B-Daman Crossfire (anime)
At the end of episode 26 in Crossfire, a rabbit B-Animal flew into this B-Daman, and the B-Daman itself started to talk.
- Lightning Rabbit is a reference to the hare from the legend of the Hare of Inaba, from which its wielder, Sumi Inaba, gets her surname.
- This is the only B-Daman besides Strike Swallow to have a "female" B-Animal.
- It is affectionately referred to as Rabbit-chan.
- This was the first B-Daman to be shown on the anime.
