Mepersoners Stats: Statgains, Swimgains, Lifespans

Monster Rancher Metropolis: Monster Rancher 2 Archive (PSOne): FAQ: The Most Important Game Data: Mepersoners Stats: Statgains, Swimgains, Lifespans
By mepersoner on Monday, April 30, 2001 - 05:02 pm:

I'll be re-posting the stat gains of every monster after calculating them myself. It'll be on a 1-5 scale.
5= 20 on a HD, 14 or 15 on LD
4= 19 or 20 on HD, 11-14 on LD
3= 14-17 on HD, 8-11 on LD
2= 11-14 on HD, 6-9 on LD
1= 6-10 on HD, 4-7 on LD

PAL players, please note that there is no 'Swim Bug' in your game, so ignore the swimgain number.

Second Prime has the same numbers as prime, only the gain is -1. So a 4 on a LD is 10 - 13 instead of 11 - 14.

The phase right before prime and right after prime are value -1. So a 5 in power would become a 4 in power. I believe the phases right before and right after those phases are value-1 then gain -1.

I don't know the ranges for the first two and last two phases or when a stat hits a value of 0.

Complete potential of every monster
Because of the swim drill bug I did some extra work on the defense.
The best monster is based on stats, lifespan, lifestages (longer prime better), guts, and my personal opinion. Worst is based on the same thing.

pixie/naga233432 (2)17/17380 weeks

best pixie: (pixie/plant) highest stat gains of a pixie when using swim, second highest lifespan, and super fast guts make it in my opinion the best.
worst pixie:(pixie/monol) Although when using it's best stat gains it is stronger than the pixie mock it's guts are probably a bit slower and it's lifespan is worse by almost 2 years.

dragon/joker345423 (3)21/21350 weeks
dragon/monol344324 (3)20/19350 weeks

best dragon: dragon/tiger with good guts for a dragon and the highest stat gains of all the dragons, this monster takes the cake, even if it doesn't look all that great.
worst dragon: dragon/beaclon well it is the worst stat gaining and its lifespan isn't all that great, plus unlike the dragon/pixie, it doesn't get a great booste in guts.

best centaur: It's really close here, it could be the pure because it's good in most ways, the /durahan because of the lifespan or maybe even the /pixie because of the guts.
worst centaur: the centaur/barjarl has lower stat gains and doesn't have enough extra lifespan to make up for it.

best beaclon: beaclon/ducken, the ducklon, best stat gains and the normal beaclon lifespan with some nice guts to back up all that power.
worst beaclon: it may have better guts but the beaclon/tiger is really average with no strong points and a weak point, at least with the pure you know what to focus on.

Best: Even thought the zuum/dragon has the highest stat gains it lacks with less lifespan and slow guts, I'd go with the zuum/hare for equal stat gains, better guts, and more lifespan.
Worst: Zuum/monol, slower guts, less stat gains, less lifespan.

Best: Tiger/plant, equal stat gains at its best and almost an extra year and a half of lifespan, better guts too.
Worst: Tiger/monol, not horrible stat wise, but low lifespan and slows down the guts.

This is the first part of stat gains of every monster, there will be 1-3 more posts for the rest of the monsters.

Best: Although hampered by lifespan and guts I'd go with the hopper/dragon. It's a great attacker and not really all that bad at anything.
Worst: Hopper/jill, not to great of stat gains, slows the guts, just for looks.

hare/naga351342 (3)19/18380 weeks

Best hare: hare/tiger (THE ALL FAMOUS PULSAR) It has the best stat gains, good guts, and an average hare lifespan.
Worst hare: hare/zuum, why you ask, it really is just a weaker hare, a bit more defense, the fairy hare doesn't have quite the weak points (the low intelligence of the hare/zuum cannot be fixed by a 2 in the HD)and has better guts, the hare/monol just doesn't have any weakpoints in general.

Best Kato: kato/mocchi, it just is horribly horribly ugly, personally I'd rather train the kato/tiger just because it looks cooler.
Worst Kato: kato/gali, it just has shorter lifespan by 80 weeks, with equal stat gains. Still pretty good.

Best Suezo: Suezo/pixie, it just has faster guts than the suezo/tiger
Worst Suezo: suezo/naga worst stat gains and shortest lifespan

I also have to have some of the previous stat gains fixed because galis only have a 3 in power, not a 4.

Best Jill: This one I actually have think about... I really think it should go to the jill/kato, but the jill/suezo is better.... I just don't know...
Worst Jill: Jill/Pixie, takes a hit to lifespan and a hard hit to stats... just not good

Best Mocchi: Mocchi/Kato... I'm sure everyone will disagree, but the lifetype and lifespan just make it a better monster than the rest, the pure and /dragon come real close though.
Worst Mocchi: Mocchi/Pixie No need for explanation... look.

Best Joker: Joker/Tiger, good guts, stat gains, better lifespan, but make sure it comes out at least neutral natured... don't want it on the good side at all.
Worst Joker: Joker/Bajarl... just takes from the stat gains... doesn't add anything, the /golem adds power and defense and a nice long prime which the joker needs.

Best: With Jells ALMOST any Jell will do, just depends on what you're looking for.
Worst: Stay away from the Jell/Monol, it drops lifespan and skill without adding a thing.

Best: Ducken/Ducken Althought outdone by the /suezo in lifespan duckens are the type of monster that operate better with faster guts, the suezo would slow 'em down. Plus the ducken has a better life type in my opinion.
Worst: Ducken/Golem It doesn't have quite the stat gains of the others, BUT I do recommend this monster, even if it is the worst Ducken.

Best: Plant/Worm, the plant needs that extra power, plus it has a better lifetype that more than makes up for the loss in lifespan. It also makes it easier to paradoxine/troron it.
Worst: Plant/Pixie Ech... takes away lifespan and has horrible horrible stat gains.
