Well I can picture the scenario like this:

• 2nd round: Gira and Racules duel again. Only this time, he has the combined power of Spider Kumonos at his side. Racules gets himself sealed in an iron mask like Jeramie?s locked up.
• Third round: Racules is somehow broken out of his prison and the brothers Duke it out again. Gira then obtains the power of the gold ranger.
• Final round: duel to the death

With modern Sentai, I doubt Gira actually kills Racules. If he dies, either the true big bad of the series takes him out as getting rid of competition, Worf effect as TVtropes would put it, or he pulls a heroic sacrifice for whatever reason

I doubt it. It just probably won't be as proportionally accurate, like every Sentai mecha suit ever.

Only last year, we had Sonoi killing Tarou, Tarou killing Sonoi and Sonoi killing Tarou again. I see no reason why Gira killing Racles couldn't happen.

Yeah and I?d love to see Racules have himself locked up in an iron mask. Maybe Gira will Racules until nearing the end of the show.

Those were just temporary though, and it was Inoue. Pretty sure Toei let's him do whatever the hell he wants at this point

To be fair it's been confirmed that the temporary part was not planned, though the way Racles has been handled alongside the fact that Sentai doesn't really kill off rangers much to begin with suggests Racles would likely be redeemed if anything

Yeah no if there is no twist about "Racles not being Gira's brother" or something you can forget the idea of Gira killing Racles. I don't think "killing a family member" is on Toei's program, whatever the reason.

I agree it feels like the way he is written he'll be redeemed at some point and if he dies it will be some kind of sacrifice or something, nothing more.

I doubt Toei are totally against depictions of killing family, as there have been examples of heroic patricide as recent as Zenkaiger and Revice.

I'm inclined to believe that Racles' goal to conquer Terra is in service of some greater purpose and he's not entirely as he appears. However, I also don't think his redemption and Gira killing him are mutually exclusive, as he might offer his life to Gira in battle, as penance so he can reclaim his honor.

I could argue Revice is a bit of a special case because the center theme of the show is precisely family, but, my bad, that's actually quite fair.
Patricide especially could almost be in a different league haha (KR and Father is almost always ending badly)

But I still think something like Gira killing Racles is almost impossible so far considering what the show showed us (tone/atmosphere)
