As in, the villains who aren't speedsters or super smart, but their overwhelming physicality makes them a threat. Some may have other powers but the physicality still remains a bigbdead deal Here's who I think fit:
* Grodd (yes his telepathy is the main problem, but his strength and toughness always means trouble for Barry)
* King Shark
* Atom Smasher
* Griffin Grey
Who else fits?
Grodd is a multi-level threat, being a genius who is also psionically powerful and physically powerful. He doesn't belong on a list of characters who are primarily a physical threat. He's too complete a package to be called "primarily" anything.
