Or so I would hope, with this:

Biggs + R7

Cracken

This can work with a few different things like Squad Leader or Lando, but I think the time that Cracken gives the free action makes this the perfect time for Biggs to take the TL to potentially use defensively via R7.

HOW YOU MAEK BIGGS LIVE?!

Too situational. You may have a target lock on someone not attacking you.

Biggs and R2-F2

Cracken

Garvin

Once rebel aces comes out you could pair that with jan and nien crew on lando and maybe give Biggs a SD. Keep at r3 as much as possible and you should at the very least give your opponent a massive headache. If my math is right( big if) then that plus squad leader on the cracken and ptl on lando makes 100! XD

EDIT: sorry for leaving you out, Garven...

I'm thinking that one of the crew members shown in Rebel Aces has promise:

Jan Ors (2) Whenever a friendly pilot in Range (I can't remember, but I think it's 1-3) performs a Focus action or acquires a Focus token, you may assign them an Evade token instead.

With her in a fleet and an allied ship that can pass Biggs a Focus Token, he's suddenly filled with the mighty "Negate 1 damage in every turn you are attacked" that is the Evade Token, alongside the traditionally good defensive focus to which he is accustomed.

Heck, at that point a regenerative Astromech might be viable on him. "Negate 1 damage in every turn you are attacked, and Negate 1 damage every turn you survive" is a fairly potent combo.

Alternatively, fly Biggs independently from the main formation, and give him a regenerative astromech. Fly in at full HP, tank some fire, run away to lick your wounds, repeat.

You're throwing one of your ships out of combat for a few rounds in favor of fully negating all of the damage he took while he was in combat.

Here are 2 of the best I can come up with to make him live!

Biggs, R2-F2, Stealth Device

Cracken, DTF

Kyle Katarn, Ion Turret, Jan Ors

Rookie

Biggs now has between 4-6 Evade dice (until he gets hit, then 3-5) with Focus and Evade.

Or a more traditional:

Biggs, Shield, R2-D2, Stealth Device

Cracken, DTF

Kyle Katarn, Ion Turret, Jan Ors

Green Sqn, DTF

Less green dice but increased health/regenerating shields and still has a Focus and Evade.

Too situational. You may have a target lock on someone not attacking you.

Biggs and R2-F2

Cracken

Garvin

If Cracken is giving you the Target Lock after his PS8 attack early in combat then you will know who is in range already and who will be forced to attack Biggs. The only part that seems situational is that it is once per round, but so is using a Focus token under normal circumstances.

HSF

Biggs

Cracken

Loses 1 red dice for extended protection from biggs for Han. Han might make up that damage...

interesting that all the components for HSF with biggs = 100 exactly.
