Captain Cold in Flashpoint Roblox gives you a custom badge called Captain Zero when you defeat him, and videos about the boss also mention rewards tied to XP, cash, and suits from the Flashpoint progression system.

Quick Scoop

The clearest boss-specific reward shown in the available source is the badge, Captain Zero.

That same source also says the game’s Flashpoint progression can award 250,000 XP and 100,000 cash on the regular side, with higher totals on premium completion, but that looks like tier/progression rewards rather than only the boss drop.

What people usually mean

If you’re asking “what do you get for beating Captain Cold?”, the safest answer is:

  • Captain Zero badge.
  • Possible progression rewards like XP and cash through the event/tier system.
  • Potential suit unlock progress connected to Flashpoint tiers.

TL;DR

Beat Captain Cold, and the confirmed direct reward is the Captain Zero badge.
