Reverse-Flash Rings (Earth-1: Pre-Crisis)

The Reverse-Flash Rings are a series of rings that stones the Reverse-Flash Suits.

First ring
The original suit was bought back from 2151 when Eobard started to become the archenemy of The Flash.

Destruction
During the final battle against Eobard, Eddie shot himself in the chest causing his death and the timeline to change. As Eobard is a descendant of Eddie, he started to be erased out of existence and the suit followed him as well.

Spare ring
A spare ring was stored in the Time Vault and was used to access the suit by Harry to trick Grodd.

Time Remnant ring
After Eobard was erased out of existence, a Time Remnant was created to protect the timeline and he was on the hunt of the Spear of Destiny. The ring was also recreated along with Eobard's body.

Destruction
When Eobard is about to take away the Spear of Destiny, Black Flash arrived and killed Eobard, causing him to be erased out of existence again.

Flash Museum ring
After the Earth-X invasion and Barry released Eobard, he went to 2049 and was incarcerated in Iron Heights with the suit stored in the Flash Museum along with his ring. During his execution, the guard gave him the ring with the suit inside.
