Horobi's upgrade is actually using that sword he always carries!

Personally, I wouldn't mind if he kept being able to fight evenly with the others despite never getting an upgrade, since it's consistent with how he's been portrayed so far (remember, when the ForceRiser debuted, it was seriously overpowered compared to what the other Riders had at the time) and it would make him menacing in a way that's good for villains. Especially if he made some comment about skill making it not matter if his opponent had a technically stronger form. "Even in battle, you rely on tools to save you. But tools won't help against the superior learning abilities of a HumaGear." Something like that.
