In an episode of Lois and Clark, Lex Luthor creates a boxer that he believes can take on Superman. The boxer delivers a flurry of punches that stagger Superman. For a moment it looks like Superman is actually on the ropes, but then he simply flicks the boxer in the forehead and knocks him out.
Most space-faring vessels in the Star Trek universe fall under this category if something ever happens to their Deflector Shields. (It happens more often than you'd imagine.) Watch the Federation's Flagship get roflstomped by an obsolete warbird thanks to shield sabotage here.

- In Star Trek: Deep Space Nine, Jem'Hadar Fighters are pretty much this. They're able to deal heavy damage, at least early on, with only a few bursts of their phased polaron beams, but a few phaser cannon shots or a single torpedo are enough to either cripple or destroy them. This is deliberate on part of the Dominion, with the Fighters being cheap but deadly throwaway ships with minimal and expendable crew, and no features that aren't essential to combat.
