This fic has a fairly interesting idea: what if Nia had an elder brother who's more than devoted to continue his father's legacy and who shows up pre-Time Skip? Ribo Soma Teppelin is more than a Dragon Their Feet: he fully knows about the capabilities of Spiral Power and went on to engineer a race of Transhuman Aliens, every single of which can fully count as Simon's Evil Counterpart. Add in the fact that he has superior numbers AND firepower and the Dai-Gurren Brigade is in deep shit.
