Yep. Æ (Ætheflæd) is figured out now! Æ (Ætheflæd) is a sentient, speedy racecar who always likes to go extremely fast! She loves race all around Planet Z (Zachary) all day long. Her fuel is ash as her letter name comes from "Æsh" (pronounced "Ash"). Unlike the official letters from Alphabet Lore, but like some of my Alphabet Lore OCs, She can speak Fluent English. She also understands "Name Speech" (a speech/language where characters only say their names). Her friends who speaks "Name Speech" can understand Fluent English. I was thinking that her voice would sound like R from Alphablocks. (Yep, she would be voiced by Teresa Gallagher) (I wanted her to have a voice actor other than Mike Salcedo)
Mike Salcedo for Alphabet Lore. Everyone else for the sprites! Also, wario100 for the base of Æ. BryanTheAnimator for the base of æ.
