I personally think Low 1-C for all Dinosaur King is iffy at best, I dunno, something tells me they don't exactly transcend an infinite multiverse by a whole layer. At the very best case, a "possibly" Low 1-C. Not "likely", just "possibly" at most.
But I don't mind 2-A Dinosaur King though. 2-A is where it should comfortably lie around at its best.
I guess that still makes Dinosaur King the second strongest show to ever be licensed and dubbed by 4Kids after Pokemon, pretty much beating 2003 TMNT with Time Scepter or War Staff in that position.
So yeah Pokemon and Dinosaur King both reign supreme as 4Kids's two strongest acquired series (assuming Anime Arceus could also scale to being Low 1-C like his game counterpart in terms of lore with The Mirror World thing, I think and for the record Anime Arceus was voiced by a 4Kids voice actor, Tom Wayland, in both movies he appeared in if I'm not mistaken).
2003 TMNT still beats pretty much everyone else on the 4Kids dubbed series list though.
