Lucky is the parent of Happy in the Fairy Tail franchise.
Before Happy was born, Lucky and his wife Marl fight against Chagot's order of taking Happy's egg and sending it to Earthland.
Lucky, who is created by Hiro Mashima, has no information regarding any inspiration used to create him. He first appears in Fairy Tail volume 21 and episode 84. His Japanese voice actor is Tomokazu Seki.
Lucky is a white Exceed who has a beard. He has a farmer attire since he and Marl make their own food for a living.
He is a hard to please father who tells Happy how to do things such as how to plow like a real man. Like Happy's catchphrase "Aye!," Lucky says "Kah!" a lot. Interestingly, when Happy and Charle leave them, Lucky says "Aye" as he cries with Marl.
Lucky meets Happy and Charle who are escaping from Nichiya and the other Exceeds. He first yells at them to get off his land, but he tells them to get into his house. After telling them to eat first, Lucky orders Happy to do some chores around the house. Lucky demonstrates how a man plow the field. Lucky and Happy have a lumber chopping contest until they both collapse from exhaustion. Although they exchange laughter, Lucky yells at him that it is not funny. He orders Happy to take a bath.
When Marl explains about Queen Shagotte's order of sending hundred eggs into Earthland, she tells them about how they lost their child. Lucy barges in their conversation and reminds Happy that living is happiness. Lucky gets angry that Marl has told too much, and he tells Happy and Charle to leave their place. As Happy and Charle soar in the sky, Marl asks Lucky if Charle is Happy's girlfriend. Lucky replies that he is too young (about 100 years). Lucy and Marl shed tears as they watch Happy grow up to be a mature person. Flashbacks of Lucky and Marl fighting against the queen's order are shown. (only seen in the anime)
Lucky and Marl appear again when the Earthland lacrima starts to hit Extalia starting on their land first. Lucky and Marl join in to help Happy, his crew, and rest of Extalia to push back the lacrima. During the Edolas soldiers' mass campaign on turning the Exceeds into lacrima, Lucky and Marl are not seen. Lucky and Marl are seen again when everyone who has magic inside them are suck into the reverse anima that Mystogan created.
Like Happy, Lucky has the power of Aera that enables him to fly.
