jajajaj, lol about luigi...
.. it seems that
http://www.pokebeach.com/ have the translations of the pokemon related players, i will post them, but i don't know how accurate they are (still , i loled a lot with the ocelot reference XD)
Pikachu Explanation -
"Oh, how cute!"
"What is? You mean that yellow guy?"
"That's Pikachu. It's a universally popular Pokemon.
It appears cute, but you have to be careful. In the sacs in its cheeks, it stores a large amount of electricity."
It can obviously torture you over and over with electrical attacks."
"As long as he doesn't do it too often, it's probably better than Ocelot's torture."
"By the way, Snake?"
"What?"
"If you can, I'd like you to catch Pikachu for me...is that too much?"
"Give me a break. I'm not a Pokemon Trainer."
"Hmm....aw."
Jigglypuff Explanation -
"The big eyeball is walking..."
"That's Jigglypuff."
"Jigglypuff? Don't say it's a dessert." (Note: Jigglypuff's Japanese name is "Purin," a pun on "pudding.")
"Jigglypuff is a Balloon Pokemon. Since its innards are air, it's light, but the power of its "Rest" is tremendous."
"Rest..? It isn't a normal sleep is it?"
"At the very instant it goes to sleep, there's an incredible energy reaction at the center of its body."
"If you eat it, you'll probably be instantly KOed."
"It's spirited while asleep? Completely hopeless."
"The world is big. Especially this 'brawl'."
Lucario Explanation -
"You're fighting Lucario? Snake."
"Mei Ling, what is the purple flame coming out of the guy's hand?"
"That's 'wave'." (Note: In Lucario and the Mystery of Mew, "wave" was translated as "aura.")
"'Wave'?"
"Something like lifeforce. Lucario controls its own wave, and that's what is shining with power.
"Lucario increases its wave when it takes damage, becoming stronger."
"So, don't let your guard down saying, 'Since I did a lot of damage to it...'."
"You're saying, 'A cornered rat is dangerous'? ... What a nuisance."
"Oh? Even Snake uses proverbs occasionally. How surprising."
"It's thanks to you."
"When you come back, I'll teach you plenty of Chinese proverbs."
Pokemon Trainer Explanation -
"The one instructing the Pokemon from the background, he's a Pokemon Trainer?"
"That Pokemon Trainer is carrying Squirtle, Ivysaur, and Charizard."
"They're powerful Pokemon that represent the Water, Grass, and Fire type respectively."
"He prepares them to fight, then watches on. A good position, isn't it."
"You could say that. When the Pokemon fight, it's on the Pokemon Trainer's orders."
"On the battlefield, a soldier who manages field strategy and evaluates the progress of war is indespensible."
"If they maintain a good combination together, their power is probably multiplied."
"That's why we also work well together. Don't you think, Snake?"
"...All right, thanks for your help."
