Summary of the Verse

Power of the Verse
JoJo's Bizarre Adventure contains many weak characters in terms of sheer brute force with all of the high tier characters being Large Town Level (Which includes Powerful Stands, Powerful Hamon Warriors, Powerful Vampires and Pillar Men) with weaker characters ranging from Below Average Human Level to City Block Level (Fodder Vampires, Weak Hamon Users, Weaker Stands and most Stand Users). Aside from a few other characters that are City Level and even Island Level. The God Tiers of the verse are the characters that range between High Universe Level and High Multiverse Level+.

In terms of speed feats, most of the characters fall into the MFTL speed since they are comparable to Silver Chariot which moved faster than a beam of light and blocked several beams of light at the same time. Characters from Part One and early Part Two are Hypersonic by comparing to Jonathan who reacted to a high-pressure water jet.
 * Stands: From Part 3 onward every major character possess the ability to summon a being known as a Stand. Stands are the physical manifestation of the user's soul that the user fights with. Unless they are bound to a physical object (Such as a vehicle or the user themselves) these are always invisible to all Non-Stand users. Stands have a vast array of abilities such as several forms of Time Manipulation, Spatial Manipulation, Causality Manipulation, Reality Warping.
 * Stands come in various forms, Close-Range Stands which are powerful but cannot move far from its user, Long-Range Stands which are weaker but can travel further from its user, Automatic Stands which can move as far as it wants from its user and any damage that the Stand takes the user doesn't take, however, the Stands are predictable in nature, Bound Stands which are bound to physical objects which means that anyone can see and interact with them but the user can use them as an actual weapon to protect themselves and are typically bigger than other Stands, Colony Stands which are a group of small Stands that look identical which are much weaker, however, the user takes less damage when one his harmed because of the fact there are multiple Stands, these can range from six to one hundred and Sentient Stands which are Stands that the user can control but also can think for themselves and can come up with plans that the user might not have thought of while protecting.
