Anyway, my picks are:

Silurians will fry them, of course if the Haemovores can sneak up, it might be a different story.
Judoon are just so butch – Flob, Klob, job, mob, they win
Primords monkey men made from slime will roll the Krotons
Vervoids have ultimate victory over the lizard creatures

Silurians (powerful third eye)
Krillitanes (they can fly)
Krotons (although blind, they have built-in weaponry)
Terileptils (better tactical skills)

The Haemovores will outdo the Silurians, because it’s not about weapons. In the words of an older man than I, you’ve got to have faith-a-faith-a-faith-ah. Baybeh (et cetera). And I just don’t see those Silurians summoning their wholesome beilef in science to fend off the warty wampyrs. I’m bound to be outnumbered though…

…because bout two IS about the guns, and the training, and the application. I have no bias, Jamas. I just know I’m right. Rhinos FTW.

Primords versus Krotons… tricky. Is it to be drunken monkeys overturning shopping trolley robots, or will those big big guns do their worst. I’m going to say Krotons. They may be directionally challenged, but none of them ever fell off a huge tank. Because they ARE huge tanks, and there’s the genius of it.

Terileptils versus Vervoids. Heh. Probably Terileptils – all that time down t’pits, they must be tougher than tough (but with an aesthetic in robots to simply die for!)

Primords (brute strength defeats higher IQ)
Terileptils (superior firepower and intellect)

The Judoon will beat the Krillitane no trouble at all…

Primords versus Krotons is no contest. All the Primords have to do is push the Krotons over and they’re stuffed.

And I’ll add to the consensus and nominate the Vervoids to win the last battle, thereby being eliminated…

Dammit, I think the Krotons are going to be the ultimate losers, as I see the Primords taking them.
I think the location here gives the plant people the head start, and with that, they win.
