Gurren Lagann memes stem from the 2007 Gainax anime series 'Tengen Toppa Gurren Lagann,' celebrated for its over-the-top action and indomitable spirit. The most famous templates involve the protagonist Simon and his mentor Kamina, specifically focusing on the phrase 'Believe in the me that believes in you.' These memes are typically used to provide aggressive motivation, parody shonen anime tropes, or highlight moments of extreme escalation. The iconic orange pointed sunglasses and the 'pointing to the heavens' gesture have become visual shorthand for confidence and determination throughout the internet anime community.
