Both are stories of a company build up with people with superpowers in fictional versions of real life world wars. -Also, both have ridiculously strong protagonists from the start.

Gurren Lagann took everything Outlaw Star did right and improved its story on it. There are too many similarities both plot wise and character wise. 1- Both are stories of two brothers without a bloodline. 2- Both have epic space fights. 3- Both are stories of a crew that built for same reason 4- Both are making philosophy on human nature and machines 5- Both are road stories with their own way 6- Way too much similarities I can not list in there because of Spoiler restriction generally plot wise
