Makken Jokin

Personal Gunmen: Moshogun Makken is a fairly silent man who is an important part of Team Dai-Gurren, but has rarely spoken or gotten much screen time whatsoever. He has his own Gunmen, Moshogun, which is based on an ancient samurai. After the timeskip, Makken is married to Leite with three children. Sadly, he is killed in the first deep space battle versus the Anti-Spirals, after sacrificing himself to stop a large Anti-Spiral missile from destroying the Super Galaxy Dai-Gurren. In the epilogue, a memorial site, in the form of a sword, is seen in his honor right alongside Kamina and the other members of Team Dai-Gurren. Makken has the same voice actor as Kamina, though he is credited as "Leo Kaminaga." Leo Kaminaga, when written in hiragana, is an anagram for "ore ga Kamina," or "I am Kamina." - Wikipedia
