Could be. If they do go with double entendre it could also mean "fighting rhino" which is written as 鬪犀 .

Japan loves making puns~

So "Mounted Beast King?"

And the combo between the 3 Robos is Wild Mounted King?

Or equipped. I use mounted because cube rhinos literally mounts the cubes.

A crocodile, rhino, and wolf? Is this Gaoranger? :lol

Well you could call it Gaoranger 2.0 if you like. Both Sentai are about animals.

Do you think Misao will resent most of Zyuohgers because they are indirectly responsible of him becoming a Zyuohger.

Just says if Yamato didn't bring 4 Zyumans to his world, Misao wouldn't have abducted by Ginis and wouldn't become Zyuoh TheWorld.

He will still help them but he will distant from Zyuohgers because they were blamed to his transformation of Zyuoh TheWorld.

Once he's no longer brainwashed, Do you think he will be anti-social to Zyuohgers because His color is BLACK. Most of Black Rangers are usually NOT a goody two shoes guy and tend to be the ANTI-HERO.

Not really, but those are very specific animals for the sixth ranger.

Correction. One famous black is associated with not being a goody two shoes, and one extra hero that happens to be black is an anti-hero.
Most Black rangers tend to just be mildly more aggressive (GoseiBlack, BoukenBlack) or loners (Ninja Black, KyoryuBlack), but they're all still just as heroic as their partners.

Wanna know something funny? Red (TimeRed (Original), KabutoRaiger, TimeFire) is the most consistent anti-hero color for Sentai.

GaoSilver had a hammerhead shark though. The rhino wasn't his.
