I'd listen to the song that plays in that opening (Guren no Yumiya) and day dream all about it. Re-imagining the opening act with Leon and Vagus looking down at the corpses of their dead comrades, titans roaming on about inside wall maria, an army of pokemon including Leon and Vagus lined up into a formation as they did their salute, the walls breaking into pieces and Leon floating mid air with wide and vigilant eyes as he looked up. Then the scene changes with Vagus blasting hookshots from his 3DM to fly across some houses, Leon following behind him and then free running on the rooftops, swiftly making his way behind a titan, jumping high up and spinning down, slashing his sword hard behind the titan's neck as it dropped dead. That would be one heck of an awesome sight I could only wish to see. ;w;
epic as hell!!!
Leon looks well suited for the job.
