In a large bowl, combine the green chilies, sour cream, and softened cream cheese using a hand mixer.
Using a spatula, add in the pepper jack, cheddar cheese, red onion, and jalapeno. If a spicier taste is desired, leave the jalapeno seeds. If a mild taste is desired, remove them.
Incorporate the fiesta corn into the dip, leaving ¼-½ a cup for additional garnish for color. Taste and season with salt and pepper as desired.
Top with green onions as an additional garnish.
Refrigerate for at least an hour to chill or until ready to serve.
