Soukou no Strain

Both of them show a desperate struggle against a foreign enemy using mecha that can either be a blessing or a curse. The Strains are only good if you have a mimic for them while the Fafner's slowly eat away at the pilot. Both have a major dramatic climax that leads to the resolution.
