Simon (Gurren Lagann) is one of those characters who may not have wanted to be a big fighter initially but he ultimately buckled down and stepped up to the plate. Yomogi also faced his fears but ultimately his latent power just wasn’t quite as intense. In a straight fight he is definitely not going to be in a position to take Simon down. The gap between them is simply much too large. Such is the power of the Gurren Lagann! Simon (Gurren Lagann) wins.
