Space Battleship Yamato - Season 2 Episode 18 The Decisive Battle. All Ships Ready!

Despite its setback, the Comet Empire orders its fleets, under the combined command of General Bleak, to gather for full and immediate attack. Captain Gideon, realizing the urgency of the situation, overrides the Earth Defense Committee and calls in all Earth defense forces to rendezvous at Titan. Meanwhile, Princess Invidia knows that she must have Desslok killed before he can talk to Zordar. She arrives to lead him out of his prison cell whereupon she plans to have him shot for trying to escape. But, the perceptive Desslok has already forseen this, and has made real plans to escape. Leaving the cell, he takes Invidia hostage, and ushers her to Talan's awaiting air car. They dump Invidia at the runway and, with skillful piloting, escape the Comet Empire fortress. Prince Zordar realises he was deceived regarding Desslok, and grants him his flagship in return. The Argo warps to join the Earth fleet.
