Mighty Jack

An evil criminal organization called Q has plans for world domination, so a high-tech crime-fighting unit is formed to fight Q; this unit is called Mighty Jack. Mighty Jack operates out of a secret base from which they can launch their state-of-the-art submarine/jet hybrid vehicle.

Q kidnaps a man named Mr. Atari because they want the secret of Mighty Jack. Mighty Jack unit is deployed to rescue Atari.

Q then uses stolen research plans to develop a new ice that stays solid at high temperatures, and also an instant-freeze gun that uses this "hot ice." Q destroys an artificial island with its instant-freezing weapons and then uses a iceberg made of hot ice as their new base. Mighty Jack is called in to fight Q again.
