Shichibi's Abilities

While romping on the site, I came across the Biju info page, and I thought to myself: why is the Shichibi the only one with abilities yet unknown. So, I decided to make suggestions on the matter. If the reason its abilities are unknown are for other reasons, then it's alright, but if ideas are needed...

The Shichibi, as we can all see, is reminiscent of a Rhinoceros beetle, which is famed for being the world's strongest creature (in relation to its size), being able to carry up to 850 times its weight (hard to believe). It is also common to relate the Japanese horned beetle to lightning, as its horn looks a little like a lightning rod (does it really?).

From the above research, I'll suggest crazily enhanced strength, as well as being able to create a chitinous armor which can generate lightning on its surface.

I'm a spaz; don't mind the too many words.

By the way the shichibi has unknown abilities because we let the jinchurikki user stat their own abilities but your idea seems to work fine.
