Tyrant

In-game description:

The Tyrant is the most powerful ship in Planet Commander. It boost the highest health out of any ship, and at base health has 30,000 more health than the Invictus, enabling it to take massive amounts of damage and still come out on top. The tyrant boosts a reasonable speed for a ship in general, possibly due to the size of the engines.

The Tyrant should be used as an in-your-face assault ship, blasting through tough enemies and tanking damage for allies, using its health to out-match and crush enemy forces. The large size of the ship makes stealth and hiding almost impossible, and negates the advantage it holds.

Despite the massive health, the Tyrant has no more max damage output overall than any other ship with all slots unlocked, and as such someone with better weaponry can often win against it. As such, the Tyrant should always hold the best weaponry a player has to offer, and if a player has multiple Tyrants, should all be on one ship.

Trivia:

The Tyrant is considered a super-dreadnought, which is fairly realistic to the power it holds, but since the Invictus is also considered a super-dreadnought, the label may be meaningless.

The Tyrant takes designs from the Resurgent-class star destroyer from Star Wars, but the smaller bridge makes it seem like the Tyrant would be similar in size to a super-star destroyer.
