I'm giving the edge to Engi- I mean the... High Octane Megazord. I just feel it would be better in this scenario, because compared to Thunder Thunder, it has a pretty significant arsenal advantage. All Qiden Shorai here has is a sword and a spear that he never used in the show. Meanwhile, Engine Soul Set has a sword, a shield, and 3 additional combinations(by the rules stated in the OP), two of which grant it ranged combat. I really feel like the Thunder Megazord is only winning based on Nostalgia-Handsomeness.

Good point, but Seriously guys, someone vote 5 more times and we can have round 3, and Im sure it will have more disscussion based on the 2 series represented there :lol

That's why I ditched my coin and went with High Octane Megazord

Gotta go with RPM. The pilots make the mech. Thunderzord is AWESOME don't get me wrong. Super cool if kind of chubby. But I still weirdly like the RPM design.

Going to go with the high octane megazord, due to the more options it had. On a side note, i never liked the thunder megazord.

And I dont see High Octane getting another 17 votes in the next 3 hours,

Final score as of this post - 30-17, Thunder Wins

So round 3 will be up shortly, will the copycat series brave the weather?
