I found a source saying Ichiko (True Kai) in Anime Last Stand came from evolving Ichiko (Fullbring Kai) , and the video snippet mentions that the game added three new evolutions in that update: Nameless, Dark, Soul, and Eternal One are listed in the footage, though that wording is a bit inconsistent.

What that likely means

  • If you mean how many evolutions Ichiko has in UD/Roblox , the safest answer from the available info is at least one evolution path for the True Kai version, because it is explicitly shown as an evolved unit.
  • If you mean how many evolution forms Ichiko has overall , the available evidence here is not enough to give a reliable exact count without risking a wrong answer.

Best estimate

  • Confirmed: 1 evolution path for Ichiko (Fullbring Kai) to Ichiko (True Kai).
  • Unconfirmed from these sources: the full total number of Ichiko evolution variants.

TL;DR

The clearest verified answer is 1 confirmed evolution path for Ichiko in the sources I found.
