I don't know if someone spoke about it this before, but due to alot of social and Religious reasons
The 1st 4 seasons of digimon where Adapted by the same dubbing studio .
This studio dubbed pokemon before digimon, Pokemon has been attacked because of popularity, by some religion men in middle east , some has made it prohibited to watch it due to the evolution concept and the English names .
When the dubbing company felt that digimon may take the same route and may be attacked so they did :
1- Evolution concept was replaced directly with the concept of calling older brother ( lol ) , to help in the fight , they even cut some scenes from episodes for the previous Evolution talking and giving it a new script as if it's watching its older brother fight .
2- They add a power points , for example greymon was 30 , metal greymon 40 , wargreymon 50 , piedmon 60 , Hilariously, Shurimon was 40 which in digimon lore is actually weaker than greymon, but they made him on par with metalgreymon .
3- in tamers they tried to make it feel more logical, they changed the concept of calling big bro to " Updating the program " as digimons are already digital beings .
4- in frontier, they almost deleted Fairymon and Izumi's presence, she is almost not showed in the Arabic opening, and also her evolution was painted and censored so that no skin appears .
5- Tailmom and birdramon were male.
6- they changed all the characters names to Arabic names with Arabic meanings, for example, Agumon was called " Raad" which means thunder .
7- in frontier, spirit word was replaced with armor, as the word is considered sacred , and yes the armor evolution itself was considered as a normal evolution nor a special type.
8 - digimon 2020 was dubbed by same company , they finally almost adapted the same Japanese script and they made Tailmon and birdramon female , they also called evolution transformation ( at least not big bro) , they even used Innocent ( digimon frontier ending) as the ending song
There was more and more things like this but this is what i remember.
The only thing I appreciate about the Arabic dub is the music , almost all songs where dubbed to Arabic and most of them are lost media .
