Because I like the Mantis warships, I was thinking of a Mantis flagship which you could encounter during an event in a Mantis sector. When you attack and defeat it, you will be rewarded with 10 fuel, 15 missiles, 15 drone parts, a nice weapon (like a Halbert Beam or a Burst Laser MII) and the possibility to send the Mantis fleet it was leading (they listen to you because you are a great warrior or something like that) to attack the Rebel fleet, which makes the Rebels stand still for 4 or 5 jumps. You should also get a score boost.
The ship could be like this: looking like a Mantis Bomber mixed with the Mantis Cruiser, crewed by 12 Mantis with lvl 2 fighting skill, having a 4 person teleporter, 2 heavy lasers MII, 2 Leto's, 3 shields (6 bars), nice evade and one weapon room. It should have no medbay, no drones, no cloak and no AI. Because of the high rewards it should be a little rare to encounter the Mantis flagship; about 15% in Mantis controlled sectors, 25% in the Mantis homeworlds and maybe 5% in the Engi sectors (because the Mantis are invading them).
Thanks for reading through all this
