Personally I Thinks using the anime as the main canon is like using the MCU for marvel characters,  plus the anime is not longer the most popular media, since'''  digimon gets more money from the games than they do from the anime, nowadays Videogames games are main source of profits. '''  composites don't work for most characters, but Death battle still uses them.. Those moves are part of renamon moveset, they are not unique attacks  they work just like every attack from pokemon

About the Blood Discussion, yes digimon don't have blood in the manga, this proves it:

also according the official bios, Vampire digimon  drink blood, but Data is interpreted as blood.

"Digimon who have had their blood sucked by Sangloupmon have all the information drawn out of their  DigiCores"

But yes you are Right, sometimes they bleed, but it is inconsistent as hell.
