Endosym in Iron Man Reimagined
The speed king inside the nanotech bundle. Comic-book slime, 630+ velocity, same receipt as Mark 85.
Endosym is the speed cousin inside the Advanced Nanotech bundle at 399 Robux. Public comments on the every-suit climb corrected Clickster when he thought Endosym was free - it is pass-gated alongside Mark 85. The comic-book origin is Model 50: a liquid smart-metal that hardens on psionic connection, borrowing cellular building blocks from symbiote biology. The Roblox version inherits that aesthetic and adds the velocity the comics promise. The embedded video in the middle of this page is the clearest public showcase of the suit in motion.
Speed over repair
Endosym and Mark 85 share the same nanotech receipt, but Endosym is the speed row. Community tests log 630+ studs per second with boost crossing 1,000. That is the number the suit tour throws because it is the number the chassis prints. Mark 85 matches that band but trades some velocity for the self-repair crawl that keeps you in a fight. If Star Boost is the free orbit ticket and Helios is the group orbit ticket, Endosym is the paid speed orbit chassis.
The repair verb still exists - T or click broken plates moves nanobots - but the fantasy is thrust, not patience. Do not buy Endosym expecting Mark 85 with a paint job. Expect the same nanobot system with a different flight profile.
Versus Mark 85
Both are on the 399 receipt. Mark 85 is the recognizable MCU endgame plate. Endosym is the comic-book speed freak. Spanish recaps call Endosym the better buy for players who want orbit without recasting, while Mark 85 wins the recognizable look argument. The tier list parks both at S for the nanotech cluster because the receipt is the same, not because the kits are identical.
Space capability
Endosym makes the Venus commute without Star Boost. It is not the sentry cheese that community route credits to Oo Animations - that trick still lives on Mark 39 in the how to go to space guide. Endosym is the fast lane, not the route. Planet names belong on the planets map once you hold the green HUD.
How to call it
Own the nanotech pass, press Q, scroll past free chassis and War Machine, click Endosym. The Q menu treats it as a separate row from Mark 85 even though both sit on the same receipt. Destroy leftovers with X if a previous shell is stuck. There is no code for this suit. There is no GUI Beta loader that grants it. Both are script safety issues if you see them marketed as free alternatives.
The suit has been on the store since April 2024 alongside Mark 85. It will still be there after you finish a week of Star Boost commutes. Buy the speed row only after Getting Started and how to fly no longer feel like a brick. Hover first, then buy the velocity.

No. Public comments confirmed it is gated to the 399 Robux nanotech pass. Check your Q menu before budgeting.

T or click the broken plate to move nanobots from a healthy limb. Same system as Mark 85.
Does Endosym have custom weapons?
Yes. The nanotech bundle includes shield, blade, and battery rams. See the nanotech guide.
