I really appreciate what some of you have suggested, so I've decided to do the following to my sprite / stat spread (for Pulsarush):
1) I'm going to add yellow-orange whiskers. It'll add another color component and will make it look more shrew-like as well as giving me a chance to add some kind of lightning design.
2) The new stat spread is 80 / 100 / 79 / 101 / 70 / 110, putting it at 540 BST - the same as Gyarados, Blissey, Magmortar, Kingdra, Milotic, and Snorlax. It'll still be able to do damage with SD or with a non-boosting Special set, I think.
3) Most importantly, the new typing is Electric/Ghost. I will recolor the purple to have a greyish tint but best of all I won't have to change the tendril-like tail in the final evolution. Also Electric/Ghost fits with what Pulsarush is since one of its abilities is Exterminated. It's the spirit of an exterminated shrew! This also allows me to keep Poison Heal as one of its abilities. The only thing now is I'll have to add some Ghost-type moves. Probably just Shadow Claw, Shadow Ball and Destiny Bond will be enough.
I'll make the design changes at some point but for that sake of my sanity I'm taking a break from my rodents to focus on one of my starters: Squik.
It's in major rough-draft mode right now, but I'm experimenting with eyes at the moment.
Squik is a pure water type whose DW ability is Quick Feet. It'll eventually evolve into the Water/Psychic Hesychuid [
hesychuis (Greek for 'calm one' and often refers to monks or saints) +
squid].
Hesychuid's stats (tentative):
80/120/70/90/80/95
It's powerful enough to hurt something with Meditate but not fast enough to do too much damage unless you utilize Quick Feet + Toxic Orb in which case your sweep will be short.
Some notable moves:
Meditate,
Calm Mind, Agility,
Recover, Wish, Waterfall, Zen Headbutt,
Head Smash, Brick Break, Ice Punch,
Sucker Punch, Aqua Jet, Surf, Scald, Psychic, Psyshock, Focus Blast, Ice Beam, Energy Ball, Giga Drain, Disable, Confuse Ray, Hypnosis
Some other moves:
Poison Jab, Sludge Bomb, Energy Ball, Amnesia, Facade, Slash*, Psycho Cut*, Night Slash*, Air Slash*
*The final evolution will have some form of stick for slashing moves.
