Following up on this ruling: "Based off the I Still Function! Ruling, would I be able to transform Razorclaw to bot mode, then combine into Predaking but retain his flip ability to attack untapped characters since he's part of the Combiner? Yes." Does this mean that if I flip Rampage into bot-mode and combine into Predaking that turn, will Predaking carry over the ability to repair 1 damage to all my Predacons if Predaking KO's an enemy character?

Rampage’s ability has not triggered yet and would not carry over as it does not specify the duration of “this turn” like Razorclaw’s ability does.

If my Predaking attacks with 5 weapons and a Spare Parts, and my opponent reveals a Sabotage Armaments Secret Action, what happens? Does the Sabotage Armaments scrap Spare Parts only or does it scrap only 4 of the Weapons and Spare Parts?

In this scenario, you could use Spare Parts to save one Weapon of your choice.

What exactly happens when I attack using... 1. Dreadwing with 2 Anticipation Engines and 2 Metal Detectors? 2. Predaking with 3 Anticipation Engines?

With multiple Anticipation Engines and/or Metal Detectors, you handle the abilities one at a time. If you have an Anticipation Engine and a Metal Detector, you must specify which one you are using before revealing the card. If the card you reveal doesn’t match the type of card you’re looking for, it just stays on top of your deck. The next ability will reveal the same card, so choose wisely.

If Dreadwing is equipped with Combat Training and 2 weapons and/or armors, does Combat Training give Dreadwing bold/tough 2 since he has 2 weapons/armors? Same question can be asked for Predaking; Does he get Bold 5 if he has 5 weapons and combat training?

No. A single Combat Training gives Bold/Tough 1 at most.

Does Predaking just have 5 weapon slots, or 5 weapon slots and the usual 1 utility and armor slot?

All characters will have the default slots unless otherwise specified. He has 5 weapon, 1 armor, 1 utility.

Same for Predaking? So he could be combined with up to 3 Laser Cutlasses?

Yes.
