Leviathan (FFG).jpg
As the offense, after destiny is drawn, you may trade one home planet with the defense. Your planet moves to the defense's home system and vice versa. The encounter immediately ends successfully. Afterwards, give this flare to the Leviathan (or discard it, if Leviathan is not playing).
Your worldships may contain any ships except the defense's ships. Other players' ships on your worldship count towards your side's total and those players are automatically allied with you for this encounter, but may not launch additional ships and do not receive a colony if your side wins.

Leviathan is an alien that can attack with one of his planets that has only his ships on it. The planet adds an extra 20 to his side.

The card depicts the Leviathan as a massive space-faring crocodilian whale-like creature with structures built on its body accompanied by spacecrafts, Its jaws have two pairs of eyes on them each and opens up in 3 long slits lined with teeth lining the insides.


Edition Power Text History
CI You have the power of Worldships. As the offense after the hyperspace gate is aimed, you may use this power to choose one of your home planets that has no opposing ships on it and send it through the gate to attack as a worldship. Take the worldship (with all of your ships that were on it) and place it on the hyperspace gate. After encounter cards are revealed, add 20 to your side's total, plus 1 for each ship you have on your worldship. If you lose the encounter, return the worldship to your home system, sending all ships on it to the warp. If you win the encounter, return the worldship to your home system with your ships still on it it, although you may leave one to four ships behind on the planet you successfully attacked. Immense and powerful creatures, the Leviathans consumed every resource on their own worlds until they themselves became like planets. The Leviathan fleets, now stationed within the fleshy folds of their masters, scout out new worlds for the Leviathans to envelop. The sight of a world-sized entity gating in through hyperspace often causes madness and hysteria on the targeted planet, but it doesn't last long.



Leviathan's strength is that it has a much larger chance of winning as the offense. Sending a worldship can allow Leviathan to win with low attack cards that would be of little use to other aliens, so he doesn't have to keep trying to ditch his hand looking for 30s and 40s. The extra power can be used to overpower Citadel's defense boosts.


There are many aliens who make the Leviathan's brute force irrelevant. Loser and Anti-Matter make the extra twenty work against Leviathan if they catch him unaware; of course, Leviathan can just choose to not send worldships in encounters against them. Pacifist can easily sidestep Leviathan, as with any combat alien.

Because of the condition that a worldship can't have an opponent's ships on it without the use of its own flare, the Leviathan is vulnerable to aliens that can get colonies without having encounters, like Disease. Leviathan is especially afraid of Locust, which can remove planets from the game permanently.

Playing as Leviathan[]

Leviathan has to keep up a good defense in order to keep its offensive advantage. Its power decreases the need to play high attack cards as the offense, so these cards should be kept for encounters as the defense. Force Field is good for keeping other players off of its planets.

Because worldships are most effective when lots of ships are piled on them already, Leviathan should watch out for Mobius Tubes and Rifts.
