Review time once more!
Leaftooth (Weird name...) VS Sapphire.
Veeery short fight, but that's not necessarily a bad thing. I would imagine wyverns like Rathalos and Rathian having very quick but bloody fights with each other, which you two seemed to portray nicely. G4E, I agree with IK, you weren't aggressive enough. It is difficult to balance aggression, though. Also, threatening to eat Leaftooth's young was a bad move. Mothers of almost the entire animal kingdom actually become far more dangerous when their young are in danger, even in humans.
As for you, IK, its mostly a wording issue, in my opinion. You don't need to explain the motivations of performing an attack (As usually not explaining allows for the element of surprise), but it is good that you are very descriptive in your attacks, where they are aimed at/hit, etc.
And a piece of advice for both: The banter between the two was unnecessary. I know it was meant to be taunting from one to another, but really, motivations don't need to be explained in depth here.
Lord Ghidorah VS Megapede
A very creative fight, I must say, if not really unfair
Lord Ghidorah is a powerhouse, while Megapede is more of a skirmisher. Both seemed intent on fighting on their terms, rather then their opponent's, with the shielding and the burrowing. Though I must say DM, though it was obvious Megapede wanted LG to land, the act of continually popping up and attacking/screeching was a very creative way of luring him in. I actually think you portrayed Megapede pretty well, making sure to keep him out of direct combat. The tactic would've worked, if LG didn't have wings
As for LG, I think he was used quite well also. He has an annoying habit of countering any sort of trap, so really the only issue here was just a bad pairing of characters, in terms of fairness. Though, Megapede's best bet was probably to stay in close combat as long as he could (Without charging into the open, as I said earlier). LG seems more powerful when at ranged.
Pred-1 VS Tyrant Xeno
Difficult to brand this fight as good or bad, as its not so black and white. Descriptiveness? Check. Creative attacks? Check. Understanding of physics? ...Not so much.
DM, you must understand that Pred-1 is a 150 THOUSAND ton mech. No matter how strong, agile, or fast he is, a 150,000 ton mech will not be able to pole vault, front flip, or do anything of the sort. Also, you don't seem to take acid very seriously. Yes, shaking off the excess acid would mean less damage, but think about this: When you run your hand under a stream of water, and then flick your wrist to get the excess water off, your hand is still wet. That means that the acid would still be on Pred-1, and would still eat away at the metal, although at a much slower pace. Considering IK was pretty much spamming the acid, though, I'd say Pred-1 would have some seriously degraded armor.
As for you IK, I agree with DM, you basically tried to use a melee specialist character at ranged, which resulted badly. Although attacking Pred-1 at close range with his spear already out is unwise, at the beginning, when he had only the wrist blades, the Tyrant would've outmatched him in close combat. While Pred-1 has his wrist blades, his spear wouldn't be much use if you keep the Tyrant in constant close range, not giving him time to pull it out. The Tyrant has its claws, its inner jaws, its tail blade, and its acid, which would be much more effective at point-blank. This is a superior melee arsenal to the wrist blades, but you lost your chance after he drew the spear.
