Steel Fighters parts
This is a parts-system reference, not a complete item or drop-rate catalogue. Gameplay documents six build slots and an Index with Industry, Extreme, Arena, Elite, Epic and Traits tabs. Current drop rates and every family variant have not been captured.
Evidence: LuvYaCoffee's Index at 10:00 and Ricoko's reforge panel at 0:40 are external gameplay references. The diagrams on this page explain those systems; they are not our own gameplay screenshots or a current inventory scan.
Six slots and the collection Index
A build uses a head, torso, left arm, right arm, left leg and right leg. The recorded Industry frame shows Buddy 6/12, Anvil 1/8, Drill 3/10 and Crane 2/18. Those are collection counters in one account, not drop probabilities or the number of equipped slots.
The Index is the place to inspect your missing entries. An observed tab or family name does not establish that every part of that type has been documented here. Colour alone is insufficient for assigning a current rarity or drop rate.
Where to check for parts
The official description advertises mixing parts from 100+ robots and free parts for favouriting. Gameplay shows a parts lever. Sportskeeda reports that Update 1 adds parts, lever-tier settings and Index completion rewards; the exact reward size is not established here.
The earlier pack price table came from one secondary database and had not been checked against purchase buttons. It has been removed. Check the full displayed price and quantity in the client; no pack value recommendation is made here.
Reforge changes a part bonus
The recorded reforge panel shows a random range from -20% to +20%, with a Golden Hammer option showing +20%. A random roll can reduce the bonus. Costs and eligibility may depend on the part; this site has not tested a universal price or result.
Reforge is distinct from assembling a matching-family set. The reported Perfect bonus is +10% for matching parts; the exact stacking rules and any equal-level requirement still need in-game confirmation.
Fusion and unlock costs
Ricoko footage at 0:18 documents the Fusion Lab. The research records three robots used for a stronger result and a 10K Cash unlock sign, plus a 100K Cash sign for the reforger.
These are observations from an account in October 24 footage, not guaranteed current prices or a complete fusion recipe. Check the confirmation screen, required robots and resulting stats before using a system that consumes resources.

Questions
Where is the complete parts list?
This site has not captured a complete Index. The client Index is the current reference for missing entries; no full catalogue is claimed here.
What are the rarest parts?
No verified drop-rate table is available here. An Epic tab or purple colour does not by itself establish a probability or a strongest-part ranking.
Does Perfect always beat mixed parts?
No. The reported set bonus does not remove differences in base stats, levels and reforge rolls.
