Where is this stated? Also are they still physically attached to Arceus? If not then just because they came from his body does not mean Arceus has their powers. However, I said LT, or Lake Trio, not CT.

Dialga is omnipresent in his own realm alone and his physical self must time travel. He is infinite for being time, but being 4-D =/= transcending time itself and gaining Immeasurable speed.
I agree with Kep here.
@Prof
Nothing on Dialga's page says he is the multiverse. He helped
create the multiverse, hence creation trio. It seems like Pokemon is confused over whether Dialga is the creator and master of time or if he literally is time. What scans indicate that Dialga is literally outright time in a conceptual way?
Also, you don't know that "souls didn't just magically appear". Souls in a lot of verses are just universally constant. No one needed to directly create them for them to exist and even the gods of the verse still have them. Arceus himself may have a soul since he has never been stated to lack one, unlike beings such as
Chuck from Supernatural. Unless you have direct statements showing that you are soulless or totally predate souls I don't think you can just assume they don't have souls or else every single creator god lacks a soul and gains immunity to soul manipulation, which is absurd.
When does it say that they literally created souls? When Mesprit, Uxie, and Azelf arose, Emotion, Knowledge, and Willpower followed, respectively. The three aspects are what Pokemon identifies as spirit. This "spirit" is outright and probably different than literal souls. A ghost or disembodied soul can be absent of emotion, knowledge, and willpower, yet still exist. Just because the three aspects are not present in an individual does not mean that their souls cease to be, nor can we assume such until proven otherwise.
