Satandelos is a kaiju-like monster appearing in Ultraman Trigger. It serves as one of the series' hostile giant entities, threatening cities and forcing Ultraman Trigger and the GUTS-Select team to respond. The creature is portrayed as a dangerous, powerful adversary rather than a recurring character with a personal identity. Its role in the series is to create a large-scale combat challenge and highlight Trigger’s ability to protect humanity from monstrous attacks.
