Thundercats #23

Marvel's "Special High Voltage Issue!" banner sets the tone perfectly for this underwater nightmare — Lion-O is shown submerged and in serious trouble, fighting off a massive, razor-toothed creature while still gripping his sword, with the cover copy cheekily warning he could be drowned, electrocuted, or eaten alive. It's a genuinely tense image, capturing the ThunderCats hero at his most vulnerable against an enormous aquatic predator. With a story titled "Dr. Dometone" and a creative team including Tom DeFalco, William Overgard, and artist Dwayne Turner, this 1988 entry promises high-stakes adventure beneath the waves.
