Drive Knight is the S-Class Rank 9 hero in "One Punch Man". Drive Knight is a black-haired man wearing a white mask with a single red shinning eye and his armor is similar to black knights armor. He is first seen in Chapter 29 in the Manga and Episode 10 in the anime.
He is one of the powerful characters in "One Punch Man" as Being an S-Class hero is a proof. Drive Knight has an Immense Strength as he was able to rip off the head of a Tiger level Mysterious Being with his bare hands. Drive Knight also has an immense speed as he was able to quickly decapitate two Tiger Level Mysterious being before any of them could figure out what was happening.
Drive Knight can use Tactical Transformation through a shape changing box that appears to have various cybernetic parts and He can use it in combat transforming it into various weapons or tools to battle his opponents. Drive Knight manage can use Centaur form where Drive knight fuse with his shape changing box and transform his lower body into a mechanical horse that give him speed and leg strength. Drive Knight also uses the box to fuse it into his right arm into an electric imbued sword he called Silver.
Silver is a powerful sword as it was able to slice through multiple mysterious beings in one strike. Drive Knight is still a mysterious hero as it is not known if he's a cyborg or if he is just wearing an armor. Another thing is that we need to wait what Drive Knight means when he told Genos not to trust Metal Knight, an S-Class Rank 6 hero.
There could be a possibility that Metal Knight will be a villain in "One Punch Man" or it is because Metal Knight loves to collect technologies or various stuff that it could mean that he might stole the technology or cybernetic parts that is installed with Genos. This could be a reason why he wants Genos to not trust Metal Knight.
There's a lot of things that could happen in "One Punch Man" Season 2. Lets wait and find out.
