Ships/pilots are still faction specific.

TLT + Ruthlessness is a good one.

EDIT: Also Outer Rim Smuggler + Darth Vader, and for that matter, YV-666 + Darth Vader. Basically, expanding Darth Vader's firing arc is a Bad Thing.

EDIT EDIT: Miranda Doni + Gonk.

EDIT^3: 4-LOM + Mara Jade. I'll stop now.

*missed the OP

Ruthlessness on Dengar with R5-P8 seems.... Like a lot of damage to ships you aren't shooting.

Integrated astromech on corran is a fresh batch of insanity.

C3PO and R2 on a YV

Kyle Katarn on a Bossk crew, k4 YV

If Blount starts displaying Ruthlessness anyone near his target needs to start looking out.

ACD on any illicit cloaking device scum

Dengar on Whisper

VCX-100 (Ghost) with Advanced Targeting Computer.

Miranda Doni Darth Vader TLT Proton Bomb seems good

Oicunn Zeb Dengar seems good
Garven EPT Bot Body Guard + Biggs EPT bot VI

Lando and Palpatine, Kanan Jarrus on any crew imperial ship (Fel has green everything!) R2-d2 crew on Decimator plus Ysanne, quite a few broken combos.

Boba Fett is the Emperor's New Best Friend & they ride around in a Decimator and dispense Justice. ...PARTY STYLE!!!

C3PO and R2 on a YV

Kyle Katarn on a Bossk crew, k4 YV

Don't forget gonk droid on the threepio artoo YV!

Still waiting for B-wings to get astromechs so I can do to a green 2-flip. Wrong discussion though.

Ruthless and Ten Numb

Chewbacca in a Phantom isn't nuts, but it gives you good bang for your buck.

6HP and ignore a bad crit? Yes, plz.

Biggs with R2-F2

Green squad with Bodyguard

Four agility ship that you must attack.

Also:

Phantoms with Chewbacca crew, or Han Solo crew to keep their focus tokens and spend their FCS instead. Lando also. Let's just say most Rebel crew would be good on a phantom.

Zuckuss and Hera crew on a VCX-100.

R2D2 + Gonk on Dengar + Punishing One.

Unhinged Astromechs + T70s.

Zeb on oicunn would be pretty nice.

Hera and outlaw tech. You want to do red maneuvers to get your free focus.

Bossk crew on Keyan. you even get to keep your focus for defense. Or partner with Jan on another ship and focus to evade via Jan, then miss to activate Bossk to get stress, focus, TL.

Vader with Attani Mind-Link.

Rexlar Brath with Esage.

Rebel Captive on Eaden Vrill.

Emon with Sabine crew.

Dengar on Whisper is a little terrifying, given it frees the system slot up for entirely different shenanigans.

TLT + Ruthlessness on Kavil is always going to result in a little, uh, fun.

Boba Fett + Vader + R2D2 on a Decimator. Hand out a crit for one damage apiece. Fly with a Palpshuttle and you can't even botch the self-crippling roll.

Boba Fett + Vader + R2D2 on Bossk: Same trick as above, but now you're trading health 1:1 without even hitting the target. Once R2D2 kicks in, you're pumping more damage than you're taking. Take HotShot Blaster if you want to have rear arc coverage, and giggle.

YV-666 flying Hera, Outlaw Techs: Park forever, get focus tokens for it. Goes great with Chopper or Bossk, too. (Shuttles can do the same, though other than 'whiting' their hard turns I don't know if they profit as much.)

Kenkirk of annoying

C3-PO

Jan Orrs

Ysanne Isaard

3 evades each turn...

R2 Astromech on JM5K. Why yes I would like green sloops.

Darth Vader on Miranda. Shield Regen plus guaranteed damage.
