I was recently putting together a rhino - I couldn't make it work at size level 1 with 15 extra bio-e from feral, and taking disadvantages...so yes I'd take you up on that offer. I think I needed about an extra 50-100 bio-e to make it work. Its interesting that a game system setup for making mutant animals doesn't let you be a full everything looks nothing with all the animal attributes at size level 10. Instead I end up with mighty rhino mouse, who doesn't have full hands, speech, etc.
I thought I’d put this to the test, so I tried to make a character based on a rhino. As there is not rhino in the book, I picked a similar type of animal (I chose the buffalo). As I was creating the character, I realised that not only could I stay pretty big, but that I had a shot at staying really big using the really big and dumb and/or the big and slow options.
Buffalo SL: 19, Bio-E: 5
Size:
-2 size levels to size level 17 = 10 Bio-E.
Big and slow/dumb, and/or really big and slow/dumb, say 10 Bio-E depending on attribute rolls.
Vestigial traits:
Musk glands = 5 Bio-E
Diet: Ruminant = 5 Bio-E
So, 35 Bio-E to spend:
Human features:
Hands: Full
Biped: Full
Speech: partial
Looks: none
Cost = 25 Bio-E
Natural weapons/Powers:
Horns 2D6 (gotta have horns)
Brute strength (automatic)
Advanced vision (automatic)
Extra Spd. (making up for the Spd. penalty from being that big and from ‘big and slow’)
Cost = 10 Bio-E
So, I haven’t got a huge amount of powers, but I’m still absolutely
massive at size level 17! Giving me a total P.S. bonus of 20! And there is another 30 Bio-E’s worth of vestigial disadvantages still available to me should I wish to trade them for more powers or features. Also, I think that a rhino or buffalo character lends itself well to a partial biped character, so there is an option there for further Bio-E. If I rolled high enough for I.Q. and M.E. or P.P. and Spd., I might even be able to get more Bio-E from the really big and slow/dumb option).
For a smaller character, created without using the big and slow/dumb option, I can get the following:
Size level: 12
Human features:
Hands: Full
Biped: Full
Speech: Partial
Looks: none
Natural weapons/Powers:
Horns (2D6)
Hooved feet (3D6)
Advanced vision (automatic)
Beastly strength
Extra Spd.
Vestigial traits:
Musk glands
Diet: Ruminant
Still 6-7 ft tall, with a couple of extra powers. And, as before, another 30 Bio-E’s worth of vestigial disadvantages available for those who want to be bigger or have full speech etc. Who says you have to make characters size level 1?!
Update: I found an updated Rhino template on the boards, and gave that one a go, as that was the example animal given:
Size level: 11
Human features:
Hands: Full
Biped: Full
Speech: Full
Looks: none
Natural weapons/Powers:
Horn (1D10)
Medium natural body armour
Advanced smell
Vestigial traits:
Musk glands
Diet: Ruminant
Colour blindness
Vestigial tail
More difficult, as the short build attached to this animal cuts the height down terribly, but you can still do it at a very reasonable size
level, which is what determines attribute bonuses and S.D.C. If I also picked the vestigial trait of reptile brain: charge invented by the poster (which is pretty cool), I could increase my size back up to level 14!
