When Angel Garza debuted in WWE, his name had been pronounced “An-hel”. That is the proper way to say it in Spanish. The American version, which pronounces it how it’s spelled, has been used on WWE TV in recent months.
In an update on this, it was Garza’s idea to start using the name that way. Garza wants the character to be “someone that is an angel but acts like the devil.” That is the plan for merchandizing as well.
