QRD:
>Flame Plate explains the plates are made of the power of defeated giants
>Earth Plate explains that the plates are also the shards of the universal creation
>pmyth5.2."AUSU" from Leak directly explains this
>states that in the beginning there was nothing, then the cosmic egg appears and when it hatched, arceus(Aus) was born and the eggshells of the cosmic egg became giants of every element that attack Arceus out of "Jungian Fear of Existing after an eternity of non-existence." Arceus kills all the giants until they are nothing more than plates.
>Giants are described as "きょだい" specifically "Kyoo~jin" which emphasises "Giant Giants" relative to other instances of other giants like the lesser regis being called 巨人 "Kyojin" just Giants.
>Regigigas is referred to as the "きょだいポケモン" or "Kyoo~dai Pokemon"
>Leaked Emetology doc explains Regigigas' concept as being "きょじん" 'Kyojin" specifically like the giants mentioned in the flame plate
>There was no normal plate until Legends Arceus. This lead most in the Japanese community to conclude that Regigigas was the normal type "Kyoo~Jin" that was defeated but not turned into a plate, just beaten and weakened by arceus.
>Slow Start has the same premise as the move "Curse" that slow and curse are a pun together and imply that Regigigas was Cursed for his actions again Arceus.
>Regigigas have Slow Start in every single game no matter what, even spinoffs to emphasize that he is always cursed by this even when abilities aren't present
>Regigigas tries to remake his fallen giant brothers out of earthly materials in the form of the lesser regis
>Arceus sees all of them as a threat and has humanity seal all of them

This explains why in the manga and anime Regigigas will throw hands the second he sees a creation trio member as well as why he is so fucking strong that he can throw palkia and Giratina around. He is the prime cosmic egg giant just in a weakened state.

>Flame Plate and Earth Plate talk about how the plates are made from the cosmic egg and dead giants
>Who are the giants?
>Regis are called "the legendary giants"
>etymology doc found in the leak explicitly calls the giants a race and uses the same language in explain Regigigas
>Leak explains the Earth and Flame Plate directly in PMyth5.2 "AUSU" stating that cosmic egg broke open, the shell pieces became giants of every type, they attacked Arceus out of "Jungian Fear of Existence after an eternity of non-existence." Arceus kills all of them and makes them into plates except for a normal plate
>Fast forward to Legends Arceus, the plates awaken Regigigas and make him attack you, he knows what they are, dead giants
>Regigigas is holding the long forgotten "Normal Plate"
And then from there, Japanese fandom fills in the gaps from implications that are only legible in the Japanese version relative to the English
>Slow Start is a curse as "slow" and "curse" are a pun
>Regigigas was cursed as being one of the giants that rebelled against Arceus and was forced to carry the continents in his weakened state
>then he tried to remake his brothers out of earthly material
>Arceus then commands humanity to seal up the regis for being too dangerous

Actually there is a convincing case that it is canon. The japanese wiki actually state it as a matter of fact:

>In the beginning there was nothing
>Suddenly Cosmic Egg
>Eventually Cosmic Egg hatches, Arceus is born
>Cosmic Eggshells form into giants of every elemental type
>Giants attack Arceus out of Jungian Fear of Existence (existing after an eternity of non-existence)
>Arceus is beaten down but gradually grows in strength, slaying every last giant except Regigigas, beating them into nothing more than Plates. Leaves Regigigas alive as it doesn't need a normal plate.
>Arceus curses Regigigas with weakness and slowness. Forces him to carry the continents of the new world she created.
>Regigigas tries to remake his fallen brothers out of earthly materials
>Arceus has her followers seal up Regigigas and all of his new "giants" just to be safe
>Will Regigigas and his army of giants ever have their revenge on Arceus or just try to chill out on earth?
