Gatchaman: Red Impulse #1

Captain Kentaro Washio takes Ken the Eagle on a merciless training run, but receives a tip that Galactor is building a weaponized “attack city” designed to lure in Gatchaman and kill them all.

Without Doctor Nambu’s knowledge and with no time for reinforcements, Kentaro goes in alone - and walks straight into Berg Katse’s trap, where even the “citizens” are killer machines. Outnumbered, beaten down, and armed only with determination and a service pistol, the captain must tear down an entire city to protect his team - especially the son who does not know about their connection.
