Speed Force connection/Meta-human physiology: It remains unclear on whether Earth Nineteen had a Particle Accelerator explosion or how he gained his abilities, but what's conspicuous is that with his apparent display of super speed, He has somewhat of a connection to the Speed Force that has possibly granted him access to the multiverse.
Superhuman speed: "Accelerated Man" has displayed his ability of superhuman speeds. The full limit of his capabilities is currently unknown.
Interdimensional travel: This ability becomes a relatively useful ability among speed conduits, however it remains unclear if he was able to pass the minimum threshold of speed required to create a breach allowing him to temporarily stabilize the inter-dimensional "corridors" that linked any one breach on Earth Nineteen with a corresponding breach on Earth Two, or if it was created from an external source.
Electrokinesis: Accelerated Man emits bolts of purple lightning when using super speed. It is unclear whether this is due to a connection to the Speed Force, as is the case with other known speedsters.
