And it gained popularity among paleontologists to the point it's the official name for the tail weapons of Stegosaurs and Ankylosaurs.

Thagomizer. That's a fun word to say. Tha-go-mi-zer.

Oh. That was the point of adding the spikes to the pommel of the sword...

would work better as a stegosaurus mased weapon than the Muramasa Blaster.

Sounds like a sentai henshin device

I wouldn't mind that, either.

would it be weird to have the belt make chants kinda like OOO's or Jago's theme from Killer Instinct?

Sure but it would be better if we straighten it a little and make the spikes bigger just to make the combining gimmick easier

I was imagining the henshin/standby jingle having lots of bassy drums and chants to it. Although, would we even need to speculate on the sound design, given that this Rider would basically exist in visuals and text? I dunno.

Yuu! You're talented. You should do some kind of sketch up of this combined weapon idea to give the others some kind of visual.
