Weapons? Let’s see… chrome trim package, big ass spoiler, racing stripes, a painting of a samurai on the hood uttering a fierce battle cry… oh and a .22 at road level to blow out other cars’ tires.
[sub]I feel compelled to point out that I would never actually be seen driving such an ugly vehicle. I have unfortunately witnessed a Civic with purple neon lights, and it was oddly mesmerizing yet repulsive.[/sub]
Ok, here’s my real choice. Invulnerable is boring, I’ll go for interesting instead.
Start with the SDF-3 and its full complement of Alpha/Beta Veritechs, because Robotech rules. Add extra hangar space and throw in a couple groups of TIE Defenders and Missile Boats, and the Acolyte fighters, Multi-Beam Frigates, and Leech weapons from Homeworld: Cataclysm. The Leeches sneak onto an enemy ship’s hull and vent its energy away into space.
Use Borg implants on the crew for instant communication, but allow for individuality in case someone has good ideas.
Give it the Langston Field from Niven and Pournelle’s The Mote In God’s Eye, with Motie modifications, but keep the point-defense shields also. The Langston Field absorbs the energy of attacks, changing color in the process. It starts out black, so it doubles as a cloaking device. Use Motie Engineers and Watchmakers for repairs, but sterilize them so they don’t breed and take over the ship. Turn down the individuality knob on their Borg implants.
Install the Dr. Device from Card’s Ender’s Game. This weapon disrupts molecular bonds and chain reacts with any matter close enough, but has a slow recharge rate. In the book there was no defense against it, but in this composite universe there might be. On second thought, it sounds a lot like the Reflex Cannon. Hmmm…
Use Star Wars Assault Transports (from the X-Wing computer games) for boarding parties, but instead of Stormtroopers use Warhammer 40K Space Marines. Transporter beams are cheesy.
Broadcast Minmei’s inane musical stylings on all channels, to stun the enemy crews into unconsciousness.
Modify the main engines so they have a purple neon glow, just to get on Mnementh’s nerves. Hyperspace away when he comes after me.
