My personal list:
- electric/rock Raptor. Very fast and frail okay-ish physical attacker. Learns extremespeed.
Ability: galvanize and "Tazer"(works like poison touch, but paralyzes opponent)
Design: fragile/wiry, big crazy eyes, twitches occassionally. Basically South Park's Twitch made raptor-mon.
- rock/psychic Parasaurolophus. Slow but fat special wall, relying on its support moves and special attacks. It's pink/purple and looks sluggish, sleepy and feminine. It has a gem embedded in its disproportionately huge horn/fin.
Abilties: Telepathy and Lightning Rod.
Learns psychic moves, power gem, earth power, psychic terrain, trick room, maybe instruct
Grass/Rock OR Electric Rock Stegosaurus
I prefer the raptor to be electric, but it would fit a stego, too. It could look like it carries a generator system on its back with sap sipper as ability
Rock/Ice Saber Toothed Cat. To make up for its abysmal typing, it should be fast and strong, equipped with an arsenal of great STAB moves (stone edge, ice shard, icicle crash) and coverage (such as crunch, elemental fangs, super fang, play rough, close combat etc).
Decent bulk but on the physical side, but nothing to rely on.
Abilities: Strong Jaw and Sheer Force. Maybe something new.
Design: saber tooth cat with blue/white coloring. Shiny is more reddish.
Rock/Fire Triceratops. I know Bastiodon is near enough, but leaves room for a true three-horn.
It shouldn't be nearly as tanky as Bastiodon, and more based on the raw power and recklessness of a charging Triceratops.
Good attack+defense and usable speed to benefit a lot from a choice scarf. It learns moves like Flame Charge, Flare Blitz, Double Edge, Mega Horn, Outrage, Explosion, Drill Run, Head Smash, Wild Charge.
Design: Overall looks like a brittled triceratops-shaped rock with a heated lava core shimmering through the cracks of its body. Smoke comes out of its nostrils+angry eyes always focused on the target.
Ability: Reckless and Plasmatize(Fire type Pixilate)
