when was the first kolossos sneak peak shown for td

The first public sneak peek I found for Kolossos in TD appears to be a YouTube upload from January 14, 2026 titled “KOLOSSOS OM SKIN SNEAK PEAKS | Sonic.EXE: The Disaster Rexecution”

. A later YouTube playlist page also groups it under “TD REXECUTION,” which supports that this was part of the Rexecution-era teaser rollout

Quick scoop

If you meant the earliest visible teaser/public preview , January 14, 2026 is the clearest date I found. Another result from late February 2025 mentions Kolossos sneak peek updates, but it reads more like a repost or reference than the original first reveal.

Why this looks like the first

• The January 14 video is explicitly framed as a “sneak peak” for Kolossos.

• The playlist entry shows it as part of the TD Rexecution teaser set, which fits a first-preview context.

• I did not find a clearly earlier source that unambiguously shows Kolossos himself being previewed first.

TL;DR

The best-supported answer is January 14, 2026 for the first public Kolossos sneak peek in TD.
