Synopsis / Summary / Plot
We begin with Jack Of Hearts kissing Ganymede. But she protests that they agreed that their relationship couldn't be physical while he was trapped in his armour (which keeps him from exploding) and she's devoted herself completely to the destruction of Tyrant. But Jack shows her that he can safely remove his armour now until he's completely naked. She joyfully strips off to join him and they start to make passionate love ...
... until Ganymede wakes him from his daydream and urges him to concentrate on co-piloting their spacecraft to a safe landing on a moon of Jupiter (Ganymede?). Thanos and Terrax are following them in a cloaked craft because Thanos wants the information that Terrax tells him Ganymede possess about Tyrant. The Titanian wants the info on which to base his strategy of attack on the powerful foe. Ganymede has come here to find out if she's really the last of the Sisterhood, ancient enemies of Tyrant, as a computer told her when it awakened her from suspended animation (Silver Surfer #80). The Sisterhood hollowed out this moon and built a city within where the Sisters received their martial training. (Apparently some of the Titanian Eternals in their similar city within Titan, moon of Saturn, knew about it - but seemingly not Thanos.)
Ganymede leads JOH into the moon where their way is blocked by a muscular Sister. Jack leaps in to take her on, ignoring his companions protest. The Sister beats him back until Ganymede switches her off by pushing a button on the back of her neck - it's only a robot. She then uses a doorcode to enter the main area ... which they find in ruins. On the surface Thanos destroys G&J's ship before he and Terrax follow them inside. The Sister fondly remembers her time here as a girl being trained, before she leads Jack to the cryonic chambers which may hold more sleeping Sisters. Meanwhile the robot Sister has rebooted to challenge Thanos and Terrax. Terrax blasts her with his axe, and when that doesn't work he chops the robot in 2. Ganymede opens 1 of the cryonic containers but the Sister within is desiccated. T&T follow a trail of open doors to where G has checked that all the Sisters here are dead.
Thanos says he's come for the woman. Jack says over-my-dead-body. Thanos tells Terrax to oblige him. Terrax blasts JOH but it is Thanos who pummels the hero while Ganymede takes on the other in foot-to-face combat. The 2 fights continue with G surviving an axe-blast and JOH blasting back at the Titan. G is doing well against her opponent, disarming him of his axe with her staff. But Thanos defeats *his* opponent and KO's the female from behind with his power-infused fists. The dastardly duo leave with Ganymede, and leave Jack to die.
