Avengers #154 (1976) features the first appearance of Tyrak (in disguise as Triton), adding a notable Atlantean villain to Marvel continuity and tying into Sub-Mariner-related storylines. This issue continues the Bronze Age trend of expanding Marvel’s underwater and cosmic mythologies.

Written by Gerry Conway with art by George Pérez and Pablo Marcos, this issue showcases strong creative talent during a key transitional era for the Avengers. The cover, featuring multiple Avengers alongside Atlantean forces, delivers classic Bronze Age visual appeal.

This CGC 9.6 Near Mint+ copy (Off-White to White Pages) is a high-grade example with sharp presentation, vibrant colors, and excellent structural integrity—high-grade copies from this era are increasingly difficult to source.

A strong addition for Avengers collectors, Sub-Mariner fans, and Bronze Age Marvel investors seeking key first appearances in premium condition.
