The starship that Emeraldas uses in the first battle scene was her first command before her permanent ship, the Queen Emeraldas. That version was probably Tochiro's other design after the Arcadia.
Huh. So in this version Tochiro doesn't actually upload himself into the Arcadia's HD, he just regular haunts it, I guess? Also, it doesn't seem like Emeraldas to chase a corpse for the rest of her life... :\
Let me get this straight. One guy, with a handgun, scared an entire fleet of battleships into leaving the planet? Batman, Punisher and Wolverine, all put together look like a bunch of sissies compared to Harlock.
You should have seen them in Gun Frontier, ArcaJ! To answer your question, Emeralda appears in Arcadia Of My Youth, Galaxy Express 999 and even has her own TV special Eternal Voyager Emeraldas.
