbie could try to exploit the environment of Central Park. Dedede has Unknown Lifting Strength... but he wields that huge hammer. So it's doubtful Robbie could overpower Dedede & drown him.
Would trying to use power lines to electrocute someone with Large Building Level, possibly City Level durability work? What could he use to set off an explosive?
As an inventor, Robbie is a scientific genius.... But can we really say he'd have the materials in Central Park to make a Deus ex Machina or the like? Him working outside of his lab, with mundane, Real World materials & making a super-machine of some sorts, possibly one that's even unprecedented for him by not being something he has on his profile -Ex: Having higher AP or different hax than his other inventions- seems unlikely, IMHO.
Plus, he'd still have a hostile Dedede after him, & I doubt Dedede would let Robbie try to invent much; Even if he can't harm Robbie, Wall Level can smash a lot of different materials.
I'm not sure how Robbie's invisibility works. In theory, it could buy him some time.
But ultimately, he's against an opponent who's Durability outmatches his weaponry & who's Stamina is probably good enough that Robbie will collapse of exhaustion before his opponent does, leading to Robbie losing by Incapacitation. Meanwhile, Robbie is too far from most of his game-winning hax to employ it.
Almost poetic that one of the most likely ways he'll lose is by effectively falling asleep.
(And also, Dedede may be able to just BFR by smacking him away with his hammer. He'll survive it, but that doesn't mean he's getting back into the fight.)
