@Silentpixels, this response to the first link should be enough to provide a panorama.
0:00 and 0:19 = If this is to go by mini-games, then he can't inhale bombs ("Egg Catcher" -
Adventure, "Speed Eaters" -
The Amazing Mirror and "Speedy Teatime" -
Squeak Squad).
0:52 = The "veritable black hole" statement is a mistranslation…

1:58 = That's a valid one; apparently, his body composition lets him withstand fire, freeze and other non-physical hazards.
2:22 = He's already piloting the Warp Star by the time that explosion occurs.
2: 39 = That explosion is of a spell's end, not explosives; turns the vines into sparkling remains, not burning ones; and sends him flying only meters away… Also, he has to be saved from falling afterwards.
2:55 = "He may end up destroying a nearby planet or two"… That must be house by house, considering the content of the series.
3:07 = Whatever collapses after Magolor's defeat does so because
he's created it .
3:35 = Another valid one; Copy Abilities are at that level… It's noteworthy that the makers of the video used game mechanics.
3:48 = Not only doesn't that "black hole" destroy its surroundings, but also light doesn't look like that when pulled by real ones, the time dilation in the SNES version is actually video slowdown, real ones that size last much longer, and that "one" doesn't explode.
4:01 = Dedede being around when the Sparkling Stars and food are back in Dream Land would be unsettling for everyone, so that "feat" is a story mechanic.
4:13 and 4:34 = Those ones occur in non-canon games; and even if they occurred in canon ones, they'd be outliers.
4:46 = Another valid one; Friend Abilities, which use the Ancients' power, are among his most powerful moves, and those boulders' sizes scale to his height of eight inches… And GMs were used again.
4:58 = He needs the power of the Sparkling Stars to lift that castle, which is small room-sized and
bigger on the inside .
5:14 = Another valid one; Super Abilities, too, are among his more powerful moves and can destroy boulders whose size scale to eight inches… And GMs were used again.
6:11 = What star explodes?
6:24 = No comment here.
For starters, how does the second paragraph of my last reply affirm misinformation?
