OK, so we've seen this three times already. Still, the Norse mythological themes is pretty amusing. "We named this mecha after Fafner, a giant who turned himself into a dragon to protect his treasure!" Sure -- but did you also know that said giant killed his father first to gain possession of the treasure in the first place? And the ground-control unit is called the 'Sigurd unit'... Right.
It might prove to be an amusing series, perhaps the Norse mythology will play a role in the plot.
