Anime is notorious for its nonsensically strong characters. Even with an overwhelming amount of supremely strong characters, not many can truly call themselves invincible. Naturally, the pool is even smaller for villains. Regardless, some villains are far superior as compared to their virtuous counterparts.
Anime villains need to be at least as strong as their hero counterparts, but some of them manage to outwit or overpower protagonists time and time again. Be it their undeniable guile, exceptional strength, or the author simply hasn't gotten around to their defeat, some anime villains remain unbeatable.
10 Don't Be Fooled By Kyubey's Cuteness (Puella Magi Madoka Magica)

8 Yujiro Hanma Has Superhuman Strength (Baki)
Just by looking at Yujiro's physique, it shouldn't come as a surprise that he remains the strongest and most unbeatable villain in the Baki universe — perhaps in all of anime. His strength and endurance challenge the very idea of human capacities, surpassing any limitations set by his predecessors.
